Restore to Factory Settings: The ULM-100 comes with default factory settings that will work for most applications.
This feature will clear all user setting changes back to factory settings. This is particularly useful in the event the ULM-
100 contactor begins cycling. Example: Connect and Disconnect thresholds set too close toghether. The ‘Restore Setting’
feature can be activated in the settings menu.
5.3
Battery Circuit Breaker: The Hot side of the battery input goes to a front panel mounted 100 Amp circuit breaker
labeled ‘BATTERY’. This circuit breaker incorporates auxiliary contacts which will alert the user via the LCD display (‘Battery
offline’) and red ‘Alarm’ LED, should the breaker trip or be placed in to the OFF position inadvertently.
5.4
Alarm LED: This red LED will illuminate when any of the following conditions occur:
• Battery circuit breaker in OFF position
• LVD Pre-disconnect threshold crossed (see section 5.13 for more info)
• LVD activation- manually or automatically
6.0 Connecting Rectifier Types
The ULM-100 will accept any filtered rectifier input (s) providing total rectifier amperage does not exceed 100 Amps. See
Figure 5 and 6 for wiring examples of Newmar Unity Rectifier Shelf (URS) and Power Modules (PM Series).
6.1
Unity Rectifier Shelf (URS): The URS has two sets of output terminals. Both are marked ‘OUTPUT/BATTERY’. One set uses
a barrier style terminal block with # 6 screw terminals located near the optional UFP-5 fuse panel location and the other
is a european style terminal block on the opposite end of URS rear panel which will accommodate up to 8 AWG wire size.
The ULM-100 Rectifier Input can be connected to either one of these two sets of output terminals.
UFP-5 Note:
If using the optional Unity UFP-5 GMT Fuse Distribution Panel, the UFP-5 Hot & RTN/GND input leads will have
to be extended with a pair of 14 AWG wires and crimp butt connectors. Connect extended UFP-5 input wires to the ULM-
100 LOAD terminals.

6.2
Power Module (PM Series): One or more Newmar PM Series Power Modules can be connected to the ULM-100 Rectifier
Input (100 Amps max. total). Use the ‘Vout’ or diode isolated terminal when connecting 2 or more PM’s in parallel. Figure
6, ULM-100 and Power Module wiring diagram - next page.
