Step 5: Electrical Requirements, Connection And Grounding - Thermador Professional PCG24 Manuel D'installation

CAUTION
The appliance must be isolated from the gas
supply piping system by closing its individual
manual shut-off valve during any pressure
testing of the gas supply piping system at test
pressures equal to or less than 1/2 psig
(3.5kPa).
The appliance and its individual shut off valve
must be disconnected from the gas supply
piping system during any pressure testing of the
system at test pressures in excess of 1/2 psig
(3.5kPa.).
When checking the manifold gas pressure, the
inlet pressure to the regulator should be at least
6.0" W.C. for natural gas or 11.0" for propane.
Do not attempt any adjustment of the pressure
regulator.
Step 5: Electrical Requirements,
Connection and Grounding
CAUTION
Improper grounding or reverse polarization will
cause malfunction (such as continuous sparking
of the burner igniters). This can damage the
appliance and can create a condition of shock
hazard. If the circuit is not correctly grounded
and polarized, it is the responsibility and
obligation of the installer and user to have the
existing receptacle changed to a properly
grounded and polarized receptacle. This must
be accomplished in accordance with all
applicable local codes and ordinances by a
qualified electrician. In the absence of local
codes and ordinances, the receptacle
replacement shall be in accordance with the
National Electric Code. (See Figure 10.)
• Before installing, turn power OFF at the service panel.
Lock service panel to prevent power from being turned
ON accidentally.
• Always disconnect appliance from the electric supply
either by disconnecting power cord or shutting off the
breaker before servicing the appliance.
• Before you plug in an electrical cord, be sure all
controls are in the OFF position.
• All 120 Volt cooktop models must be plugged into a
mating 3-Prong, Grounding-Type Receptacle. The
receptacle must be connected to a properly grounded
and polarized electrical power supply rated at 120VAC,
Single Phase, 60HZ. See "Electrical Power Supply
Over-current Protection Requirements" on page 13 on
this page for proper over-current protection
requirements for each model.

• All 240 Volt cooktop models require hard wire
connections.
• 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 Figure 10 for
recommended grounding method.
• An electrical wiring diagram and schematic have been
attached to the bottom of the cooktop chassis for
access by a qualified service technician. Do not
remove or discard this important information.
Grounding Method for 120 VAC Models
The cooktop is factory equipped with a power supply cord
with a three-prong grounding plug (with polarized parallel
blades).
IT MUST BE PLUGGED INTO A MATING, GROUNDING
TYPE RECEPTACLE THAT IS CONNECTED TO A
CORRECTLY POLARIZED 120 VOLT CIRCUIT (240
VOLT CIRCUIT FOR MODELS WITH 24" ELECTRIC
GRIDDLE. (See Figure 10).

THE THIRD, GROUND PRONG MUST NOT BE CUT OR
REMOVED UNDER ANY CIRCUMSTANCES.
Electrical Connection for 240 VAC Models
1. Attach flexible conduit to the junction box.
2. Connect the cooktop lead wires to the junction box
supply wires in proper phase:
For all 240 VAC models, connect black (L1) to black,
red (L2) to red, white wire to neutral and green wire
to ground.
