7. PRECAUTIONS FOR MAINTENANCE AND INSPECTION
7.1 Inspection item

2.

Be careful not to bend the pins of the converter unit's control circuit connector, reinstall the control circuit terminal
block, and fix it with the screws.

NOTE

• Before starting the replacement, power OFF the converter unit, wait for at least 10 minutes, and then check that the charge

lamp is OFF to ensure safety.



Removal and reinstallation precautions

Precautions to be taken when removing or reinstalling the control circuit terminal block are shown below.
Observe the following precautions and handle the converter unit properly to avoid malfunctions or failures.

• To remove or reinstall the control circuit terminal block, keep it upright so that it is parallel with the converter unit.
• To install the control circuit terminal block, slide it upward so that the tongues on the converter unit slot into the grooves

on the terminal block.

• Check that the terminal block is parallel to the converter unit and the pins on the converter unit's control circuit connector

are not bent. After checking proper connection, fix the terminal block in place with two screws.

NOTE

• Do not tilt the terminal block while tightening the screws or removing it from the converter unit. (Otherwise, stress applied to

the control circuit terminal block or the control circuit connector may damage the pins.)

• After replacing the control terminal block, connect the jumper connector to the correct position in accordance with the control

logic of input signals. (Refer to

Loosen the screws

Tighten the screws.

A

Slot the tongue into

the groove.

Insert the terminal

block parallel to the

converter unit.
