11. Secure cables in place using tie-wraps or cable straps
according to electrical codes.
12. If applicable, route the optional battery temperature sensor
(BTS) from the battery (one which is located in the warmest
ambient temperature) to the charger location.
13. Additionally, you may connect DC 12V auxiliary devices
using a DC pos(+) cable and switching the DIP switch (next
to the Remote RJ45 port as shown in the figure) to either
DC or AC mode (see succeeding NOTE). Make sure to
connect the DC pos(+) cable to the DC+ Aux output
terminal on the battery charger. On the DC auxiliary device,
connect its DC neg(–) cable to the vehicle's common
Chassis ground bus.

IMPORTANT: The DC Aux terminal is connected to the BAT1
terminal thus its output voltage may change in conjunction with
BAT1 terminal output.
NOTE: DC auxiliary devices will operate whether AC power is
available or not if the DIP switch is set to DC mode. The DC
auxiliary devices will be powered by the charger while AC power is
also being applied to the charger. When AC power is not present,
the DC devices are powered from the battery. However, for normal
operation, the DIP switch should be set to AC mode, which means
DC auxiliary devices only work when AC power is available so as to
conserve battery power when AC power is unavailable.
NOTICE
EQUIPMENT DAMAGE
Do not use the DC+ Aux output terminal to connect to a battery for
charging. Connect only 12V DC-rated auxiliary devices. See DC
Aux output voltage on page 74.
Failure to follow these instructions can result in equipment
damage.
14. Proceed to Step 3: Installing AC Wiring.
