Prevent foreign matter from entering the equipment during operations. Otherwise,
equipment damage, load power derating, power failure, or personal injury may
occur.
For the equipment that needs to be grounded, install the ground cable rst when
installing the equipment and remove the ground cable last when removing the
equipment.
Do not route cables behind the air intake or exhaust vents of the equipment.
General Requirements
● Installation, operation, and maintenance must be performed in the sequence
specied in the manual. Do not change the structure or installation sequence
of the equipment without permission.
● Install temporary fences or warning ropes and hang "No Entry" signs around
the operation area to keep unauthorized personnel away from the area.
● Before installing or removing power cables, turn
o the switches of the
equipment and its upstream and downstream switches.
● Before performing operations on the equipment, check that all tools meet the
requirements and record the tools. After the operations are complete, collect
all of the tools to prevent them from being left inside the equipment.
● Before connecting power cables, check that cable labels are correct and cable
terminals are insulated.
● When installing the equipment, use a torque tool of a proper measurement
range to tighten the screws. When using a wrench to tighten the screws,
ensure that the wrench does not tilt and the torque error does not exceed
10% of the
specied value.
● Ensure that bolts are tightened with a torque tool and marked in red and blue
after double-check. Installation personnel mark tightened bolts in blue.
Quality inspection personnel
conrm that the bolts are tightened and then
mark them in red. (The marks should cross the edges of the bolts.)
● It is recommended that the three-phase loads be equalized and the neutral-
ground voltage be kept at less than 2 V (ignore this point if no neutral wire is
required) to meet power distribution requirements.
