Notes
:
• All models use 120VAC 60 Hz or 240V~ 50 Hz control circuits.
• 208V, 240V and 400V models supply 120V (OR 240V to control circuit internally, 480V models require a separate 120V service.
o For 208V, 240V and 415V models, run power wires + Ground and a 14AWG Neutral for controls.
o For 480VAC units, run 3 power wires + Ground and run a 120V service for the control circuit.
• All models: no internal heating circuit fuses are needed; a panel mounted 3A fuse provided for the control circuit
• Use only copper wire, rated 75°C or better.
• Install all wiring per local and national codes.
