Bypass Distribuon Module
Thank you for selecng this bypass distribuon module. It is designed to work in conjuncon with a UPS to provide
you with protecon for connected equipment. Please read this manual before installing the XBDM as it provides
important informaon that should be followed during installaon allowing you to correctly set up your system for
the maximum safety and performance. Included is informaon on customer support and service. If you experience
a problem with the XBDM, please contact technical support.
WARNING: Incorrect installaon, operaon, and/or modicaons made to the XBDM will void the manufactures
warranty. Lowell Manufacturing Co. is not liable for personnel or equipment damages as a result.

IMPORTANT SAFETY INSTRUCTIONS: (SAVE THESE INSTRUCTIONS)
CAUTION! Two sources of power are present in the XBDM: UPS power and Ulity power.
CAUTION! (UPS has Internal Baeries): Risk of electrical shock – Hazardous live parts inside the UPS are energized
from the baery supply even when the input AC power is disconnected.
CAUTION! (No User serviceable Parts): Risk of electrical shock, do not remove cover. No user serviceable parts
inside. Refer servicing to qualied service personnel.
WARNING! Unit intended for installaon in a controlled environment per installaon instrucons.
CAUTION! If ammable substances such as gases or fumes are present, or if the room is airght, a hazardous situ-
aon may exist in which no electrical equipment should be operated.
WARNING!
It is strongly recommended that the XBDM not be opened as components have very high voltage and
touching those components may be fatal. Only a qualied technician or authorized agent may service the
unit.
The XBDM unit’s output receptacles can carry live voltage even when not connected to an input voltage
source. The UPS has its own internal energy source.
CAUTION!
The unit has a dangerous amount of voltage. If either the UPS or BYPASS indicator is on, the unit’s outlets
may have a dangerous amount of voltage even when not plugged into the wall outlet because the baery
from the UPS may connue to supply power.
Care should be taken to undertake installaon indoors, free from electrically-conducve parcles which
are under temperature and humidity control, in order to reduce the risk of electric shock.
It is best to disconnect the device using the power supply cord. Ensure that the equipment is placed in a
posion near the outlet where easily accessible.
All servicing on this equipment must be carried out by qualied service personnel.
The Xtreme Bypass Distribuon Module (XBDM) is intended to allow replacement of the UPS connected
without having to shut down the equipment connected to the load circuits on the XBDM. Cauon should
be observed as the XBDM is always supplied with power by either the UPS or UTILITY.

Environment
Ensure that all environmental concerns and requirements are met according to specicaons listed in
this document, otherwise the safety of installaon personnel cannot be guaranteed, and the unit may
malfuncon.
Ensure that you remember the following when locang the XBDM:
• Avoid extremes of temperature and humidity.
»Operang temperature: 0°C to +50°C (+32° to +122° F)
»Operang elevaon: 0 to 3000m (0-10,0000 )
»Relave humidity: 0-90%, non-condensing
»Storage temperature: 0-65° C (+32 to +149° F)
»Storage elevaon: 0 to 15,000m (0 to +50,000 )
• Provide protecon for the equipment from moisture.
• Space and venlaon requirements must be met.

Introducon
The informaon provided in this manual covers single phase 20A bypass distribuon module, its basic funcons,
operang procedures, opons available and emergency situaons. It also includes informaon on how to ship,
store, handle, and install the equipment. Only detailed requirements of the XBDM units are described herein, and
installaon must be carried out in accordance with this manual. Refer to the associated UPS manual for UPS oper-
ang instrucons. Electrical installaon must also carefully follow local legislaon and regulaons. Only qualied
personnel should conduct these installaons as failure to acknowledge electrical hazards could prove to be fatal.
Product Descripon
Many dierent kinds of sensive electrical equipment can be protected by an Uninterrupble Power Supply (UPS)
including computers, workstaons, process control systems, telecommunicaons systems, sales terminals, other
crical instrumentaon, etc. The purpose of the XBDM is to provide an extra level of protecon 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 shi between input and output (like ferro of UPS
with an isolaon transformer).
Electrical interference exists in many forms, causing problems in AC power, from lightning, power company ac-
cidents and radio transmission motors, air condioners, and vending machines. Protecon of sensive electrical
equipment is vital to protect against power outages, low or high voltage condions, slow voltage uctuaons,
frequency variaons, dierenal and common-mode noise, transients, etc.
To prevent power line problems from reaching crical systems causing damage to soware, hardware, and equip-
ment malfuncons, the UPS maintains constant voltage, isolang crical load output and cleaning the ulity AC
power. When a UPS fails or needs maintenance, many mes it is necessary to turn o the UPS and disconnect it
from incoming electrical circuits. With the XBDM installed between the incoming Ulity and the UPS, you can re-
place the UPS and/or Baeries without dropping the load. You simply switch the XBDM from UPS power to Ulity
power and remove the UPS while the load connected to the XBDM connues to operate temporarily from Ulity
power.
Bypass Distribuon Descripon
The Xtreme Bypass Distribuon Module (XBDM) is designed to operate with a single-phase UPS up to 20Amps in
output capacity. The XBDM allows you to:
• Replace or upgrade the UPS without losing power to the protected equipment
• Provide surge protecon if the UPS is not present
• Provide extra surge protecon when the UPS is present
As shown in the block diagram below:
• Under normal operaon, the UTILITY INPUT ows through the XBDM to the UPS and then out to the CON-
NECTED LOADS.

LED Descripon
The XBDM has three LED’s on the front control panel. These LED’s allow the user to quickly understand the status
of the unit.
Red LED = UPS power is available
Orange LED = Ulity is available for Bypass operaon
Green LED = Surge Protecon is available.
XBDM Front Panel LED’s
CAUTION: The Orange LED must be illuminated before transferring to BYPASS power.
The Red LED must be illuminated before transferring to UPS power.
