Carrier installation instructions 19XR with Free-Standing Starter

Page 31

Free-Standing,Field-Installed Starter Ð Assemble and in- stall compressor terminal box in desired orientation, and cut necessary conduit openings in conduit support plates. See Fig. 27 and 29. Attach power leads to compressor terminals in accordance with job wiring drawings, observing caution label in terminal box. Use only copper conductors. The mo- tor must be grounded in accordance with NEC (National Elec- trical Code), applicable local codes, and job wiring diagrams. Installer is responsible for any damage caused by improper wiring between starter and compressor motor.

IMPORTANT: Do not insulate terminals until wiring arrangement has been checked and approved by Carrier start-up personnel. Also, make sure correct phas- ing is followed for proper motor rotation.

Insulate Motor Terminals and Lead Wire Ends Ð Insulate compressor motor terminals, lead wire ends, and electrical wires to prevent moisture condensation and electrical arc- ing. For low-voltage units (up to 600 v), obtain insulation material from machine shipping package consisting of 3 rolls of insulation putty and one roll of vinyl tape.

1.Insulate each terminal by wrapping with one layer of in- sulation putty.

2.Overwrap putty with 4 layers of vinyl tape.

High Voltage Units Ð High-voltage units require special ter- minal preparation. Follow local electrical codes for high- voltage installation. Vinyl tape is not acceptable; a high voltage terminal method must be used.

Connect Power Wires to Oil Pump Starter Ð See Fig. 30. Connect power wires to oil pump starter mounted in ma- chine power panel. Use separate fused disconnect or circuit breaker as shown on job wiring diagrams and Fig. 30. Check that power supply voltage agrees with oil pump voltage. Fol- low correct phasing for proper motor rotation.

Do not punch holes or drill into the top surface of the power panel. Knockouts are provided in the bottom of the power panel for wiring connections.
