WIRING GUIDE – OIL (NWHOSR)
Directions:
Step 1: Select the PCN number below which matches the PCN number on your heater.
Step 2: Choose your kW, Volts, phase, and number of circuits under your PCN number
(you must know the kW and watt density
(watts/sq. in.) needs for your application)
.
Step 3: Note the Wiring diagram # for your selection.
Step 4: Go to Wiring Diagram sheet. Peel off the diagram that matches the # in step 3. Stick this to the inside of your electrical enclosure.*
Step 5: Peel off corresponding Volts, circuit-phase, and kW info from the Wiring Diagram sheet and stick to the designated spot on the
nameplate. (These labels will cover the maximum rating stamped on the nameplate.)**
Step 6: Wire Heater according to the sticker on the inside of your electrical enclosure (from step 4).
