5. Operating Voltage
The ILO Heater Panel is designed for use on 120VAC 60Hz and uses a standard Type B (NEMA 5 -
15P) plug for the North American market. See
Figure 5a
.
It features Line (Hot), Neutral and Earth
(Ground) pins. Outlets must have a proper
ground connection.
The power cord is approximately 6½ feet
(2.0m) long and is made from heat and
abrasion resistant PVC material.
The plug is molded to the cord and is not user
serviceable. If there is any damage or tears in
the cord insulation then it must be replaced by
a licensed electrician or returned to ILO North
America for repair/replacement.
Figure 5a
Type B Plug (NEMA 5 - 15P)
If a legacy 2 pin outlet (NEMA 1-15R) is the
only type of receptacle available, then a
polarized grounding adapter plug must be
used. It is essential that the grounding lug on
this adapter plug is screwed to the grounding
point on the outlet. As this type of adapter plug
is illegal in some jurisdictions (particularly
throughout Canada), a safer and more reliable
alternative identified in the US and Canadian
electrical codes is to replace the outlet with a
Ground Fault Circuit Interrupter (GFCI)
breaker outlet.
Figure 5b – Grounding Adapter Plug
The cord has a plug as shown at (A) in
Figure 5b
. An adapter as shown at (C) is available for
connecting three-blade grounding-type plugs to two-slot receptacles. The green grounding lug
extending from the adapter must be connected to a permanent ground such as a properly grounded
outlet box. The adapter should not be used if a three-slot grounded receptacle is available.
For enhanced security it is recommended to install an RCD (Residual Current Device) or GFCI
(preferably with a 30mA tripping point) in the electrical circuit. This will protect the user if there is
current leakage to earth.
