Tools Needed For Installation
•
Power drill and suitable drill bit
•
Phillips and flat head screwdrivers
•
Mounting screws or wall anchors
•
Electrical materials
•
Voltmeter to indicate voltage presence
NOTE: Use the Digital Multimeter (DMM) LowZ low input
impedance setting to collect accurate voltage measure-
ments. LowZ eliminates the possibility of inaccurate
ghost voltage readings, also known as phantom voltage
or stray voltage readings. See DMM manufacturer's liter-
ature for additional information.

Mounting Instructions
DANGER
Electrocution. Turn utility and emergency
power supplies to OFF before connecting
power source and load lines. Failure to do so
will result in death or serious injury.
Recommended installation is near the electrical panel or
appliance/load. The enclosure has a NEMA 3R rating
and can be mounted indoors or outdoors. It provides a
degree of protection against rain and sleet and is
undamaged by the formation of ice on the enclosure.
1. Turn off both UTILITY (NORMAL) and EMER-
GENCY (STANDBY) power supplies.
2. Select mounting location (near electrical panel,
appliance, or load to be managed).
3. See
Figure
2-1. Hold SMM enclosure against
mounting surface with arrows (G) pointing up, and
mark or drill four mounting holes (F). See
1
for mounting dimensions if necessary.
