Installation
Connect the load wiring as follows:
1. Unplug the Model 5420 from the power source.
2. Remove the 4 screws that secure the cover to the base.
2 of the screws are on the back of the 5420 where the cord
exits the base and the other 2 are on the bottom next to the
front feet.
3. Carefully lift the cover up and tilt toward the front of the
unit. Note: There are wires that connect the components on
the cover to the components on the base.
4. Strip the insulation back on the heater wires ¼ inch.
5. Insert the wire from the heater through the strain relief.
6. Connect the heater wires to the LOAD CONNECTION
terminal block. Many of Research Inc. heaters use a High
Temperature Teflon wire that gets connected as follows:
Black – L1
White – L2
Red - GND
7. Finish the installation by tightening the strain relief around
the heater wires and installing the cover back on the base
with the 4 screws. DO NOT OPERATE WITHOUT
COVER PROPERLY INSTALLED.
