Acceptance Criteria
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.
After the BCU is removed, set a multimeter to the DC voltage mode
and measure the voltage between the uncoated part of the battery
cabinet and the positive and negative terminals of batteries
respectively. If the readings are less than 6 V DC, the insulation is
good. Otherwise, contact technical support engineers.
All the covers are reinstalled after checks are performed.
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.
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).
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.
