INTRODUCTION
The information provided in this manual covers single phase 15A, 20A, and 30A bypass distribution
modules, their basic functions, operating procedures, options available and emergency situations. It also
includes information on how to ship, store, handle, and install the equipment. Only detailed
requirements of the XBDM units are described herein, and installation must be carried out in
accordance with this manual. Refer to the associated UPS manual for UPS operating instructions.
Electrical installation must also carefully follow local legislation and regulations. Only qualified personnel
should conduct these installations as failure to acknowledge electrical hazards could prove to be fatal.
PRODUCT DESCRIPTION
Many different kinds of sensitive electrical equipment can be protected by an Uninterruptible Power
Supply (UPS) including computers, workstations, process control systems, telecommunications systems,
sales terminals, other critical instrumentation, etc. The purpose of the XBDM is to provide an extra level
of protection in allowing for the replacement of a UPS without powering down the loads connected. The
XBDM can work with most single phase topologies. It will not work with topologies that have a phase
shift between input and output (like ferro of UPS with an isolation transformer) .
Electrical interference exists in many forms, causing problems in AC power, from lightning, power
company accidents and radio transmission motors, air conditioners, and vending machines. Protection
of sensitive electrical equipment is vital to protect against power outages, low or high voltage
conditions, slow voltage fluctuations, frequency variations, differential and common-mode noise,
transients, etc.
To prevent power line problems from reaching critical systems causing damage to software, hardware,
and equipment malfunctions, the UPS maintains constant voltage, isolating critical load output and
cleaning the utility AC power. When a UPS fails or needs maintenance, many times it is necessary to turn
off the UPS and disconnect it from incoming electrical circuits. With the XBDM installed between the
incoming Utility and the UPS, you can replace the UPS and/or Batteries without dropping the load. You
simply switch the XBDM from UPS power to Utility power and remove the UPS while the load connected
to the XBDM continues to operate temporarily from Utility power.
Bypass Distribution Description
The Xtreme Bypass Distribution Module (XBDM) is designed to operate with a single-phase UPS up to
30Amps in output capacity. The XBDM allows you to:
•Replace or upgrade the UPS without losing power to the protected equipment
•Provide surge protection if the UPS is not present
•Provide extra surge protection when the UPS is present
