WIRING INFORMATION
IMPORTANT INFORMATION: READ BEFORE CONNECTING TO POWER SUPPLY
1. Disconnect branch circuit or power supply before connecting or servicing.
2. All wiring must be done in accordance with the N.E.C./C.E.C., or local code having jurisdiction.
3. Do not cover face of heater at any time with an object, other construction or furnishing as over heating could result and
combustion of objects.
4. Check to determine that branch circuit voltage is the same as voltage shown on panel data label. Do not connect to
a circuit having a higher voltage as a hazard can result. Connecting to a lower voltage will result in a lower operating
wattage.
NOTE:
1. The 120 and 240 volt panels are furnished as dual rated 120/240 volt units. The operating volts determines which leads
are to be connected. See Fig. 3
A. For 240 volt connection the two black leads are connected to the eld power supply. The white lead is not used and is
to be insulated by wrapping tape over the open conductor.
B. For 120 volt connection the two black leads are to be spliced together and connected to the black eld power supply
conductor. The white lead is to be connected to the white eld power supply conductor.
C.. Grounding: Connect the eld supply grounding conductor to the panel ground conductor (green).
2. The 208 Volt panels are furnished as single rated units and have two black leads to be connected to the eld supply
power leads in the junction box. Reference Fig. 1 for grounding connection.
3. The 277 volt panels are furnished as single rated units and have one black and one white lead to be connected to the
eld supply power. The black lead must be connected to the black eld power supply lead and the white panel lead
must be connected to the white power supply lead. The single pole thermostat must be connected to the black power
supply lead. Reference Fig. 2 for grounding connection.
OPERATION
1. Turn on the power supply to heater.
2. Rotate thermostat knob fully clockwise.
3. Allow the room to reach desired temperature, then rotate thermostat
knobcounter clockwise until the heater de-energizes.
4. For remote thermostat operation, thermostat wiring must be the same size
as power supply wiring.
