Chapter 1: Important Safety Warnings

Please comply with all warnings and operating instructions in this manual strictly. Save this manual properly and read carefully the following instructions before installing the unit. Do not operate this unit before reading through all safety information and operating instructions carefully.

1.1 Transportation

• Please transport the UPS system only in the original package to protect against shock and impact.

1.2 Preparation

• Condensation may occur if the UPS system is moved directly from a cold to a warm environment. The UPS system must be absolutely dry before being installed. Please allow at least two hours for the UPS system to acclimate to the environment.
• Do not install the UPS system near water or in moist environments.
• Do not install the UPS system where it would be exposed to direct sunlight or near a heater.
• Do not block ventilation holes in the UPS housing.

1.3 Installation

• Do not connect appliances or devices that would overload the UPS system (e.g., laser printers) to the UPS output sockets.
• Please do not attach half-sinewave load or motor load to the UPS.
• Place cables in such a way that no one can step on or trip over them.
• Do not connect domestic appliances such as hair dryers to the UPS output sockets.
• The UPS can be operated by any individuals with no previous experience.
• Connect the UPS system only to an earthed shockproof outlet which must be easily accessible and close to the UPS system.
• Please use only VDE-tested, CE-marked mains cable (e.g., the mains cable of your computer) to connect the UPS system to the building wiring outlet (shockproof outlet).
• Please use only VDE-tested, CE-marked power cables to connect the loads to the UPS system.
• When installing the equipment, ensure that the sum of the leakage current of the UPS and the connected devices does not exceed 3.5mA.

1.4 Operation

• Do not disconnect the mains cable on the UPS system or the building wiring outlet (shockproof socket outlet) during operations, as this would cancel the protective earthing of the UPS system and of all connected loads.
• The UPS system features its own internal current source (batteries). The UPS output sockets or output terminals block may be electrically live even if the UPS system is not connected to the building wiring outlet.
• To fully disconnect the UPS system, first press the OFF/ ENTER button to disconnect the mains.
• Prevent fluids or other foreign objects from entering the UPS system.

1.5 Maintenance, Service and Faults

• The UPS system operates with hazardous voltages. Repairs may be carried out only by qualified maintenance personnel.
• WARNING: Risk of electric shock. Even after the unit is disconnected from the mains (building wiring outlet), components inside the UPS system are still connected to the battery and are electrically live and dangerous.
• Before carrying out any kind of service and/or maintenance, disconnect the batteries and verify that no current is present and no hazardous voltage exists in the terminals of high capability capacitors such as BUS-capacitors.
• Only persons adequately familiar with batteries and with the required precautionary measures may replace batteries and supervise operations. Unauthorized persons must be kept well away from the batteries.
• WARNING: Risk of electric shock. The battery circuit is not isolated from the input voltage. Hazardous voltages may occur between the battery terminals and the ground. Before touching, please verify that no voltage is present!
• Batteries may cause electric shock and have a high short-circuit current. Please take the precautionary measures specified below and any other measures necessary when working with batteries:
  • - Remove wristwatches, rings, and other metal objects.
  • - Use only tools with insulated grips and handles.
• When changing batteries, install the same number and same type of batteries.
• Do not attempt to dispose of batteries by burning them, as this could cause battery explosion.
• Do not open or destroy batteries. Escaping electrolyte can cause injury to the skin and eyes. It may be toxic.
• Please replace the fuse only with the same type and amperage to avoid fire hazards.
• Do not dismantle the UPS system.

1.6 Packing List

The following items are included in the package:

Chapter 2: Installation and Setup

NOTE: Before installation, please inspect the unit. Be sure that nothing inside the package is damaged. Please keep the original package in a safe place for future use.

2.1 Rear Panel View

The rear panel configuration varies slightly between Standard Runtime and Extended Runtime models.

Standard Runtime Model

1 kVA / 2 kVA / 3 kVA Rear Panel Layout:

• 1: AC input
• 2: Input circuit breaker
• 3: USB port
• 4: RS-232 port
• 5: Mini slot
• 6: Output socket(s)
• 7: External battery connector (Not present on standard models)
• 8: Output terminal (for 3kVA models)

Extended Runtime Model

1 kVA / 2 kVA / 3 kVA Rear Panel Layout:

• 1: AC input
• 2: Input circuit breaker
• 3: USB port
• 4: RS-232 port
• 5: Mini slot
• 6: Output socket(s)
• 7: External battery connector
• 8: Output terminal (for 3kVA models)

2.2 Operating Principle

The UPS operates by conditioning the incoming AC power. In normal operation, AC power is filtered, rectified to DC, and then inverted back to stable AC power for the output. When utility power fails or is out of tolerance, the UPS draws power from its internal batteries, converts it to DC, and then inverts it to AC output. A bypass line is also available to supply utility power directly to the output when conditions are normal and stable.

Diagram Description: Input power flows through TVSS & EMI/RFI Filters. It then goes to a Rectifier/PFC unit, which converts AC to DC. This DC power charges the Battery via a Battery Charger and also powers a DC-to-DC Converter. The DC-DC Converter supplies power to the Inverter, which converts DC back to AC for the Output. An Input Relay controls the power flow from the input to the rectifier, and an Output Relay controls the power flow from the inverter to the output. The system also includes a Bypass line.

2.3 Setup the UPS

Step 1: Connect battery wires

If the UPS is an Extended Runtime model, connect external batteries using the provided battery cable. Secure the battery cable to the terminal with the supplied screws and nuts.

Step 2: UPS input connection

Plug the UPS into a two-pole, three-wire, grounded receptacle only. Avoid using extension cords.

The power cord is attached to the UPS. The type of power cord depends on the model and region:

Step 3: UPS output connection

• For socket-type outputs, simply connect devices to the outlets.
• For terminal-type outputs (typically on 3kVA models), follow these steps for wiring configuration:
  1. Remove the small cover of the terminal block.
  2. For 3kVA models, it is suggested to use AWG12~10 or 3.3mm²~5.3mm² power cords. Install a circuit breaker (40A) between the mains and the AC input of the UPS for safety operation.
  3. Upon completion of the wiring configuration, check that the wires are securely affixed.
  4. Replace the small cover back onto the rear panel.

Step 4: Communication connection

To allow for unattended UPS shutdown/start-up and status monitoring, connect a communication cable from the USB or RS-232 port on the UPS to the communication port of your PC. With the monitoring software installed, you can schedule UPS shutdown/start-up and monitor UPS status.

The UPS is equipped with a mini slot for optional cards like Delta mini SNMP, Relay I/O, Modbus, or TVSS cards, providing advanced communication and monitoring options.

NOTE:

• The USB port and RS-232 port cannot work simultaneously.
• If using the USB port, install the USB driver software on your computer after connecting it to the UPS. The software can be downloaded from: www.deltapowersolutions.com/en-in/mcis/1kva-3kva-single-phase-ups-inx-series-downloads.php

Step 5: Turn on the UPS

Press and hold the ON/MUTE button on the front panel for two seconds to power on the UPS.

NOTE: The battery charges fully during the first five hours of normal operation. Do not expect full battery run capability during this initial charge period.

Step 6: Install software

For optimal computer system protection, install the UPS monitoring software to configure UPS shutdown. Download the software from: www.deltapowersolutions.com/en/mcis/software-center.php

Chapter 3: Operation

3.1 Button Operation

The UPS features several buttons on its front panel for control and setting:

• ON/MUTE Button:
