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.

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.
UPS-MOUNTED BYPASS SWITCH INSTALLATION 3. Attach the supplied L-bracket to the lower rear (for 2-high) or middle rear (for 3-high) cabinet using three screws (see Figure 2). Repeat for the other side. 4. Remove the UPS wiring access cover and retain. UPS Wiring Access Cover L-Bracket and Screws Figure 2. Attaching the L-Brackets 5. Remove the MBM/PDM wiring access cover and one of the conduit landing plates and retain. 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. TB10 Figure 6.
UPS-MOUNTED BYPASS SWITCH INSTALLATION 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. Table 1.

Chapter 3 Maintenance Bypass Switch Operation This chapter describes: S Startup in Maintenance Bypass mode S Transferring the load to maintenance bypass S Returning the load to Normal mode The UPS-mounted maintenance bypass switch is part of the Maintenance Bypass Module (MBM) or Power Distribution Module (PDM) and is located on the back of the UPS (see Figure 10). Figure 10. Maintenance Bypass Switch (PDM Shown) The UPS-mounted bypass switch has three positions as described in Table 2.
MAINTENANCE BYPASS SWITCH OPERATION UPS-Mounted Bypass Switch Bypass User-Supplied Service Building Service Panel UPS Load Distribution Panel Bypass Service UPS Bypass Service UPS UPS EBM Figure 11. Typical Hardwired Installation with UPS-Mounted Bypass Switch Maintenance Bypass Startup To start the UPS in maintenance bypass: 1. Verify that the maintenance bypass switch is in the BYPASS position (see Figure 10). 2. Switch on utility power where the UPS is connected.
MAINTENANCE BYPASS SWITCH OPERATION Transferring the Load to Maintenance Bypass To transfer the load from the UPS to maintenance bypass: 1. Turn the maintenance bypass switch through the SERVICE position to the BYPASS position. The UPS battery circuit breaker trips, and the UPS is now bypassed, with the load powered by utility power. 2. The UPS automatically shuts down. Returning the Load to Normal Mode To transfer the load from maintenance bypass to the UPS: 1.
