Page 3: I) Overview
OVERVIEW The PM Series Power Module is a uniquely adaptable communication equipment power source which functions as either power supply or battery charger for 12, 24 or 48 volt d.c. systems positive, negative or floating ground. Power Modules may be employed singly or in combination, enabling the installer to scale the system output from 560 to 6,000 watts per rack. -
Page 4: B) Emi (Electro-Magnetic Interference)
INSTALLATION Two notes regarding nomenclature used in this manual 1) For the sake of brevity the PM Series Power Module is referred to simply as the PM (meaning all models, generically). 2) Where installation differences exist, reference is made to 560 watt or 1,000 watt models. -
Page 5: A) Materials Provided
560 watt models refers to: PM-12-40 PM-24-20 PM-48-10 1,000 watt models refers to: PM-12-70 PM-24-35 PM-48-18 Note: This section covers only mounting, input and output wiring. Two installation options, Remote Shutdown wiring and Local/Remote Alarm wiring, are covered in those sections in the OPERATION portion of this manual. -
Page 6: C) A.c. Input Wiring And Voltage Selection
C) a.c. Input Wiring and Voltage Selection 1) 560 Watt Models Only Input Wiring: These models are provided with an IEC power cord (in the installation kit) with a NEMA 5-15 plug for a 115V a.c. outlet on one end and a molded socket at the other which fits the entry module at the rear of the PM. - Page 7 FIGURE 4: a.c.

Page 8: D) D.c. Output Wiring
D) d.c. Output Wiring Important: Ensure that a.c. input to the PM is switched off before working with d.c. wiring. The output terminals are “hot” whenever the unit is switched on. 1) Output terminals for hard-wiring of DC output are located on the rear panel of the PM. Termi- nate wires with 1/4"... - Page 9 Note: 1kW models illustrated here; refer to Figure 2 for output terminal positions of 560 watt models FIGURE 5: Single Power Module, negative ground, with battery: Typical; Fuse per N.E.C. or local codes (+) Positive to Load or Distribution Panel BATTERY (-) Negative to Load or Ground Bus Bar...

Page 10: E) Parallel Wiring
E) Parallel Wiring The internal oring/isolation diode of the PM allows parallel n+1 redundant wiring with no modification or other external isolation devices required. Figures 9-10 on the following page illustrate some typical parallel wiring schemes. Important: When wiring two or more units in parallel d.c. wires for all units should be identical in gauge and length and the output voltage of each module should be adjusted (as outlined below) in order to facilitate droop load sharing. - Page 11 Note: 1kW models illustrated here; refer to Figure 2 for output terminal positions of 560 watt models FIGURE 9: Parallel (two to six Power Modules) and N+1 redundancy, negative ground PM # 1 (+) Positive to Distribution Panel or Battery (fuse at battery per PM # 2 N.E.C.

Page 12: F) Chassis Grounding
F) Chassis Grounding If grounding of the PM chassis is required for the installation, use the provided 1/4" grounding stud on the rear panel for this purpose (see Figure 2 or 3). OPERATION A) a.c. Input The PM will operate on either 115 or 230 VAC (+15% to -25%) input at 50-60 Hz. Input voltage selection is explained in the INSTALLATION section. -

If the fan fails to operate when the PM is turned on and a load is applied, it may need to be re- placed. (Replacement fans available from NEWMAR. Specify part number 999-1208-0, Replace- ment Fan with PCB connector.) -

2) Feed the (+) and (-) TTL signal wires through the wiring access port on the rear of the unit. 3) On the main printed circuit board, locate terminals J3 and J6 near the front of the unit. (Further identified as “SHUTDOWN” on 560 watt models only.) FIGURE 11: PCB Locations of J3 and J6 560 Watt Models 1,000 Watt Models... -

A color-coded wire “pigtail” with keyed plug is provided for wiring convenience and to assure proper connections. The plug holds three wires for the output fail relay. The alarm may be wired with the relay “normally open” or “normally closed”, as needed. The position of the contacts during d.c. -

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 installa- tion. -
