7.0 – INSTALLATION
Multiple mounting methods and cage-clamp
terminals make installation simple and fast.
7.1 – Location
Enclosures used for mounting should be ventilated
to prevent heat build-up. Do not mount the EP, or
the system battery, in direct sunlight, in
corrosive environments, or near generators or
other sources of extreme heat.
The EP senses the air temperature and adjusts the
battery's charge voltage. Because of this, the unit
should be located close to the battery to sense the
battery's temperature. For enclosure applications,
mount the unit about 6" or less above the battery.
For indoor applications mount the unit in the same
room, over the battery.
7.2 – Mounting
The EP can be mounted on flat panels or standard
35mm DIN rails. For proper ventilation, the unit
should be mounted in a vertical position, with the
label vertical and the text horizontal. As shown in
the figures below, at least 1" of clearance should be
allowed above and below the unit for airflow. Do not
block the ventilation holes on the top, back, and
bottom of the unit.
To mount the unit on a flat panel, drill holes and use
#8 screws to secure. See Fig. 7.2.1 below for
dimensions.
Figure 7.2.1 – Flat Panel Mounting
To mount the unit on DIN rail, place the unit in
position with the mounting tabs nested inside the
DIN rail, snap 2 standard end-stops over the rail and
tighten the screw. There are 2 positions possible
with DIN-style mounting, high and low. See Figs.
7.2.2 & 7.2.3 for dimensions.
Figure 7.2.2 – High Position DIN Mounting.
Figure 7.2.3 – Low Position DIN Mounting.
7.3 – Wiring

guidelines when wiring this device.
Stranded wire is recommended for all connections in
the UPS system. The following wire sizes are
recommended:
Line / Input Wiring – 12-14 AWG
