2.1 Cautions on wiring
Danger
Prohibited
• Never remove the front cover when power is on or open door if enclosed in a
cabinet.
The unit contains many high voltage parts and contact with them will result in
electric shock.
Mandatory
• Turn power on only after attaching the front cover or closing door if enclosed in a
cabinet.
If power is turned on without the front cover attached or closing door if enclosed in
a cabinet. This can result in electric shock or other injury.
• Electrical construction work must be done by a qualified expert.
Connection of input power by someone who does not have that expert knowledge
may result in fire or electric shock.
• Connect output terminals (motor side) correctly.
If the phase sequence is incorrect, the motor will operate in reverse and that may
result in injury.
• Wiring must be done after installation.
If wiring is done prior to installation that may result in injury or electric shock.
• The following steps must be performed before wiring.
①Shut off all input power.
②Wait at least 15 minutes and check to make sure that the charge lamp is no
longer lit.
③Use a tester that can measure DC voltage (400VDC or more), and check to
make sure that the voltage to the DC main circuits (across PA/+-PC/C) is 45V or
less.
If these steps are not properly performed, the wiring will cause electric shock.
• Tighten the screws on the terminal board to specified torque.
If the screws are not tightened to the specified torque, it may lead to fire.
Be
Grounded
• Ground must be connected securely.
If the ground is not securely connected, it could lead to electric shock or fire when a
malfunction or current leak occurs.
