Install Single Point Box

See Tables 1 and 2 to determine the correct single point box accessory for the selected heater. The appropriate single point box is determined by the MOCP (maximum overcurrent protection) for the heater and unit combination. Refer to the correct figure for correct installation of the single point box components.

Single point accessories CRSINGLE028A00 and CRSINGLE030A00 are for use on units where the combined MOCP rating is less than 60 amps. These accessories contain

only a terminal block; no fuses are provided. Fuses are not required per the National Electrical Code in these single point accessories since the circuit is below 60 amps. Field−supplied pressure connectors (Kerneys) may be used in place of these single point boxes.

All fuses provided in the single point boxes are rated at 60 amps.

2.Using the screws provided, install the terminal blocks and fuse blocks (if required). (See Fig. 6-12.)

3.If required, using the wires provided, connect the terminal block to the fuse block. (See Fig. 13-22.)

4.Route power wires from the control box and electric heaters into the single point box. Route power wires from the disconnect into the single point box through power entry hole located next to the access panel. Make all wiring connections.

5.If single point box has fuses, install hinged cover using rivets provided. Install magnetic latch in rectangular hole. (See Fig. 7-10 and 12.)

6.Install wiring label on back of single point box access panel or on hinged cover.

7.Replace single point box access panel removed in item 1. Configuring the ComfortLinkt Control

The ComfortLink control must be configured for Electric Heat (default is No Heat). In addition, if a single-stage electric heater has been installed, it will be necessary to change the N.HTR configuration (2 is the default setting). These configurations are changed through the Scrolling Marquee Display or a Carrier network device.
