DANGER
HAZARDOUS VOLTAGE
(Can Cause Severe Injury or Death)
Turn OFF all power before installation, adjustment, or removal of transfer switch or any of its components.
ATTENTION!
This applies only to the switches with the RM4-CAT
exerciser option:
Only after ATS installation, connect a commercial-grade
alkaline 9V battery to the MX60 controller via the har-
ness connected to the controller. The battery should be
placed in the holder installed just above the controller.
The battery is used to maintain the exerciser function in
the event of power outage. The battery should be
replaced at least once a year. If the battery is not
installed and/or replaced as recommended, an
exerciser set from the front panel will lose its settings
during power outages and the exerciser will not work.
Note: Batter
y life if reduced if neither source is avail-
able. Typical battery life when both sources are
unavailable is 21 days.
Should the battery connection become disconnected
in shipping, take the controller cover off and plug the
harness into the receptacle in the top right corner of
the MX controller as shown in figure 2 and 5. Reinstall
the cover and connect the battery.
