Preparing the Site
For the MBM to operate at peak efficiency, the installation site should meet the
environmental parameters outlined in the PowerwareÒ 9315 Operation manual
provided with the UPS system. The operating environment must meet the size and
weight requirements supplied in the PowerwareÒ 9315 Installation manual provided
with the UPS system. If the MBM is to be operated at an altitude higher than 1500
meters (5000 feet), contact the local sales or service office for important information
about high altitude operation.
The basic environmental requirements for operation of the MBM are:
Ambient Temperature Range 0---40˚C (32---104˚F)
Recommended Operating Range 20---25˚C (68---77˚F)
Maximum Relative Humidity
95%
The MBM uses convection cooling to regulate internal component temperature. Air
inlets are in the front of the cabinet, and outlets are in the top. Clearance in front of
and above each cabinet for proper air circulation is essential.
Creating an Installation Plan
Before beginning to install the MBM, read and understand how this manual applies
to the system being installed. It is important to note that UPS module installation
procedures are contained in the PowerwareÒ 9315 Installation manual provided
with the UPS system. It is recommended to first understand how to install the UPS
modules. The information in Chapter 2 of this manual is a guide for installation of
the MBM to the UPS modules.
Environmental Considerations
The life of the maintenance bypass module is adversely affected if the installation
does not meet the following guidelines:
1. The MBM must be installed on a sealed concrete pad or floor.
2. The MBM must be installed in a dust-free environment.
3. The MBM must be installed in a humidity-controlled environment.
Preparing for Wiring the Maintenance Bypass Module
See Tables A-1 through A-6 in Appendix A of this manual for wiring requirements.
The power wiring for this equipment is rated at 90_C. If wire is run in an ambient
temperature greater than 30_C, higher temperature rating and/or larger size wire
may be necessary. Wiring should be installed through the bottom or top entry of
the module. For UPS external wiring requirements, including minimum AWG size
of external wiring, see the PowerwareÒ 9315 Installation manual provided with the
UPS system.
NOTE: Material and labor for external wiring are to be provided by designated
personnel.
