A.
STANDARD MODEL
1.
All electrical wiring must comply with local codes.
2.
Electrical power supply requirements for standard units
are identified on the equipment data tag. Determine
that the plant’s voltage supply is the same as the unit’s
voltage requirements, taking into account the SSCR
Rating.
3.
A customer supplied, four conductor cable is
required for connection to a customer supplied fused
disconnecting means. The fused disconnecting
means shall be sized and installed according to the
unit’s power supply requirements and local electrical
codes. (Some custom units may include a fused or
non-
fused disconnect switch. “Fused” may be fuses
on circuit breaker.)
4.
Connect the four conductor power cable to the power
entry terminal block on the unit’s electrical panel.
Data tag.
5.
Then connect the power cable to the fused disconnect switch. There is no power
entry hole into the electrical cabinet. This allows the matching of the entry hole
size and location to the customer supplied fittings.
6.
A unit specific electrical drawing is shipped with the unit.
7.
Voltage supplies must be /- 10% of the name plate voltage and must be
within 2% from leg to leg. Extreme voltage imbalance or using the wrong voltage
can damage your chiller and cause premature unit failure as well as a safety risk.
8.
A proper ground is required for the unit.
B.
CONTROL CIRCUIT WIRING
1.
The unit’s will supply its internal control circuit is single phase 115 volt 60Hz or
single phase 110 volt 50 Hz. The voltage and hertz are dependent on the hertz
of the connected grid.
2.
The control circuit is supplied by the factory installed transformer. A control circuit
fuse is provided.
C.
GENERAL
1.
Make certain all ground connections to the unit are properly affixed.
2.
Make certain power conductor, disconnecting means, and fusing are properly
sized according to the unit’s power supply requirements.
3.
Follow all local and national codes.
4.
Make certain that all owner and factory wire connections are tight before applying
power to the unit.
