set out in the Radio Interference of the Canadian Department of Communications. These limits
are designed to provide reasonable protection against such interference in a residential installa-
tion. This equipment generates and uses radio frequency and if not installed and used properly,
that is, in strict accordance with the manufacturer's instructions, this equipment may cause
interference to radio and television reception. If this equipment does cause interference to radio
or television reception, which can be determined by turning the equipment off and on, the user
is encouraged to try to correct the interference by one or more of the following measures:
NOTICE:
This equipment has been tested and found to comply with the limits
for a Class B computing device in accordance with the specifications in Subpart J
of Part 15 of FCC Rules and the Class B limits for radio noise emissions from digital
apparatus
n
Re-orient the receiving antenna
n
Relocate the computer with respect to the receiver
n
Move the computer away from the receiver
n
Plug the computer into a different outlet so that the computer and receiver are on
different branch circuits.

nspection
After removing your Minuteman UPS from its carton, it should be inspected for damage that
may have occurred in shipping. Immediately notify the carrier and place of purchase if any
damage is found. Warranty claims for damage caused by the carrier will not be honored.
The packing materials that your UPS was shipped in are carefully designed to minimize any
shipping damage. In the unlikely case that the UPS needs to be returned to Minuteman,
please use the original packing material. Since Minuteman is not responsible for shipping
damage incurred when the system is returned, the original packing material is inexpensive
insurance.
PLEASE SAVE THE PACKING MATERIALS!
WARNING:
RISK OF ELECTRICAL SHOCK. HAZARDOUS LIVE PARTS
INSIDE THIS POWER SUPPLY ARE ENERGIZED FROM THE BATTERY EVEN
WHEN THE AC INPUT POWER IS DISCONNECTED.
TO DE-ENERGIZE THE OUTPUTS OF THE UPS:
1.
IF THE UPS IS ON PRESS THE ON/OFF BUTTON FOR 1 SECOND
2.
DISCONNECT THE UPS FROM THE AC POWER OUTLET
3.
TO DEENERGIZE THE UPS COMPLETELY,
DISCONNECT THE
BATTERY.
(SEE SECTION 6 FOR INSTRUCTIONS)
CAUTION!
TO REDUCE THE RISK OF ELECTRICAL SHOCK IN
CONDITIONS WHERE LOAD EQUIPMENT GROUNDING CANNOT BE VERI-
FIED, DISCONNECT THE UPS FROM THE AC POWER OUTLET BEFORE
INSTALLING A COMPUTER INTERFACE CABLE. RECONNECT THE POWER
CORD ONLY AFTER ALL SIGNALING CONNECTIONS ARE MADE.
CAUTION!
CONNECT THE UPS TO A TWO POLE, THREE WIRE
GROUNDING AC POWER OUTLET. THE RECEPTACLE MUST BE CONNECTED
TO APPROPRIATE BRANCH PROTECTION (CIRCUIT BREAKER OR FUSE).
CONNECTION TO ANY OTHER TYPE OF RECEPTACLE MAY RESULT IN A
SHOCK HAZARD AND VIOLATE LOCAL ELECTRICAL CODES
Para Systems Life Support Policy

locations near heating devices, water or excessive humidity, or where the UPS is exposed to
direct sunlight. Route power cords so they cannot be walked on or damaged.

these UPSs. Connect the interface cable to the 9 pin computer interface port on the rear of
the UPS. Secure the connector to the UPS via the screws on the connector housing. Connect
the other end of the cable to the device that will be monitoring/controlling the UPS.

The MBK Series UPSs will charge the internal batteries whenever the unit is connected to an
AC source. It is recommended that the UPS batteries be charged for a minimum of 4 hours
before use. The UPS may be used immediately however the on battery run time may be
less than normally expected.

IF THE UPS INDICATES A SITE WIRING FAULT, HAVE A QUALIFIED
ELECTRICIAN CORRECT THE PROBLEM.

Plug the equipment into the receptacles on the rear of the unit. Insure
that you do not exceed the maximum output rating of the UPS (refer to
UPS back panel or electrical specifications in this manual).
CAUTION!
DO NOT CONNECT A LASER PRINTER TO THE BATTERY BACKUP
RECEPTACLES ON THE UPS UNLESS THE UPS IS RATED 2000VA OR
GREATER. A LASER PRINTER DRAWS SIGNIFICANTLY MORE POWER
WHEN PRINTING THAN AT IDLE, AND MAY OVERLOAD THE UPS.

On / Off / Test Switch
The self test feature is useful to verify the correct operation of the UPS and the condition of
the battery. With the UPS plugged into normal AC press and hold the ON/OFF/TEST
SWITCH for 4 seconds (four beeps) then release the switch. The UPS will perform a five
second self test.
Note: The UPS will automatically perform a self test on startup and every two
weeks.
During the self test the UPS will switch to battery power and the on-line LED will blink and the
audible alarm will sound as well. The length of the test that automatically is performed every
two weeks is longer than the start-up or user invoked test. This test will run for approximately
fifteen seconds to measure the batterys capability to provide an acceptable amount of
runtime.

USER NOTES
Rear Panel Switch Functions
During normal AC operation the rear panel
switch may be used to change the low voltage
transfer level. This voltage is the voltage at which
the unit switches from normal operation to battery
mode operation. The transfer point is changed by
pressing and holding the switch until the switch
level desired is achieved. The factory default level
is 105 VAC (international version is 200VAC).
1) Press and hold the switch until the unit sounds
the audible alarm one time to change the level
to 98 VAC (185vac).
2) Press and hold the switch until the unit sounds the audible alarm twice sequentially to
change the level to 91 VAC (170AC).
3) Press and hold the switch until the unit sounds the audible alarm three times sequentially
to reset to default setting.
While operating in the battery backup mode, the rear panel switch may be used to silence the
audible alarm. Press and hold the switch until the unit sounds the audible alarm once to
silence the audible alarm. The audible will reset and provide an alarm if the unit batteries are
nearing depletion. This is referred to as the low battery warning alarm. When utility power
returns and the unit switches to normal AC mode, the audible alarm will reset automatically to
provide a warning at the next power failure.

The communications port is a standard DB9 female with both RS232 and simulated contact
closure capability. The Pro series units will poll the port and activate the port for RS232 or
contact closure in accordance with the type of cable it finds connected to the port. To change
the port configuration requires the unit be turned off and restarted with the desired cable
connected. The pinout for the port is depicted per the chart below.
