B.3 Electrical

WARNING Disconnect heater from power supply at integral disconnect or fuse box before opening enclosures or servicing heater.
Lock the switch in the “OFF” (open) position and tag the switch to prevent unexpected power application.
This heater should only be serviced by qualified personnel with electrical heating equipment experience.
Install and use the heater in accordance with local codes and this manual.

1. General
   0.1 Use only approved copper conductors for installation. Refer to Section G -Technical Data, pagel4 and heater data plate for conductor rating.
   0.2 The power supply may be single or three phase as shown on the nameplate. Wiring diagrams are located on the inside of the control cabinet door (or refer to 8.4 Sample Wiring Schematics- GX Series Heater, page 8.

2. Field Wiring
   0.1 Select a conduit style and conduit entrance fitting suitable for EEMAC 12 (dust tight and drip tight – indoor) applications. This is important since contamination of the control cabinet interior could significantly reduce the operating life of the control components.
   0.2 Remove the cabinet door to facilitate electrical access and connection.
   0.3 The control cabinet of the heater is constructed to EEMAC 12 standards and as such, we are not permitted to supply knockouts. After selection of the conductor and conduit entrance sizes, punch the appropriate hole into the control cabinet. We recommend the hatched area indicated in Figurel- Mounting Clearance “Wiring Entrance Area – Top View”, page 4 be used for ease of internal electrical connection.
   0.4 Grounding – a ground lug is located beside the terminal block. Ensure the unit is properly grounded before energizing.
   0.5 The heater is completely prewired internally. Connect the power conductors and any control conductors to the terminals as illustrated on the wiring diagram located inside the control cabinet door.

3. Motor Rotation – Important
   0.1 Three phase heaters are supplied with motors of corresponding phase. The proper motor/fan rotation, viewed from the rear of the heater is counter clockwise. Incorrect rotation of the fan will cause the heater to overheat and cycle on the high limit. To reverse the fan rotation, interchange two supply voltage conductors connected to lugs L1, L2.

4. Temperature Control
   0.1 guilt-In Thermostat – heaters with a factory installed thermostat have all other standard controls such as contactors, and transformers factory installed and prewi red.
   0.2 Thermostat Kit Fat-RA – (Field installed Install the FAT-8A thermostat kit in accordance with the instruction sheet provided.
   0.3 Remote I ine Vol taae Thermostat -A remote thermostat rated to operate as a pilot duty, inductive device on 240V is required. For proper installation and wiring of the selected thermostat, refer to the manufacturer’s instructions. Thermon can supply appropriate thermostats.
   0.4 Remota I ow Voltage Thermostat< – The heater can be provided with a low voltage control internally wired for remote connection to 24V thermostats. Ensure that this control option is installed in the heater before energizing a low voltage thermostat from the heater. For proper installation and wiring of the selected thermostat, refer to the manufacturer’s instructions. Thermon can supply low voltage thermostats for use with heaters.

5. “Continuous Fan” Feature (Summer Switch)
   0.1 The “Continuous Fan” feature will allow the heater to cycle in a “heat” mode dictated by the controlling thermostat, even though the fan is operating continuously. 0.2 Terminals are provided for remote mount of a S.P.S.T. “Continuous Fan” switch, rated 240V 60 Hz. A jumper across terminals “T2” and “T3” is installed at the factory, and must be removed and substituted with the remote switch leads if this feature is to be available. Refer to Section B.4 Sample Wiring Schematics – GX Series Heater, page 6 to 9.
   0.3 A “Continuous Fan” switch may be factory installed (optional feature) directly in the heater.

6. Fan Delay
   0.1 All heaters incorporate a fan delay feature in both the “ON” and “OFF” cycles. This is a desirable feature allowing the heater to come to temperature before the fan operates (no cold blasts) and to cool down in the “OFF” cycle (longer life for the control components and motor). Delay “ON” is 20-50 seconds and delay “OFF” is 20-70 seconds.

7. Remote Energy Management Control
   0.1 Remote energy management control is standard on 40 kW and 50 kW units. Internal power to contactor coil C2 may be interrupted and controlled remotely by removing the jumper between terminals “T2” and “T3”, and then connecting a passive contactor in its place. A closed contact will allow 100% heating capacity and an open contact will allow 50% heating capacity. Refer to Section B.4 Sample Wiring Schematics – GX Series Heater, page 6 to 9.

8. Final Inspection
   0.1 Before application of electrical power:
   0.2 Check that all connections are secured and comply with the applicable code requirements.
   0.3 Confirm that the supply voltage is compatible with the data plate specifications.
   0.4 Remove any foreign objects from the heater.
   0.5 Ensure all external fittings and enclosure covers are secured.
