CAUTION! Remove the RED protection cap only for ½ NPT conduit installation. Never
remove the adapter.
CP heaters must be installed with a thermostat to avoid damage to the heater.
The heater must only be connected and secured by certified technical personnel in
accordance with the label specifications, rated voltage and rated current:
If operating voltage equals rated voltage, the heater will generate the specified nominal
output, with an allowance to voltage fluctuations of up to 10%.
Circuit breakers suitable for up to 16 amps can be used for short circuit and line
protection.
A ground terminal is provided for the purpose of ensuring potential equalization. The
terminal is marked as such.
In a TT or TN system, a residual current operated protective device (RCD) must be used
with a rated response fault current not exceeding 100 mA. Residual current devices with
a rated response fault current of 30 mA are preferred.
When installing for an IT system application, an insulation monitor must be used that
switch off the power supply as soon as the insulation resistance falls to 50 ohms per volt
of the rated voltage or lower (see DIN EN 60079-14:2008; section 7.4).
OPERATION
Turn on the heater once properly installed. A safety fuse will permanently open the
circuit if improperly installed.
