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.
