Regulatory and safety requirements

This section contains important safety and operating instructions that should always be followed during the installation, use and maintenance of the battery cabinet.

DANGER
The Keor SPE UPS and battery cabinet work with dangerous voltages. Only skilled technicians qualified and authorized by LEGRAND must perform ordinary maintenance operations. No part of the battery cabinet can be repaired by the user. Extraordinary maintenance operations must be carried out by LEGRAND Technical Support Service personnel.

This product should be installed in compliance with installation rules, preferably by a qualified electrician. Incorrect installation and use can lead to risk of electric shock or fire. Before carrying out the installation, read the instructions and take account of the product’s specific mounting location. Do not open, dismantle, alter or modify the device except where specifically required to do so by the instructions. All Legrand products must be opened and repaired exclusively by personnel trained and approved by Legrand. Any unauthorised opening or repair completely cancels all liabilities and the rights to replacement and guarantees. Use only Legrand brand accessories.
Ensure that the mains supply voltage and frequency match those of the UPS (see the product label and the technical specifications).
If any visible damage is found on the product during the unpacking operation, do not install the equipment but repack the unit and return it to your reseller or distributor.
Before operating the UPS with its battery cabinet, ensure the UPS and the battery cabinet are connected to a properly grounded mains socket.
Do not attempt to open or disassemble the battery cabinet; there are no user replaceable parts.
Opening the case will void the warranty and introduces the risk of electric shock even when the mains plug is disconnected.
The battery cabinet has dangerous voltages on its input and output connections. Contact with these voltages may be life threatening.
In case of emergency, immediately turn off the equipment and disconnect the power cord from the AC power supply.
Do not allow any liquid or any foreign object to enter the battery cabinet.
The battery cabinet is intended for indoor installation in a ventilated, controlled indoor environment with a range of temperature between 0°C (+32°F) and +40°C (+104°F) and non-condensing humidity <95%.
Do not install the equipment in locations with sparks, smoke, and hazardous gas or where there is water and excessive humidity. Dusty, corrosive, and salty environments can damage the equipment.
Do not plug the battery cabinet input into its own output.
Keep a clearance of 20 cm beyond the rear panel. Avoid exposing it to direct sunlight or installing it near heat emitting appliances.
Unplug the battery cabinet prior to cleaning and do not use liquid or spray detergent.
Do not place the equipment near equipment that generate strong electromagnetic fields and/or near equipment that are sensible to electromagnetic fields.
The battery cabinet should be recharged every 2-3 months if unused. To do so, connect the power cable to a suitable grounded mains socket.
To safeguard the batteries as well as possible it is necessary to bear in mind that their average lifetime is strongly influenced by the operating room temperature. Position the UPS in an environment with a temperature range between +20°C (+68°F) and +25°C (+77°F) to guarantee the optimum life of the batteries.

DANGER
Make sure that the UPS is turned off and the both the UPS and the battery cabinet are completely disconnected from the AC power before carrying out and maintenance, battery replacement or repair.

CAUTION
The batteries inside the battery cabinet are not user-replaceable. Servicing of batteries must be performed only by electrical hazard authorized personnel.
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.

CAUTION
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.

Installation

Package Inspection

During transportation, some unpredictable situations might occur. It is recommended that you inspect the UPS’s exterior packaging. If you notice any damage, please immediately contact the dealer from whom you purchased the unit.
Also check the rating label on the UPS and make sure the device No. and capacity match what you ordered. Examine if any parts are loose or damaged.

The UPS package contains the following items. Please check if any items are missing.

No.	ITEM	QTY
1	Battery cabinet
2	Tower stands
3	Bracket ears
4	Quickstart
5	Handles
6	AC power cord
7	Power cord
8	Pan head screws M5
9	Pan head screws M4

Positioning constraints

The UPS can be installed vertically (tower-mounting) or horizontally (rack- mounting) according to the user’s desired arrangement. Do not mount the UPS with its front or rear panel facing down at any angle Keep at least 100 mm of free space in front and at the rear of the UPS for proper ventilation. Always keep the UPS upright and handle it with care.
Do not stack the units.
Do not place any objects on the UPS, the external battery pack (optional) or any other accessory associated with the UPS.
Install the UPS on a level and even surface.
For tower-mounting installation, ensure that your chosen location’s floor can bear the weight of the UPS.
For rack-mounting installation, make sure your chosen cabinet can support the weight of the UPS and the rails that may be mounted in an associated rack. You also need to take your chosen location’s floor weight loading into consideration.
For rack-mounting installation, do not let your rack become ‘top heavy’. Install the heaviest equipment near the bottom of the rack.
