Do not drill holes into a cabinet without permission. Non-standard drilling may affect the
electromagnetic shielding of the cabinet and damage interior cables. Metal shavings from
drilling may short-circuit circuit boards if they enter the cabinet.

The power system is powered by high-voltage power sources. Direct or indirect contact
(through damp objects) with high-voltage power sources may result in serious injury or
death.
Non-standard and improper operations may result in fire and electric shocks.
Before making electrical connections, turn off the protection switch on the upstream
device to cut the power supply.
Before connecting the AC power supply, ensure that electrical connections are complete.
Before connecting cables to loads or battery cables, check cable and terminal polarities
to avoid reverse connections.
Electrostatic discharge (ESD)
− To prevent electrostatic-sensitive components from being damaged by static from
human bodies, wear a grounded electrostatic discharge (ESD) wrist strap or ESD
gloves when touching circuit boards.
− When holding a board, hold its edge without touching any components, especially
chips.
− Package boards with ESD packaging materials before storing or transporting them.
Cables must be routed so that a sufficient distance exists between the cables and the DC
busbar, shunt, and fuse. This prevents damage to the insulation layer of the cables.
Signal cables must be bound separately from strong-current cables and high-voltage
cables.
Cables prepared by the customer must have the fire resistance capability.
Drilling holes
Before drilling holes into a cabinet, remove interior cables.
Wear goggles and protective gloves when drilling holes.
After drilling, clean up metal shavings immediately.
Moving heavy objects
− Be cautious to avoid injury when moving heavy objects.
− Wear protective gloves when moving sharp objects.
