General Recommendations

WARNING!
Hazardous Voltage - Pressurized Burning Fluid:
Before removing compressor terminal box cover for
servicing, or servicing power side of control panel,
CLOSE COMPRESSOR DISCHARGE SERVICE VALVE
and disconnect all electric power including remote
disconnects. Discharge all motor start/run capacitors.
Follow lockout/tagout procedures to ensure the
power cannot be inadvertently energized. Verify with
an appropriate voltmeter that all capacitors have
discharged.
The compressor contains hot, pressurized refrigerant.
Motor terminals act as a seal against this refrigerant.

Use Copper Conductors Only!
53 47
Unit terminals are not designed to accept other types
56 50
of conductors. Failure to use copper conductors could
result in equipment damage.
Important:
To prevent control malfunctions, do not run low voltage
wiring (<30 V) in conduit with conductors carrying more
than 30 volts.

Frequency converters contain DC-link capacitors that
58 51
can remain charged even when the frequency converter
62 56
is not powered. To avoid electrical hazards, disconnect
65 59
58 51
AC mains, any permanent magnet type motors, and
62 56
any remote DC link power supplies, including battery
65 59
backups, UPS and DC-link connections to other

frequency converters. Wait for the capacitors to fully 71 64
75 69
discharge before performing any service or repair work.

table. Failure to wait the specified time after power has
74 69
been removed before doing service or repair could result
in death or serious injury.
