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 carrying
out the installation, read the instructions and take account of the product’s specific mounting
location. Do not open up, dismantle, alter or modify the device except where specifically requi-
red 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.
• 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
equipments 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.
