Section 9, Installing the Distribution Module
9-10 The POLAR™HD Heating Module
• 12 pin connector to Distribution Module (connector cord
transitions to a 9 pin connector for the Distribution Module).
• 14 pin connector to thermostat and cabin fan connector
plug.
Cabin Fan leads
• The positive (red) lead from each cabin fan is to be
attached to one of the trailing cabin fan leads, color coded for
zones, from the thermostat and cabin fan connector plug.
• The negative lead from each cabin fan is to be attached to a
ground terminal (not provided) that is connected to a battery
ground.
• The cabin fan 1 leads (orange) can supply up to a maximum
of 10 Amps. The other cabin fan leads 2-5 can supply up to a
maximum of 5 Amps each. The total current draw is not to
exceed 18 Amps for all cabin fan leads.
• If the system requires higher amperage draws, install a
separate relay to power the fans. This relay will use the
existing fan circuit as a signal and must be wired to a
secondary power source (not the heater’s control board). See
Figure 5-3.
Thermostat Leads
• The power lead to the thermostat is to be attached to a
power terminal (not provided) that is connected to the
battery.
• The return lead from each thermostat is to be attached to
one of the trailing thermostat leads, color coded for zones,
from the thermostat and cabin fan connector plug.
