Wire Connection - Thermador PROFESSIONAL PRO HARMONY PRD305PH Manuel D'installation

Observe all governing codes and ordinances when
grounding. In the absence of these codes or ordinances
observe National Electrical Code ANSI/NFPA No. 70
current issue. See the following information in this section
for grounding method.
Electrical wiring diagrams and schematics have been
placed in the kick panel area of the range for access by a
qualified service technician (see Figure 28 on page 21).
The ranges are to be connected to a 240/208 VAC power
supply.
Dual Fuel models must be connected to the power supply
utilizing one of the following methods. For all methods of
connection, the length of the cord or conduit/wiring must
allow the unit to be slid completely out of the cabinet
without having to unplug or disconnect the unit from the
power supply.
Recommended minimum free length of cord or conduit is
4ft (1.2 m). Electrical installations and grounding must be in
accordance with all local codes and ordinances, and/or the
National Electric Code, as applicable.
Permanent Connection (Hard Wiring)
This appliance is manufactured ready to install with a
supplied 4-wire cord set with plug attached to the
appliance. However, units may be hard wired to the power
supply. If the appliance is to be hard wired, the 4-wire cord
set must be removed from the terminal block.
It is the responsibility of the installer to provide the proper
wiring components (conduit, wires, etc.) and complete the
electrical connection as dictated by local codes and
ordinances, and/or the National Electrical Code. It is the
responsibility of the installer to provide the approved
flexible aluminum conduit, ¾'' (19 mm) trade size,
maximum 6 ft (1.8 m) long.
WARNING
Improper connection of aluminum house wiring can
result in a fire or shock hazard. Use only connectors
designed and certified for connecting to aluminum wire.
Locate the terminal block on the rear of the unit and
remove cover (refer to Figure 9). The conduit must be
installed to the terminal block using an approved conduit
connector. The free end of the conduit must be connected
to a terminal block provided in the electrical supply zone,
as shown in Figure 4 on page 8.
English 13
Mount a strain relief (not provided) into the 1" (25.4 mm)
diameter hole located below the terminal block (see
Figure 9). Wiring for the unit is to be brought into the
terminal block through the conduit and through the strain
relief. The ends of the wiring must have 1/4'' (6 mm) faston
closed-loop lugs attached, preferably soldered in place.
Make the connections to the terminal block provided.
If aluminum supply wiring exists in the installation, splice
the aluminum house wiring with appropriate-thickness
gauge copper wire for adapting to the range, using special
connectors designed and certified for joining copper and
aluminum wire. Follow the connector manufacturer's
recommended installation procedure.

4-Wire Connection

This appliance is manufactured ready to install with a
supplied 4-wire cord set with plug attached to the
appliance. If the cord is damaged or must be replaced, use
a Listed (UL, CSA, ...) 3-POLE, 4-CONDUCTOR cord kit
rated 125/250 VOLTS, 50 AMPERES DEDICATED
CIRCUIT, and marked for use with ranges.
The cord kit must be attached to the range terminal block
with a strain relief (not provided) which will fit a 1"
(25.4 mm) diameter hole. If not already equipped, the cord
must also have 1/4'' (6 mm) faston closed-loop lugs
attached to the free ends of the individual conductors,
preferably soldered in place.
1. Locate the terminal block on the rear of the unit and
remove cover (see Figure 9).
2. Remove upper nuts only from the terminal block studs.
Do not remove lower nuts which secure range internal
wiring leads.
3. Mount strain relief (not provided with range) into the 1"
(25.4 mm) diameter hole in the back panel located
below the terminal block. Route wires up through strain
relief.
