Power cable entry to the heater should be made through one of
the knock-out holes located on the back plate or top/bottom
ends of the unit. Use the appropriate strain relief fitting.
The power leads are to be secured to the L1 and L2 or L and N
connectors on the terminal block or relay. The ground lead is to
be secured to the GND connector on the block or the green
ground wire with the provided wire nut.
FAILURE TO GROUND THE SYSTEM MAY RESULT IN SERIOUS INJURY, DEATH AND/OR PROPERTY
DAMAGE.
