Wiring, Optional Accessories | Chromalox PG433-1 specs

WIRING

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.

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.

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.

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.

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.

OPTIONAL ACCESSORIES

Chromalox STAR series radiant heaters can be field modified by adding optional kits. Refer to Chart A and B to select the proper kit.

Disconnect Kit

The disconnect kit consists of a complete assembly consisting of a disconnect switch (3 Pole), power terminal block and all hard- ware to complete the installation. This kit can be mounted to both the fixed, overhead heater or the portable heater; see instruction bulletin PG436 for details.

Cord Kits

Cord kits consist of 25 feet of 90°C cable and a right angle cord fitting which can connect directly to the heater terminal box or dis- connect switch (if used). See installation bulletin PF491 for details

Plugs

Single and three phase with ground. Available in nonlocking and locking. See Chart B.

Tip Over and Ground Fault Kits

Star Tip Series Kit attaches to portable heater and de-energizes the heater in the event it is tipped over.

Star-TG Series Kit combines the tip over and ground fault fea- ture for portable heaters. See installation bulletin PG436.
