WARNING
HAZARDOUS VOLTAGE: Risk of electric shock. Can cause injury or death. Heater may be connected to more than one branch circuit. Disconnect power to all circuits before servicing.
De-energize System
Disconnect power to all branch circuits of the heating system and remove electrical panel cover.
Loosen Lug Screws
Locate the circuit breakers and loosen all lug screws.
Install Neutral Lug
Remove the existing neutral lug and install the neutral lug provided.
Install Rear Single Feed Plate
Locate rear single feed plate (with insulator) and install as follows:
-
Model 5120 - Insert the right leg of the rear single feed plate into the right lug of the third 60-amp breaker. The other legs on the plate will fit into place on the remaining breakers.
-
Model 5130/5140 - Insert the left leg of the rear single feed plate into the left lug of the 15-amp breaker. The other legs on the plate will fit into place on the remaining breakers.
NOTE: Do NOT remove insulator from rear single feed plate. This insulator protects the circuit from shorting.
Install Single Feed Plate
Locate front single feed plate (no insulator) and install as follows:
-
Model 5120 - Insert the left leg of the front single feed plate into the left lug of the 15-amp breaker. The other legs on the plate will fit into place on the remaining breakers.
-
Model 5130/5140 - Insert the far left leg of the front single feed plate into the right lug of the 15 amp breaker. The other legs on the plate will fit into place on the 60-amp breakers.
Verify Both Single Feed Plates are Seated
Make sure both single feed plates are seated into the lugs. Tighten down all lug screws.
Install one Leg of Power
Install one leg of the main power source wires into each of the top lugs of single feed plates.
Wire the Ground
Wire the ground lead into the ground lug.
Inspect Uninsulated Terminals
Visually inspect all uninsulated live terminals to ensure there is no potential line-to-line and/or line-to-ground short circuits.
Install Electrical Panel Cover
Install electrical panel cover and restore power to the heating system.
