The Control/VSD Cabinet contains lethal
high AC and DC voltages. Before per-
forming service inside the cabinet, remove
the AC supply feeding the chiller and
verify using a non-contact voltage sensor.
The DC voltage on the VSD DC Bus will
take 5 min to bleed off, after AC power
is removed. Always check the DC Bus
Voltage with a Voltmeter to ensure the
capacitor charge has bled off before work-
ing on the system.
NEVER short out the DC Bus to dis-
charge the filter capacitors.
NEVER place loose tools, debris, or any
objects inside the Control Panel/VSD
Cabinet.
