ATTENTION: This drive 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 procedures are not followed. If you are not familiar with static control procedures, reference publication 8000-4.5.2,
“Guarding Against Electrostatic Damage” or any other applicable
ESD protection handbook.
ATTENTION: To avoid a shock hazard, assure that all power to the drive has been removed before proceeding with the following procedure. In addition, verify that the DC bus has discharged by measuring across the “+DC” and “–DC” terminals of TB1 with a voltmeter. The voltage should be 0.0VDC.
1.
Remove and lock-out all incoming power to the drive.
2.
Remove front cover or entire enclosure as required for adequate access.
3.
If a HIM is installed, remove the module by sliding it down and out of the cradle.
