Verifying the Installation

01

Cabinet installation

The cabinet is securely installed and does not tilt due to vibration.

02

Neat arrangement

The adjacent cabinets are neatly arranged and secured with connecting kits.

03

Cable layout

Cables are routed properly as required by the customer.

04

Cable labels

Both ends of a cable are labeled. Labels are concise and easy to understand.

05

Cable ties

Distances between cable ties are the same, and no burr exists.

06

Cable or copper bar connections

Battery cables or copper bars are securely connected, the spring washers are crimped properly for cables secured by screws, and the cables are intact.

07

Grounding

The resistance between the cabinet ground bar and the equipment room ground bar is less than 0.1 ohm.

08

Battery cables

1. The cabinet is correctly connected to the UPS.
2. Battery cabinets in parallel are correctly connected.
   NOTE:

   When ensuring that the SmartLi and UPS are not powered on:

   • If cabinets are installed close to each other, use a multimeter to check whether the copper bars of the corresponding polarity in the adjacent cabinets are conducted to verify the wiring polarity.
   • If cabinets are installed far away from each other, short-circuit any wiring copper bar and PE (enclosure) in one cabinet, and use a multimeter to check whether the copper bar of the corresponding polarity in another cabinet are conducted with PE (enclosure) to verify the wiring polarity. Before the copper bar in cabinet 1 is short-circuited with PE, the copper bar of the corresponding polarity in cabinet 2 should not be conducted with PE. After the copper bar in cabinet 1 is short-circuited with PE, the copper bar of the corresponding polarity in cabinet 2 should be conducted with PE. After the check is complete, remove the cable between the copper bar and PE.
3. The battery neutral wire (if any) is correctly connected.

09

Short-circuit at the upstream and downstream to circuit breakers

Check whether there is a short circuit between the positive, neutral, and negative cables for circuit breakers, between copper bars, and between cables and ground. If there is a short circuit, check whether the cables are damaged or short-circuited. If yes, repair the cables.

10

Pressure gauge

If the pressure gauge pointer at the front door of the cabinet is obviously lower than the initial position, contact technical support.

11

Foreign matter cleaning inside the cabinet

The inside and outside of the cabinet are free from conductive dust or other sundries.

1. There is no foreign matter (such as copper wires and screws) on the top of the cabinet.
2. There is no foreign matter on the copper bar terminals.
3. There is no foreign matter around circuit breaker terminals.
4. There is no foreign matter on the bottom plate of the cabinet.
5. There is no foreign matter on the rear module subrack.

12

Insulation between battery modules and the cabinet

Set the multimeter to the buzzer mode and use it to test the connection between the copper bars for serial connection of any battery modules of each battery string in the cabinet and the battery tray. If the multimeter does not buzz, the insulation is good. If the multimeter buzzes, contact technical support.

13

Cover installation

All the covers are reinstalled after checks are performed.

14

Storage environment

After the installation is complete, do not store the equipment in an environment where the temperature and humidity are uncontrollable for a long period of time. Otherwise, the equipment may be damaged due to condensation.

15

Insulation resistance of output power cables

The battery cabinet output cables are intact. The insulation resistance of the positive, negative, and neutral output cables to the ground and that between the positive, negative, and neutral output cables are greater than 2 megohms (using a 500 V megohm meter).

16

Installation protection

If batteries will not be powered on after installation, take dustproof and anti-condensation measures (for example, use a dust cover, plastic film, or fabric cloth) to prevent condensation and dust buildup, which may corrode the batteries. Remove the protective objects when batteries need to be used.
