11.5 Electrical connection

WARNING Electrocution
- Carry out all electrical connection and installation
work in accordance with relevant regulations.
- The heater must be able to be separated from the
power supply by an isolator that disconnects all
poles with at least 1/8˝ (3 mm) contact separation.
Material losses
- Observe the type plate. The specified voltage must
match the mains voltage.
- Ensure the on-site power supply cable is of an ade-
quate gauge to meet all applicable codes.

120 V hard-wired connection to a circuit breaker
Trim the power cable by cutting off the plug.
Connect the trimmed end of the power cable to a suitable
appliance junction box.
The appliance junction box must be connected to a circuit
breaker of suitable size. See section 15.2, "Data table", pg.
13.

Install a ½˝ ROMEX clamp in the knockout of the junction box
at the rear of the unit to prevent the power cable from being

pulled out of the wiring block during operation.
Cable must be routed from a circuit breaker of suitable size,
through the ROMEX clamp, and connected using the wire
nuts in the junction box of the unit. See section 15.3, "Wiring
diagrams", pg. 13.
Alternatively, the installer may remove the supplied wires
with nuts from the heater's wiring block, run wire of a suit-
able gauge through the installed ½˝ ROMEX clamp, and con-
nect the wire ends directly to the heater's wiring block. See
section 15.3, "Wiring diagrams", pg. 13.
Ensure the circuit breaker is a suitable size and the power cable
is a suitable gauge. See section 15.2, "Data table", pg. 13 for
electrical requirements.
11.5.3 Wiring block
Consult the chart below for the recommended torque amounts on
the wiring block screws.
Screw Size (mm)
M3.5
Using the proper torque specifications to secure wire to the wiring
block helps to avoid personal loss or property damage.
12. Commissioning
The heater is ready for operation as soon as it has been mounted
to the installation wall and connected to the power supply.
Remove the protective film from the programming unit.

13. Troubleshooting

The power cable must only be replaced (for example if damaged)
by a qualified contractor authorized by the manufacturer, using
an original spare part.
Material losses
- Trim the power cable so it leads directly to the heat-
er connection socket.
- Ensure that, after trimming the power cable, the
heater can still be removed from the wall without
issue.
