2. Floor Installation with Base

2-1 Installation Location Requirements

Wall Clearance: ≥300mm

Ground Clearance: ≥300mm

Distance from wall (side): ≥300mm

Distance from front: 500mm ≤ d ≤ 600mm

Note:

• If more than 4 batteries are used, base mounting is recommended.
• For floor installation with base, the maximum stack number of the battery is ten. But if the battery number is greater than six, stacking in two lines is recommended.

2-2 Installation Procedure

Diagrams illustrate the step-by-step procedure for floor installation with a base, including stacking batteries and installing safety parts. The safety part should be installed at the top battery. If the battery pack is higher than 7, an additional safety part should be installed in the middle battery.

3. Wall-Mounted Installation Process

3-1 Installation Location Requirements

Wall Clearance: ≥300mm

Ground Clearance: ≥300mm

Distance from wall (side): ≥300mm

Distance from front: 500mm ≤ d ≤ 1000mm

Note: The number of wall-mount installations should not exceed four. Ensure the weight capacity of the wall exceeds 150kg.

3-2 Installation Procedure

Diagrams detail the wall-mounting installation procedure, including attaching the wall bracket, mounting the battery, and securing it. A note indicates to adjust the screw to ensure the battery is in a horizontal position.

4. Install Environment

Diagrams show the battery system installed on a wall, protected from direct sunlight and rain. A note advises building a sun and rain shade.

Wiring diagrams show the connection between the battery system and the PCS using CAN cables and insert plugs. The diagrams illustrate connections for both ARK 2.5H-A2 series cables and ARK 2.5H-A2 cables.

Notes:

• Ensure the voltage difference of the battery pack is less than 0.5V before installation.
• For the same system, it is recommended to use batteries with a manufacturing date difference within 3 months to avoid capacity limitations.
• If a switch is used between the PCS and the battery, a circuit breaker with a rated voltage greater than 750V and a rated current greater than 63A is recommended.

6. Terminal Connection

6-1 Power terminal

Diagrams show how to connect the power terminal on both the battery side and wire side. A note indicates to press the indicated position before disconnecting the power terminal.

6-2 Communication terminal

Diagrams illustrate the connection of the communication terminal on both the battery side and wire side.
