 2 Safety Instructions
This section contains important safety instructions that should always be followed during the in-
stallation, use and maintenance of the UPS.

• 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 carry-
ing out the installation, read the instructions and take account of the product’s specific mount-
ing location. Do not open up, dismantle, alter or modify the device except where specifically
required to do so by the instructions. All Legrand products must be opened and repaired ex-
clusively 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.
• If any visible damage is found on the product during the unpacking operation, do not install the
UPS but repack the unit and return it to your reseller or distributor.
• Before operating the UPS or connecting any load equipment, ensure the UPS is connected to a
properly grounded electrical supply.
• The load applied must not exceed the one indicated on the type label of the UPS.
• The ON/OFF button of the UPS does not electrically isolate the internal parts. To isolate the UPS,
unplug it from the mains power socket.
• Do not attempt to open or disassemble the UPS; 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 mains socket outlet that supplies the UPS shall be installed near the UPS and shall be easily
accessible.
• Do not plug non-computer-related items such as medical, life-support and house electric equip-
ments to the UPS output.
• Do not plug laser printers to the UPS output because they have a high start-up current.
• The UPS has its own internal energy source (batteries). If the UPS is switched on when no AC
power is available, there is hazardous voltage at the output sockets.
The batteries inside the UPS are not user-replaceable. Servicing of batteries must be
performed only by electrical hazard authorized personnel.

CAUTION: A battery can present a risk of electrical shock and high short circuit current.
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.

36
 DAKER DK Plus
1 kVA - 3 kVA

The likelihood of such shock can be reduced if such grounds are removed during installa-
tion and maintenance (applicable to equipment and remote battery supplies not having a
grounded supply circuit).

CAUTION: Do not dispose of batteries in a fire. The batteries may explode.

EN
CAUTION: Do not open or mutilate batteries. Released electrolyte is harmful to the skin and
eyes. It may be toxic.

• This UPS has dangerous high 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 to disable the UPS.
• Do not allow any liquid or any foreign object to enter the UPS.
• The UPS 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
between 20% and 80%.
• Do not install the UPS in locations with sparks, smoke and hazardous gas or where there is water
and excessive humidity. Dusty, corrosive, and salty environments can damage the UPS.
• Do not plug the UPS input into its own output.
• Do not attach a power strip or surge suppressor to the UPS.
• Do not cover the cooling vents and keep a clearance of 20 cm beyond the UPS rear panel. Avoid
exposing it to direct sunlight or installing it near heat emitting appliances.
• Unplug the UPS prior to cleaning and do not use liquid or spray detergent.
• Do not place the UPS near equipments that generate strong electromagnetic fields and/or near
equipments that are sensible to electromagnetic fields.

WARNING
All the UPSs are category C2 products according to the EN 62040-2. In a residential en-
vironment, these equipments may cause radio interference, in which case the user may be re-
quired to take additional measures.
