Step 5: Electrical Requirements, Connection And Grounding - Thermador P24GE Installation Instructions Manual

CAUTION
: Improper
g r o u n d i n g o r r e v e r s e
polarization will cause
m a l f u n c t i o n ( s u c h a s
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 Fig.10.)
• Before installing, turn power
OFF at the service panel. Lock
service panel to prevent power
from being turned ON acci-
dentally.
• 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 electri-
cal 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 list on
this page for proper over-current
protection requirements for each
model.
• All 240 Volt cooktop models
require hard wire connections.
Step 5: Electrical Requirements,
Connection and Grounding
• 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 Fig. 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

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.
Note: If the 120V cooktop is install-
ed and connected as specified
above, it will be completely
grounded in compliance with the
National Electric Code.
3. Turn on power supply.
4. Test operation.
