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.
NEVER allow the Control Panel VSD
Cabinet doors to remain open if there is a
potential for rain to enter the panel. Keep
doors closed and ensure that all latches
are engaged on each door unless the unit
is being serviced.
ALWAYS lockout the disconnect supply
-
ing AC to the chiller.
The 1L Line Inductor will reach operating
temperatures of over 300°F (150°C). DO
NOT open panel doors during operation.
Ensure that the inductor is cool whenever
working near the inductor with power
OFF.
