Installing a Battery Heater
For colder climates, Calix recommends using an optional battery heater to prevent batteries
from freezing and to prolong battery life. The cabinet supports up to three battery heaters,
with each heater supporting two battery strings (front to back). The battery heater is
controlled by a thermostat set for the following operation:
0° C
– Battery heater turns On.
12° C
– Battery heater turns Off.
Note:
Battery heaters sit directly underneath the battery strings. Install heaters into the
battery compartment before installing batteries.
To install a battery heater
1.
Unpack the battery heater from the shipping packaging.
2.
Remove the front battery compartment door. See
Operating Cabinet Doors
) for
instructions.
3.
Facing the front battery compartment, orient the battery heater with the heating element
on the bottom (face down) and the power cord on the right side, then slide the heater
into the battery compartment.
4.
Route the power cord to the AC outlet (located on the right inside wall of the battery
compartment) and plug the cord into the outlet.
Note:
For heaters in the left and center bays, plug the heater power cord into an
extension cord (included in the installation kit), then plug the extension cord into the AC
outlet.
5.
After the batteries are installed, place the thermostat wire for the heater on top of the
battery string. See Installing Batteries for installation instructions.
6.
At the AC load center, switch the 20A Convenience Outlet breaker
ON
to apply power.
