1 Introduction

The Keor LP is an Uninterruptible Power Supply (UPS) designed for home, commercial and

industrial application. This manual contains information for users of the Keor LP 1,2,3 kVA models.

You are advised to read carefully this handbook and the safety instruction sheet included in

the packaging before installing your uninterruptible power supply, meticulously following

the instructions given herein. In case of problems with the UPS, please read this manual before

contacting the technical support;

Please download the latest version of the manual from the website: www.ups.legrand.com

• The UPS has been designed to supply data processing equipment; The load applied must not

exceed the one indicated on the rear label of your UPS.

Ensure that the input voltage of the UPS matches the utility supply voltage. Use a certified input

power cable with the correct plugs and sockets for the system voltage.

• The ON/OFF button of your UPS does not electrically isolate the internal parts. To isolate your

UPS unplug it from the mains power socket.

• Do not open the UPS container since there may be parts inside with dangerously high voltage

even when the mains plug is disconnected; there are no parts inside that the user can repair.

• The front control panel is provided for manual operations; Do not press on the panel with sharp

or pointed objects.

• The UPS Keor LP has been designed to work in closed, clean rooms where there are no

inflammable liquids or corrosive substances and where it is not too damp.

• Do not place near equipments that generate strong electro-magnetic fields and/or near

equipments that are sensible to electro-magnetic fields. (engines, floppy disks, speakers,

adapters, monitors, video, etc...)

• Do not pour any liquid on the UPS or inside the UPS.

• Do not place the UPS in humid environment or near liquid, such as water, chemical solution…

• Do not expose the UPS to the direct sunlight or any heat sources.

Ensure that the installation site is free from excessive dust and the ambient temperature and

humidity are within the specified limits.

Do not place the UPS in a dusty or corrosive environment or near any flammable objects.

This UPS is not designed for outdoor use.

• Keep the ventilation slits clean to dissipate the heat of the UPS.

To prevent overheating of the UPS keep all ventilation openings free from obstruction, and do not place

anything on top of the UPS. Keep the UPS rear panel 20 cm away from the wall or other obstructions

• Use grounded power cable to connect the UPS to the mains supply.

This UPS is equipped with an EMI filter. To prevent potential leakage current hazards ensure that

the AC mains supply is securely grounded.

• Install the UPS close to the mains socket that supply it.The socket must be easily accessible.

• Do not plug laser printers into the UPS because of their high start-up current.

• Do not plug house electric equipments, such as hair dryer, air conditioner, and refrigerator into

the UPS outlets.

- Always switch off the UPS and disconnect the batteries when relocating the UPS. Be aware that,

even when disconnected, charged batteries present a possible electric shock hazard.

- The UPS should be recharged every 2-3 months if unused. When installed and being used the

batteries will be automatically recharged

Storage

If the UPS is unused for an extended period of time it must be stored in a moderate climate.

The batteries should be charged for 12 hours every three months by connecting the UPS to the

utility supply and switching on the input breaker located on the UPS rear panel. Repeat this

procedure every two months if the storage ambient temperature is above 25°C.

1 = REPO+

2 = Ground

To enable the EPO function short pins 1 and 2.

Proceed to the installation as follows :

Please read the condition of use contained in this manual before installing the UPS.

Start

Normal AC mode

1. Before commencing ensure that the grounding is connected properly.

2. Ensure that the utility voltage matches the input voltage window of the UPS.

3. Connect the UPS main power cord into the utility AC power source receptacle, that has to be

placed near the UPS and easily accessible.

4. Switch on the AC power source. All of the LEDs on the front panel display will flash once after

five seconds. At the same time, the fan at the front of the UPS will start operating.

5. Press and hold the ON button

for approximately one second to start the UPS. The buzzer

will beep and the LED indicators

and

will shine after 1-5 seconds.The start-up

procedure is now completed, and the UPS outlets are ready to supply power to the load.

6. It is advisable to perform a battery mode test before connecting the loads to the UPS to ensure

that the batteries are working properly. To do this, switch off the AC power source when the

UPS is on. The LED on the front panel display will turn off, the LED will shine, and the buzzer

will pulsate, indicating that the UPS is in Battery Mode. Connect a non-critical load to the UPS

outlets to confirm that the batteries are supplying power. Repeat the test by switching on and

off the AC power source to ensure that the UPS is functioning properly.

Self Testing in AC Mode

After the UPS has been successfully started in AC mode, press and hold the Self-Test button

for five seconds until the buzzer beeps. The

LED will shine to indicate that the self-test is in

progress. When the self-test is completed the UPS will return to AC mode. If there were no faults or

abnormal conditions then the

and

LEDs will turn off.

Note: the main function of self testing is to run a discharge test on the batteries.

Battery mode (Cold Start)

This UPS can be switched on without the presence of an AC power source.

Press and hold the ON button

until the buzzer beeps. Release and then within the next

10 seconds press and hold the same button a second time. The UPS will perform its start-up

procedure. The LEDs

and

will shine after 1-5 seconds, and the buzzer will

pulsate to indicate successful power-on.

Note: Ensure that the UPS batteries are pre-charged for at least four hours by simply connecting

the AC power cord to the utility receptacle.

Shutdown

AC mode

Press and hold the OFF button

for five seconds until the buzzer beeps. The UPS will cut the

power supply to the outlets. The ventilating fans will continue to operate. Switch off the AC power

source. The ventilating fans will stop. The UPS is now completely shut down.

DC mode

Press and hold the OFF button

for five seconds until the buzzer beeps. The UPS will cut the

power supply to the outlets. The LEDs will turn off, and the ventilating fans will stop after ten

seconds and the ±BUS discharge is below 42 V. The UPS is now completely shut down.
