2.1 Cautions on wiring
Warning
Prohibited

Never remove the terminal cover when power is on.
The unit contains many high voltage parts and contact with them will result in electric shock.
Mandatory
action

Turn the power on only after attaching the terminal block cover.
If the power is turned on without the terminal block cover attached, 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.
(1) Shut off all input power.
(2) Wait at least 15 minutes and check to make sure that the charge lamp is no longer lit.
(3) Use a tester that can measure DC voltage (400VDC or 800VDC or more), and check to make sure
that the voltage to the DC main circuits (across PA/+ - PC/-) is 45V or less.
If these steps are not properly performed, the wiring will cause electric shock.

Tighten the screws on the terminal block to specified torque.
If the screws are not tightened to the specified torque, it may lead to fire.
