DANGER
Before carrying out any operation, it is necessary to read the entire manual carefully, especially this chapter.
Consult it repeatedly during installation and maintenance by a skilled technician.
2.1 General notes
The equipment has been made for the applications given in the manual. It may not be used for purposes other than those
for which it has been designed, or differently from those specified in this manual.
The various operations must be carried out according to the criteria and the chronology described in this manual.
2.2 Definition of “Skilled Technician”
The figure that will carry out the installation is called “Skilled Technician”.
This definition refers to people who have specific technical qualification which enables them to operate according to
safety standards in relation to the dangers linked to the presence of electric current.
They are aware of the method of installing, assembling, repairing and using the equipment safely.

and uses the personal protective equipment required by national safety standards for all the operations indicated in this
manual (see the examples listed in paragraph 2.3).
2.3 Personal Protective Equipment
DANGER
The installation of batteries in a UPS poses a considerable risk of electric shocks and a high short circuit current. During
installation, use and maintenance operations, the equipment mentioned in this section must be used.
People responsible for operating this equipment and/or passing close to it must not wear garments with flowing sleeves,
nor may laces, belts, bracelets or other metal pieces that might cause a danger.
The following list sum up the minimum Personal Protective Equipment to wear always. Additional requirements may be
needed according to national safety standards.

2.4 General warnings
WARNING
A battery can present a risk of electrical shock and burns by high short-circuit circuit current. Failed batteries can reach
temperatures that exceed the burn thresholds for touchable surfaces. The following precautions should be observed
when working on batteries:
a) remove watches, rings or other metal objects.
b) use tools with insulated handles.
c) wear rubber gloves and boots.
d) do not lay tools or metal parts on top of batteries.
e) disconnect the charging source prior to connecting or disconnecting battery terminals.
f) determine if battery is inadvertently grounded. If inadvertently grounded, remove source from ground.
Contact with any part of a grounded battery can result in electrical shock. The likelihood of such shock can be reduced
if such grounds are removed during installation and maintenance (applicable to equipment and remote battery
supplies not having a grounded supply circuit).
g) never leave live cable terminals without an insulated protection.
h) When replacing batteries, replace with the same type and number of batteries or battery packs. There is the risk of
explosion if batteries are replaced by an incorrect type.
Do not dispose of batteries in a fire. The batteries may explode.
Do not open or mutilate batteries. Released electrolyte is harmful to the skin and eyes. It may be toxic. The batteries
installed inside the cabinet must be disposed of correctly. For the disposal requirements refer to local laws and relevant
standards.
CAUTION
To prevent damage or safety hazard, keep the batteries and the UPS cabinet away from flames and any other device that
may cause sparks.
INDICATION
If any visible damage is found on the product during the unpacking operation, do not install the batteries but repack the
units and return them to your reseller or distributor.
INDICATION
Batteries tend to discharge if they are stored and not connected to the UPS. They should be recharged every 2-3 months
if unused. During normal operation, the batteries will be kept charged.
INDICATION
Operating temperatures above the recommended range will result in decreased battery life and performance and will
reduce or void the battery warranty.

3. Installation
DANGER
All installation operations must be carried out exclusively by a SKILLED TECHNICIAN (paragraph 2.2).
WARNING
The installation procedure below explains how to install the battery drawers and battery blocks if the UPS Keor MOD is
completely turned OFF and disconnected from all sources of supply, including all battery drawers and external battery
cabinets.
In case of replacements of battery drawers with the UPS turned ON, follow strictly the instructions outlined in the UPS
installation manual.
The cabinet for the Keor MOD 125 allows to have from two to ten internal battery drawers. Each battery string is made up
of two drawers therefore it is necessary to install them two by two.
The battery drawers have a specific order in the cabinet that must be kept especially if the UPS has to work in a configuration
with separate batteries (not in common).

Starting from the top of the cabinet, unscrew the four screws that fix the slot cover where the battery drawers must be
installed and save them.
Insert the empty battery drawers in the free slots and push them till you hear a ‘click’.
The battery blocks must be added to the drawers only when these are inserted in the cabinet.

10
In case of empty battery blocks, start inserting the handle in the block.
Insert the batteries in the block and connect them in series using the cables provided and respecting the polarity (connect
a positive terminal of one battery to a negative terminal of another battery).
3. Installation

Keep the batteries firm to the block by fixing a metal bar with the four screws provided.

12
Insert the terminal covers on the four central batteries of the block but not on those at the extremes.
Prepare the remaining three battery blocks in the same way.
In case of battery blocks already filled, remove the terminal covers of the batteries at the extremes.
Add two battery blocks on a drawer and connect in series the two blocks using the cable provided and respecting the
polarity (connect a positive terminal to a negative terminal).

Once the connection is done, insert the terminal covers on the two batteries and push the blocks at the bottom of the
drawer.
Add other two battery blocks on the drawer.

14
Connect in series the two new blocks to the ones already in the drawer using the cable provided and respecting the
polarity (connect a positive terminal to a negative terminal).
Connect the free terminals of the two batteries located close to the handle of the drawer to the cables that go to the back
of the drawer. Check the correct polarity of the whole cabling.

DANGER
All storage and dismantling operations must be carried out only by a SKILLED TECHNICIAN (paragraph 2.2).
The instructions in this chapter are to be considered indicative: in every country there are different regulations
regarding the disposal of electronic or hazardous waste such as batteries. It is necessary to strictly adhere to the
standards in force in the country where the equipment is used.
Do not throw any component of the equipment in the ordinary rubbish.
4.1 Warehousing
Batteries must be stored in an environment with a room temperature between 0°C (+32°F) and +50°C (+122°F) and
humidity less than 90% (not condensing).
The batteries installed inside the battery packs are lead-acid sealed and do not require maintenance (VRLA). The batteries
should be charged for 12 hours every 3 months by connecting the battery drawers to the UPS. Repeat this procedure
every two months if the storage ambient temperature is above +25°C (+77°F).
CAUTION
Batteries must never be stored if partially or totally discharged.
LEGRAND is not liable for any damage or bad functioning caused to the UPS by wrong warehousing of the batteries.
4.2 Dismantling
Batteries must be disposed of in a site intended for the recovery of toxic waste. Disposal in the traditional rubbish is not
allowed.
Apply to competent agencies in your country for the proper procedure.
Pb
WARNING
A battery may constitute a risk of electric shock and high short-circuit current.
When working on batteries, the prescriptions indicated in chapter 2 must be adhered to.
It is important to dismantle the various parts the battery cabinet consists of. For these operations, Personal Protective
Equipment must be worn.
Sub-divide the components separating the metal from the plastic, from the copper and so on according to the type of
selective waste disposal in the country where the equipment is dismantled.
If the dismantled components must be stored before being properly disposed, be careful to keep them in a safe place
protected from atmospheric agents to avoid soil and groundwater contamination.
For the disposal of electronic waste, it is necessary to refer to the industry standards.
