The input circuit breaker will trip in the event the load exceeds the UPSs power rating.

INSTALLATION

INSTALLATION PLACEMENT

Install the UPS in a temperature controlled environment that is free of conductive contami-

nants. Select a location which will provide good air circulation for the UPS at all times. Avoid

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.

CONNECTING TO AN AC SOURCE

Plug the UPS into a two pole, three wire, grounded receptacle only. Do not use extension

cords or adapter plugs.

COMPUTER INTERFACE CONNECTION (OPTIONAL)

Minuteman Power Management software and interface cables kits can be used with the MBK

520 & MBK 680 units. Use only Minuteman or Minuteman approved interface cables with

these UPSs. 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.

TELEPHONE SURGE PROTECTION CONNECTION (OPTIONAL)

Connect a single line telephone to the protection sockets on the rear of the UPS. This

connection will require another length of telephone cable. The cable coming from the

telephone service is connected to the port marked IN, the OUT port is connected to the

equipment to be protected.

NOTE:

CONNECTING TO THE COMPUTER INTERFACE PORT IS OPTIONAL. THE

UPS WORKS PROPERLY WITHOUT A CONNECTION.

NOTE:

CONNECTING TO THE TELEPHONE SURGE PROTECTION

CONNECTION IS OPTIONAL. THE UPS WORKS PROPERLY WITHOUT A

CONNECTION.

CHECKING THE SITE WIRING FAULT (120 VAC models only)

After plugging in the UPS check the site wiring fault (SWF) LED on the rear of the unit. If the

LED is illuminated the UPS is plugged into an improperly wired AC outlet.

CHARGING THE BATTERY

The MBK Series UPSs 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.

CAUTION!

IF THE UPS INDICATES A SITE WIRING FAULT, HAVE A QUALIFIED

ELECTRICIAN CORRECT THE PROBLEM.

CONNECTING YOUR EQUIPMENT

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.

OPERATION

TURNING THE UNIT ON/OFF

Press and release the switch after one beep to turn the unit on and supply power to the load.

The load are immediately powered while the UPS runs a 5 second self test. Press and

release the switch to turn the unit off. The UPS will continue to charge the batteries whenever

it is plugged in and there is AC present.

On / Off / TestSwitch

SELF TEST

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 batterys capability to provide an acceptable amount of

runtime.

ALARMS

ON BATTERY

When the UPS is operating on the batteries the on-line LED will blink and the audible alarm

will sound every 10 seconds. The alarm will stop once the UPS returns to on-line operation.

UPS FAULT

When the UPS detects a hardware fault the UPS will emit a sustained tone. The fault

condition can be re-set by turning the UPS off and then on (see section 5 for more informa-

tion).

OVERLOAD

When the amount of load attached to the UPS exceeds its power rating the UPS will emit a

sustained tone. This alarm will remain on until the excess load is removed or the UPSs self

protection circuit shuts the UPS down.

REPLACE BATTERY

The UPS automatically tests the batterys condition and will emit a short beep. This tone will

be repeated every hour until the battery passes a self test. It is recommended that the UPS

be allowed to charge overnight before performing a battery test to confirm a replace battery

condition.

LOW BATTERY WARNING

The UPS will emit two consecutive beeps every five seconds when the battery reserve runs

low. This continues until AC returns or the UPS shuts down from battery exhaustion.

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.

COMMUNICATIONS PORT
