INSTALLATION
Preliminary Procedure
WARNING
HAZARDOUS VOLTAGE CAN CAUSE
SEVERE INJURY OR DEATH.
LOCK ALL POWER SOURCES
FEEDING DRIVE IN “OFF” POSITION.
1. Disconnect all electrical power to drive.
2. Remove drive front cover.
3. Verify that voltage has been disconnected by
using a voltmeter to check for voltage at the incoming
power terminals.
Mounting and Wiring Units
IMPORTANT
Since the braking resistor unit generates heat
during dynamic braking operation, install it in a
location away from other equipment which
emits heat.
