1 Installation and Startup Guide
This document covers the installation of the cMT-XMBS Standard Connection Box. For detailed specifications and operation, please refer to the Datasheet, Brochure, and User Manual. Please read all warnings, precautions, and instructions on the device carefully before use.
Install Environment:
Electrical Environment: The product has been tested to conform to European CE requirements. The circuitry is designed to resist electrical noise, but this does not guarantee noise immunity in severe cases. Proper wire routing and grounding are essential for optimal operation.
Environmental Considerations:
- (1) Ensure units are installed correctly and operating limits are followed. Avoid environments with severe mechanical vibration or shocks.
- (2) Do not operate in areas subject to explosion hazards due to flammable gases, vapors, or dusts.
- (3) Do not install where acid gas, such as SO2, exists.
- (4) Mount the unit vertically on a flat surface enclosure.
- (5) For use in Pollution Degree 2 Environment and dry location.
- (6) Relative Humidity: 10% ~ 90% (non-condensing).
IP Rating: IP 66
Cleaning Considerations: Clean the device using dry cloths. Do not use liquid or spray detergents.
Warning: Protection impairment if used in a manner not specified by the manufacturer. Déficit de protection si utilisé d'une manière non spécifiée par le fabricant.
2 Unpacking the Unit
Unpack and check the delivery. If damage is found, please contact the supplier.
NOTE: Place the unit on a stable surface during installation. Dropping or letting it fall may cause damage.
The package includes: (1) Installation Instruction, (2) cMT-XMBS unit.
3 Installation Instructions
Mounting screws: Prepare four M4 or #8 flathead screws to secure the connection box. The mounting hole diameter is 4.6 mm.
Allow adequate clearance around the connection box for ventilation and cable routing. Consider heat generated by nearby devices and ensure the ambient temperature around the connection box remains within 0 ~ 55°C.
Minimum required clearances (from enclosure): Top: 10 mm / Sides: 10 mm / Bottom: 120 mm.
Disassembly and Installation of the Standard Connection Box Front Cover
Parts: Front Cover, Mounting Screws, Cable Glands.
Procedure: Before wiring the Standard Connection Box, remove the front cover and connect the cable:
- Loosen the mounting screws and remove the front cover.
- Route and connect the cable.
- Reinstall the front cover and tighten the mounting screws.
Torque Specifications:
- Mounting screws: 2.1~3.4 lbf-in (ensure waterproofing and prevent damage to the enclosure's screw holes).
- Cable glands (for Ø 4~8 mm cable): 33~48 lbf-in.
Connecting the Handheld HMI to the Standard Connection Box
- Align the red dot on the handheld HMI's cable connector with the red dot on the connection box's cable connector.
- Push the cable connector in firmly until you hear it snap into place, indicating it's fully engaged.
Removing the Standard Connection Box
- Use your thumb and index finger to pull the cable connector's outer ring all the way back.
- Pull the connector straight out to detach.
4 Wiring Terminal Pin Assignment
Connector Specifications: Wire AWG: 24~16, Wire Strip Length: 9~10 mm.
A Wiring Terminal
| 24V Power | Emergency Stop Switch | Key Switch | Ground |
|---|---|---|---|
| 24V+ | STOP NC 1 | KEY NO 1 | |
| 24V+ | STOP NC 2 | KEY NC 1 | |
| 24V- | STOP COM 1 | KEY COM 1 | FG |
| 24V- | STOP COM 2 |
B Wiring Terminal
| 3-Position Enable Switch | RS-485 | LAN | Detect / GND |
|---|---|---|---|
| ENABLE NO 1 | 4W_TX+ | LAN_TX+ | DET_24V |
| ENABLE NO 2 | 4W_TX- | LAN_TX- | |
| ENABLE COM 1 | 2W_DATA+ / 4W_RX+ | LAN_RX+ | GND |
| ENABLE COM 2 | 2W_DATA- / 4W_RX- | LAN_RX- |
CAUTION
Power: Make sure all local and national electrical standards are met when installing the unit. Contact your local authorities to determine which codes apply.
Use power output that meets SELV (Safety Extra-Low Voltage) requirements. The unit can be powered by DC power only, voltage range: 24±20%. The power conditioning circuitry is accomplished by a switching power supply. The peak starting current can be as high as 2A.
Fusing Requirements: If the handheld HMI display does not turn on within 5 seconds of power-up, remove power. The handheld HMI features a resettable fuse to protect against overcurrent faults in the DC circuit; the fuse will reset automatically after a period of time. Check wiring for proper connections and try to power up again.
High Voltage: The handheld HMI's resettable fuse will prevent damage under overcurrent conditions; however, protection is not guaranteed. DC voltage sources must be properly isolated from main AC power and similar hazards.
Emergency Stop: A Hard-wired EMERGENCY STOP should be fitted in any system using an HMI to comply with ICS Safety Recommendations.
Supply Voltage Condition: Do not power the unit and inductive DC loads, or input circuitry to the controller, with the same power supply. Note: The 24 VDC output from some controllers may not have enough current to power the unit.
Wire Routing:
- a. Power wire length should be minimized (Max: 500m shielded, 300m unshielded).
- b. Use twisted pair cables for power wire and signal wire and conform to impedance matching.
- c. If wiring is to be exposed to lightning or surges, use appropriate surge suppression devices.
- d. Keep AC, high energy, and rapidly switching DC power wiring separated from signal wires.
- e. Add a resistor and capacitor in parallel connection between the ungrounded DC power supply and the frame ground. This provides a path for static and high frequency dissipation. Typical values: 1M Ohm and 4700pF.
DANGER
Hardware Considerations: System designers must be aware that devices in Controller systems could fail and thereby create an unsafe condition. Electrical interference can lead to equipment start-up, potentially resulting in property damage and/or physical injury. Take appropriate precautions for programmable control systems, following guidelines like NEMA ICS 3-304 Control Standards.
Programming Considerations: To conform to ICS Safety Recommendations, implement limit checks and safe shut down procedures for writable registers controlling critical plant or machinery parts within the program to ensure personnel safety.
