Electrical Installation
8.1
Incoming Power 115/230 VAC
The controller can be powered from either 115 VAC or 230 VAC at 50/60 Hz. The controller comes with
a power cord and receptacles. The power cord and receptacles are rated for 115VAC. If the controller
will be powered by 230 VAC, the power cord and receptacles will need to be removed and the incoming
power and the relay outputs will need to be hard-wired.
The incoming power is connected to terminal block TA at the bottom right corner of the power supply
board. There is a hot or line input (terminal 4), a neutral input (terminals 2 and 3) and an earth ground
input (terminal 1). The hot is wired to the fuse holder located on the bottom of the enclosure. The
neutrals are wired directly to terminals 2 and 3 of terminal block TA. Refer to the drawing in the back of
this manual for wiring instructions.
8.2
Relay Outputs
The relay outputs are of the same voltage as the power input. Ensure that the devices that are to be
connected to the relay outputs are of the same voltage rating or damage will occur.
The relay outputs are wired to the receptacles. The receptacle on the far left is relay #1 and the
receptacle on the far right is relay #4. On the power supply board, relay #4 is on the far left and relay #1
is on the far right. If 115 VAC is used simply plug your devices into the molded receptacles. If 230 VAC
is used, remove the receptacles and hard-wire your devices to the relay outputs.
