Thermador PRG36, PRG48, PRG304, PRDS48 Location of Junction Box On PRDS304 Range

•3-CONDUCTOR CORD - Where local codes and ordinances permit grounding through neutral, unit may be connected to the power supply with a 3- pole, 3-conductor cord kit rated 125/250 volts, 50 amperes, and marked for use with ranges. The cord kit must be attached to the range junction box with a strain relief which will fit a 1-3/8" diameter hole. If not already equipped, the cord must have #10 closed-loop lugs attached to the free ends of the individual conductors, preferably soldered in place.

Locate the junction box on the rear of the unit and remove cover. Refer to Fig. 16 for PRDS304 range and Fig. 16a for PRDS36 and PRDS48 ranges. Remove the knock out ring in the junction box to provide a 1- 3/8" diameter hole. Install the cord to the junction box, and make the connections to the terminal block provided. Refer to Figures 17 and 17a. The cord kit must be plugged into a mating NEMA 10-50R receptacle provided in the gas and electrical supply zone, as shown in Figures 3b, and 3c on Page 6.

•4-CONDUCTOR CORD - Where local codes and ordinances DO

NOT PERMIT GROUNDING THROUGH NEUTRAL, unit must be connected to the power supply with a 3-pole,4-conduc- tor cord kit rated 125/250 volts, 50 amperes, and marked for use with ranges. The cord kit must be attached to the range junc- tion box with a strain relief which will fit a 1-3/8" diameter hole. If not already equipped, the cord must have #10 closed- loop lugs attached to the free

ends of the individual conduc- tors, preferably soldered in place.

Locate the junction box on the rear of the unit and remove cover. Refer to Fig. 16 for PRDS304 range and Fig. 16a for PRDS36 and PRDS48 ranges. Remove the knock out ring in the junction box to provide a 1-3/8" diameter hole. Remove the ground strap retaining screw and bend the ground strap up. Refer to Fig. 18. Install the cord to the junction box, and make the connections to the terminal block provided. Secure the ground lead from the cord to the junc- tion box with the screw previ- ously used to secure the ground strap. Refer to Fig. 18a. The cord kit must be plugged into a mating NEMA 10-50R receptacle provided in the gas and electrical supply zone, as shown in Figures 3b, and 3c on Page 6.

•PERMANENT CONNECTION (HARD WIRING) - Units may be hard wired to the power supply. The installer must provide approved flexible aluminum conduit, 3/4" trade size, maxi- mum 6 feet long. Locate the junction box on the rear of the unit and remove cover. Refer to Fig. 16 for PRDS304 range and Fig. 16a for PRDS36 and PRDS48 ranges. Remove the ground strap retaining screw and bend the ground strap up. Refer to Fig. 18. The conduit must be installed to the junction box using an approved conduit connector.

Wiring for the unit is to be brought into the junction box through the conduit. Refer to Chart D on Page 16 for rating of wiring and sizing of individual

conductors. The ends of the wiring must have #10 closed- loop lugs attached, preferably soldered in place. Make the connections to the terminal block provided. Secure the ground lead to the junction box with the screw previously used to secure the ground strap. Refer to Fig. 18a. The free end of the conduit must be con- nected to a junction box pro- vided in the gas and electrical supply zone, as shown in Figures 3b and 3c on Page 6.
