Bypass Distribuon Module
Thank you for selecng this bypass distribuon module. It is designed to work in conjuncon with a UPS to provide
you with protecon for connected equipment. Please read this manual before installing the XBDM as it provides
important informaon that should be followed during installaon allowing you to correctly set up your system for
the maximum safety and performance. Included is informaon on customer support and service. If you experience
a problem with the XBDM, please contact technical support.
WARNING: Incorrect installaon, operaon, and/or modicaons 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 Ulity power.
CAUTION! (UPS has Internal Baeries): Risk of electrical shock – Hazardous live parts inside the UPS are energized
from the baery 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 qualied service personnel.
WARNING! Unit intended for installaon in a controlled environment per installaon instrucons.
CAUTION! If ammable substances such as gases or fumes are present, or if the room is airght, a hazardous situ-
aon 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 qualied 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 baery
from the UPS may connue to supply power.
Care should be taken to undertake installaon indoors, free from electrically-conducve parcles 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
posion near the outlet where easily accessible.
All servicing on this equipment must be carried out by qualied service personnel.
The Xtreme Bypass Distribuon 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. Cauon 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 specicaons listed in
this document, otherwise the safety of installaon personnel cannot be guaranteed, and the unit may
malfuncon.
Ensure that you remember the following when locang the XBDM:
• Avoid extremes of temperature and humidity.
»Operang temperature: 0°C to +50°C (+32° to +122° F)
»Operang elevaon: 0 to 3000m (0-10,0000 )
»Relave humidity: 0-90%, non-condensing
»Storage temperature: 0-65° C (+32 to +149° F)
»Storage elevaon: 0 to 15,000m (0 to +50,000 )
• Provide protecon for the equipment from moisture.
• Space and venlaon requirements must be met.

Introducon
The informaon provided in this manual covers single phase 20A bypass distribuon module, its basic funcons,
operang procedures, opons available and emergency situaons. It also includes informaon on how to ship,
store, handle, and install the equipment. Only detailed requirements of the XBDM units are described herein, and
installaon must be carried out in accordance with this manual. Refer to the associated UPS manual for UPS oper-
ang instrucons. Electrical installaon must also carefully follow local legislaon and regulaons. Only qualied
personnel should conduct these installaons as failure to acknowledge electrical hazards could prove to be fatal.
Product Descripon
Many dierent kinds of sensive electrical equipment can be protected by an Uninterrupble Power Supply (UPS)
including computers, workstaons, process control systems, telecommunicaons systems, sales terminals, other
crical instrumentaon, etc. The purpose of the XBDM is to provide an extra level of protecon 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 isolaon transformer).
Electrical interference exists in many forms, causing problems in AC power, from lightning, power company ac-
cidents and radio transmission motors, air condioners, and vending machines. Protecon of sensive electrical
equipment is vital to protect against power outages, low or high voltage condions, slow voltage uctuaons,
frequency variaons, dierenal and common-mode noise, transients, etc.
To prevent power line problems from reaching crical systems causing damage to soware, hardware, and equip-
ment malfuncons, the UPS maintains constant voltage, isolang crical load output and cleaning the ulity 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 Ulity and the UPS, you can re-
place the UPS and/or Baeries without dropping the load. You simply switch the XBDM from UPS power to Ulity
power and remove the UPS while the load connected to the XBDM connues to operate temporarily from Ulity
power.
Bypass Distribuon Descripon
The Xtreme Bypass Distribuon 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 protecon if the UPS is not present
• Provide extra surge protecon when the UPS is present
As shown in the block diagram below:
• Under normal operaon, the UTILITY INPUT ows through the XBDM to the UPS and then out to the CON-
NECTED LOADS.

User’s Operaons
The purpose of this BYPASS DISTRIBUTION MODULE is to allow servicing of the UPS so as not to aect the LOADs
connected and protected. To transfer between UPS and ulity sources, swily actuate the bypass switch to the
opposite posion. Both the UPS, and Ulity lights available must be illuminated to prevent transferring to a non-
powered source.
Normal Operaon
When operang in NORMAL mode the switch on the front of the XBDM will be in the UPS posion
