Installation
RT-SVX37B-EN 23
installed at or near the unit in accordance with the
National Electrical Code (NEC latest edition).
Main Unit Power
Standard Wiring
1. Location of the applicable electrical service entrance is
illustrated in
“Unit Dimensions,” p. 11 . Complete the
unit’s power wiring connections at Compressor
Contactor # 1 (CC1) inside the unit control panel. Refer
to the customer connection diagram that is shipped
with the unit for specific termination points.
2. Provide proper grounding for the unit in accordance
with local and national codes.
Field Installed Control Wiring
An overall layout of the various control options available
with the required number of conductors for each control
device is illustrated in
Figure 29, p. 27 .
Control Power Transformer
The 24 volt control power transformers are to be used only
with the accessories called out in this manual.
Transformers rated greater than 50 VA are equipped with
internal circuit breakers. If a circuit breaker trips, turn “Off”
all power to the unit before attempting to reset it.
The transformer is located in the control panel. The circuit
breaker is located on the left side of the transformer and
can be reset by pressing in on the black reset button.
Controls using 24 VAC
Before installing any connecting wiring, refer to “Unit
Dimensions,” p. 11 for the electrical access locations
provided on the unit and Table 3 for AC conductor sizing
guidelines, and;
1. Use copper conductors unless otherwise specified.
2. Ensure that the AC control wiring between the controls
and the unit’s termination point does not exceed three
(3) ohms/conductor for the length of the run.
Note: Resistance in excess of 3 ohms per conductor may
cause component failure due to insufficient AC
voltage supply.
Note: Be sure to check all loads and conductors for
grounds, shorts, and mis-wiring.
3. Do not run the AC low voltage wiring in the same
conduit with the high voltage power wiring.
4. Route low voltage wiring per Figure 26, p. 24 .
WARNING
Proper Field Wiring and Grounding
Required!
• All field-installed wiring must be completed by
qualified personnel. All field-installed wiring must
comply with NEC and applicable local codes.
• Follow proper local and state electrical code on
requirements for grounding.
Failure to follow this instructions could result in death
or serious injuries.
WARNING
Hazardous Voltage!
Disconnect all electric power, including remote
disconnects before servicing. Follow proper lockout/
tagout procedures to ensure the power can not be
inadvertently energized. Failure to disconnect power
before servicing could result in death or serious injury.
