No. Item Acceptance Criteria
11 Insulation between
battery modules
and the cabinet
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.
12 Cover installation All the covers are reinstalled after checks are
performed.
13 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).
14 Installation
protection and
storage
environment
1. If the equipment will not be powered on after
installation, take dustproof measures (for
example, use a dust cover) to prevent
equipment damage due to dust buildup inside
it. Remove the dust cover only when the
equipment is ready for operation.
2. After the installation is complete, take anti-
condensation measures and keep the air
conditioner running. 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.
Do not remove the dust cover during construction or before the device is powered
on. Remove the cover only when the device is ready for operation. Otherwise,
device faults may occur.
