POWER CONNECTION
Line voltage connection is made by connecting the incoming
line voltage wires to the “L” side of the contactor as shown in
Figure 21. Consult Tables 5a and 5b for correct fuse size.
208 VOLT OPERATION
All residential 208-230 Volt units are factory wired for 230
Volt operation. The transformer may be switched to the 208V
tap as illustrated on the wiring diagram by switching the red
(208V) and the orange (230V) wires at the contactor terminal.
ACCESSORY CONNECTIONS
A terminal paralleling the compressor contactor coil has been
provided on the DXM2.5 control. Terminal “A” is designed
to control accessory devices.
NOTE: This terminal should
be used only with 24 Volt signals and not line voltage.
Terminal “A” is energized with the compressor contactor
(see Figure 26).
The DXM2.5 controller includes two accessory relays ACC1
and ACC2. Each relay includes a normally open (NO) and
a normally closed (NC) contact. Accessory relays may be
configured to operate as shown in Tables 6 and 7.
