Chapter 1 Introduction
The Maintenance Bypass Module (MBM) and Power Distribution Module (PDM) are
designed to work with an 8–15 kVA Powerware®9155 uninterruptible power system
(UPS). Both modules provide a Make-Before-Break (MBB) wrap-around bypass for
UPS maintenance or service without shutting down the load. The PDM also comes
equipped with several different types of output receptacles.
Safety Warnings
IMPORTANT SAFETY INSTRUCTIONS
SAVE THESE INSTRUCTIONS
This manual contains important instructions that you should follow during installation and maintenance of
the UPS and batteries. Please read all instructions before operating the equipment and save this manual for
future reference.
DANGER

Chapter 2 UPS-Mounted Bypass Switch Installation
This chapter describes the Maintenance Bypass Module (MBM) and Power
Distribution Module (PDM) installation. Both modules have a Make-Before-Break
(MBB) maintenance bypass switch.
NOTE If you are installing an optional isolation transformer with the MBM, refer to the Powerware 9155
UPS (8–15 kVA) User's Guide for installation instructions.
MBM/PDM Setup
If you purchased an optional MBM/PDM, attach the module to the UPS before any
wiring installation. All hardware is supplied in the accessory kit.
To attach the optional MBM/PDM to the UPS:
1. Remove the connecting plate between the top cabinet and the cabinet below it
on the UPS rear panel (see Figure 1). Discard the plate. Retain the screws for
later use.
2. Remove the lowest top cover screw on each side of the UPS and discard.

Wiring the MBM/PDM
The Powerware 9155 UPS has the following power connections:
S2‐phase (L1 and L2), neutral, and ground connection for rectifier/bypass input
S2‐phase (L1 and L2), neutral, and ground connection for load output
The nominal input/output voltages are:
S100/200, 110/220, or 120/240 Vac with 180°phase displacement
S120/208 or 127/220 Vac with 120°phase displacement
Output overcurrent protection and disconnect switch must be provided by others.
Figure 8 and Figure 9 beginning on page 12 show the oneline diagrams of the MBM
and PDM with the UPS.
WARNING
Only qualified service personnel (such as a licensed electrician) should perform the UPS installation and
initial startup. Risk of electrical shock.
To hardwire the MBM/PDM:
1. Verify that the electrical connections to the installation site have been properly
installed.
2. A wall-mounted, user‐supplied, readily‐accessible disconnection device must be
incorporated in the input wiring.
Compare the circuit breaker ratings and wire sizes to the specifications in Table 1
on page 10.
NOTE To accommodate the feature of easy system expandability, it is recommended that initial installation
of the Powerware 9155 UPS contain wiring to support the maximum capacity of the UPS cabinet.
3. Switch off utility power to the distribution point where the UPS will be
connected. Be absolutely sure there is no power.
4. Determine your equipment's grounding requirements according to your local
electrical code.
5. Verify that the UPS battery circuit breaker is in the OFF position (see Figure 5).

6. Punch two holes in the MBM/PDM conduit landing plate for the input and output
conduit using a Greenlee®punch or similar device.
7. Hardwire the input, output, and ground terminations for the MBM/PDM.
See Table 1 for specifications and Figure 6 for a detailed view of the MBM/PDM
terminal block.

NOTE Input neutral must be wired for proper operation. Failure to connect an input neutral will void the
warranty. However, when wired with the optional isolation transformer, input neutral is supplied by the
isolation transformer.
