The units have single point power connection. A single field supplied fused disconnect is required.
The control transformer is factory mounted.
3h.2: Electrical Data Table
Single Point Power Supply Connection
Voltage Range (380-420V/50Hz/3Ph)
Minimum Circuit Amperage (MCA)
Field Fuse Size or HACR
Breaker Size
Rated Load Amps (RLA)
Locked Rotor Amps (LRA)
NOTES:
Voltage within 10% of nameplate rating.
1.
Phase imbalance within 3%.
2.
Single conductors should be used for power connections.
3.
Single point disconnect of electrical supply to the unit is required. This supply must be fused.
4.
Field Fuse Size for recommended and maximum is based on the use of a time-delay fuse.
5.
Compressor RLA values are for wire sizing purposes only and do not reflect normal operating
6.
current draw at rated capacity.
All terminal block connections must be made with copper (type THW) wire.
7.
All field wire size values given in the table apply to 75°C rated wire.
8.
Ampere correction factors must be applied for ambient temperatures in sizing the power lead
