Installation
ATTENTION: This board contains ESD (Electrostatic
Discharge) sensitive parts and assemblies. Static control
precautions are required when installing, testing, servicing
or repairing this assembly. Component damage may result if
ESD control precautions are not followed. If you are not
familiar with static control procedures, reference AB
publication 8000-4.5.2, “Guarding against Electrostatic
Damage” or any other applicable ESD protection handbook.

❏ 1 Remove and lock-out all incoming power to the drive. Loosen
the (2) captive retaining screws and remove the drive cover.
❏ 2 Loosen the captive carrier retaining screw and swing the carrier
door open.
ATTENTION: Electric Shock can cause injury or death.
Remove all power before working on this product.
The drive is at line voltage when connected to incoming AC
power. Before proceeding with any installation or
troubleshooting activity, disconnect, lock out, and tag all
incoming power to the drive. Verify with a voltmeter that no
voltage exists at terminals L1, L2 and L3 on the drive input
power terminal block.
