WIRING

2. The heater connection points are located in the gasketed termi-

nal enclosure. To remove cover, remove screw(s) on the cover.

Remove the cover to expose wiring connection points.

3. A green ground terminal is provided in the bottom of the enclo-

sure. The ground wire should be connected before other con-

nections are made.

ELECRIC SHOCK HAZARD. Disconnect all power

before installing or servicing heater. Failure to do

so could result in personal injury or property dam-

age. Heater must be effectively grounded in accor-

dance with the National Electrical Code, NFPA 70.

4. Use type "SO" or equal cord.

Refer to Table 1 for proper cord gage and number of conduc-

tors.

5. All 3 element heaters are factory pre-wired for 3-phase delta

operation. Some units can be converted to single phase operation

by changing the wiring. Refer to Table 1 for those heaters that

can be converted to single phase. The appropriate wiring dia-

gram (Figure 4) is also located on the bottom of the enclosure.

All electrical wiring must be done by a qualified

person in accordance with National Electrical Code

(NEC) and meet all state and local regulations.

1. Use heater only at the voltage specified on the nameplate.

INSTRUCTIONS FOR FIELD CONVERSION FROM 3 PHASE TO 1 PHASE:

1. Remove nuts from all terminals.

2. Remove all pigtail leads and hat shaped buss bar.

3. Remove end of leadwire on terminal 5 and slip onto terminal 4.

4. Remove leadwire attached to instruction sheet and connect between terminals 4 and 6.

5. Install hat shaped buss bar between terminals 3 and 5.

6. Place pigtail lead marked “L1” on to terminal 2 and pigtail lead marked “L2” on to terminal 6.

7. Install nuts.

8. Connect entrance wiring to pigtail leads “L1” and “L2”. Connect ground to screw provided.

9. Inspect to make sure wiring is per “Single Phase Wiring” above.
