Thank you for selecng the UPS-XBDM-20RHW bypass distribuon module. It is designed to work in conjuncon
with a UPS to provide protecon for connected equipment. Please read this manual before installing the UPS-
XBDM-20RHW as it provides important informaon that should be followed during installaon to allow you to
correctly set up your system for 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 manufacturer’s
warranty. Lowell Manufacturing Company 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.
For indoor use in temperature and humidity-controlled environments only.
Not for use where explosive and/or electrically conducve airborne contaminants or dust are present
(including but not limited to coal dust, metal grinding dust, grain processing dust, etc.).
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 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 ob-
served 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 hardwired 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 unit are described
herein, and installaon must be carried out in accordance with this manual. Refer to the associated UPS manual for
UPS opera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, a UPS maintains constant voltage, isolang crical load output and cleaning the ulity AC pow-
er. When the 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 replace
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 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

Wiring and Connecng
Inial Connecon
1. The UPS-XBDM-20RHW is a hardwired input and output Bypass Distribuon Module. It must be installed in
conjuncon with all local electrical codes, with work performed by a licensed electrician.
2. All connecons should be completed prior to providing input ulity power to the UPS-XBDM-20RHW.
3. Input and Output wiring to the UPS-XBDM-20RHW should be routed through the terminal box knockout. The
terminal box cover can be removed for ease of conduit connecon and wire roung.
Input and Output Roung
4. Please refer to the drawing below for input and output wiring terminal locaons.
Terminal Block View
Startup Sequence
1. Turn the UPS OFF in accordance with UPS manufacturers’ documentaon. Verify the correct wiring to the
XBDM prior to proceeding to step 2.
2. Unplug the UPS from ulity source. Depending on the model of UPS it may take a few seconds for the UPS
to completely shut down. All indicators on the UPS front panel should shutdown.
3. Disconnect the protected equipment power cord(s) from the UPS.
4. Verify that the BYPASS switch on the XBDM is in the UPS posion.
5. Energize the circuit breaker providing input ulity to the UPS-XBDM-20RHW from a properly sized distribu-
on panel.
The orange bypass available light should illuminate on the Bypass Distribuon Module.
6. Plug the UPS INPUT cord into the 5-20R receptacle labeled FOR UPS INPUT on the rear of the UPS-XBDM-
20RHW.
7. Connect the UPS output receptacle to the UPS-XBDM-20RHW C20 plug labeled UPS OUTPUT using the
appropriate 20A cord supplied with the UPS-XBDM-20RHW.
8. Assure that the distribuon for the loads to be connected to the UPS-XBDM-20RHW is properly connected
to the UPS-XBDM-20RHW.
9. Press the ON BUTTON on the UPS. All indicators on the UPS should operate normally. The red UPS avail-
able light should illuminate on the Bypass Distribuon Module. Power should now be supplied to the
equipment connected to the UPS via the UPS-XBDM-20RHW.
