NOTE
A jumper is factory installed between pins 1 & 2 to disable the Control Switch (SW2).
This will prevent the unit from being started during installation. This jumper must
be removed in order to start the unit.

CAUTION
To maintain safety, Signal Edge Low Voltage (SELV) barriers, and electromagnetic
compatibility, signal cables should be segregated and run separately from power cables.

Remove jumper before wiring.
If the installation does not
require connection to a REPO
system, the jumper must be
removed.
