1. When battery
strings are
powered off,
check the
reliability of each
connection point
from positive
terminals to
negative
terminals. All
points must be
connected
reliably.
2. Use a torque
wrench to check
the tightening
torque for each
battery screw.
The torque must
meet the
requirements of
the battery
manufacturer.
After checking
that the battery
screws meet the
requirements,
mark the screws
for later check.
