Note:
Many items should be considered with remote control applications. Refer to
the Best Practices for Remote Control document.
Wire the auxiliary output to common on the output relay. Wire the coil positive
terminal on the interposing relay to normally open or normally closed on the output
relay. Wire the negative coil terminal to Aux (-).
8. Install the 120 VAC transformer and wire AC power. Slip ferrite core over the two
conductors going to the AC in connection (see Figure 4B). Mount the transformer in
the control panel (not the Mission RTU).
It is very important to only provide 12–16 VAC to the Mission mainboard AC input.
Hooking up the transformer backwards will apply 1200 VAC to the mainboard and
cause permanent damage. Do not install transformer in the RTU. Install it in the
control cabinet.
Warning:
Connect AC power to the primary input (black wires). Connect the
secondary output (red wires) to the mainboard input. The transformer steps the
power down from 120 VAC to 12 VAC. Do not turn on station AC power at this
time.
