the fan air flow is toward the rear of the PM (arrow on body of fan
pointing to the rear)
7. Connect the replacement fan's connector to the mating
connector on the main circuit board and re-attach the fan
mounting plate to the long air baffle plate.
8. Replace the PM's top cover, reconnect ac power and verify
replacement fan operates.
D) Indicators and Alarms
"On" Indicator light-Indicates ac input breaker is in the On position
and that ac input voltage is present.
System Status LED, Audible alarms and form C alarm contact -
See chart on page 7.
E) Remote Alarm
Form C alarm contacts are provided for AC input and DC
output fail.
A color-coded wire "pigtail" with keyed plug is provided for wiring
convenience and to assure proper connections. The plug holds six
wires: three for the DC output and three for the AC fail relays.
The alarm may be wired with the relay "normally open" or
"normally closed", as needed. The position of the contacts during
failure and normal operating condition is illustrated below:

A) Temperature Compensation Option
Because low battery temperature increases resistance to charging
and high battery temperature reduces impedance, requiring a
lower charge voltage, the ideal charging voltage will vary

depending on the temperature of the battery's environment when it
is being charged. The remote sensor will signal the PM to fine tune
its output voltage so that it is properly matched to the temperature
of the battery/battery environment. Specify Model "TP" when
ordering.
The PM will compensate PM output voltage up or down from
the factory default of 27.2 v (24 v model) or 54.4 v (48 v model)
at 30ºC by -120mV per ºC (48 v model) or -60 mV per ºC (24 v
model). If the battery reaches +50ºC the PM will turn itself off. The
PM will automatically restart once the battery temperature drops
approximately 5-10ºC.
Temperature Probe (model TP) Installation
1. Disconnect ac input power and dc output connections to the
PM. If a battery string is connected it is recommended that it be
disconnected (via battery disconnect switch or remove the HOT
lead from the battery).
2. Remove TP access plate (4 screws). Thread TP sensor end through
belly-button grommet.
3. Plug the TP connector into the mating 5 pin connector on the
small circuit board directly inside access hole. Replace access
panel (4 screws). The connector is keyed and will fit in one
direction only.
4. The cylindrical probe sensor end can be placed between battery
cases or attached to the top of one of the batteries using some RTV
silicone.
B) D.C. Quick Connect Wiring Kit
Note: This option is available only for systems which incorporate the
NEWMAR Power Function Manager Model PFM-400. For complete
information on this product, please contact the factory.
A d.c. wiring harness quick connect kit model CCK-4 is available
from NEWMAR which simplifies parallel wiring installation of
multiple Power Modules with the Power Function Manager and
facilitates "hot change-out" of modules for repair or replacement.
The kit consists of two wiring harness; one for positive and negative
d.c. output wiring, another for alarm contact wiring. Wires are pre-
cut to proper length, all necessary connectors are installed and the
bundles are neatly tie-wrapped into proper position for a simple
and professional installation.
