2. Regulatory and safety requirements
2.5 Signs on the equipment
Displayed on the EBC are explanatory plates that can vary depending on the country the equipment is intended for, and
constructional standards applied.
Make sure the instructions are adhered to. Removing these plates and working in a way that differs from what written
there, is strictly prohibited.
The plates must always be clearly read, and they must be cleaned periodically.
If a plate deteriorates and/or it is no longer legible, even partially, the Manufacturer must be contacted for another one.
CAUTION
The plates must not be removed or covered. Signs in different languages are provided along with the cabinet in order to
replace the default ones in English. No other plates may be affixed to the equipment without the Manufacturer’s prior
written authorisation
WARNING
Potential risks can be drastically reduced by wearing the Personal Protective Equipment listed in this chapter, which are
indispensable. Always operate with due care around dangerous areas marked by the appropriate warning notices on the
equipment.
2.6 General warnings
DANGER
The battery cabinet works with dangerous voltages. SKILLED TECHNICIANS shall perform the installation and
ordinary maintenance operations. No part of the equipment can be repaired by the operator.
Extraordinary maintenance operations must be carried out by LEGRAND Technical Support Service personnel.
DANGER
Before beginning any installation and/or maintenance operation, make sure that all the DC and AC power sources are
disconnected.
The UPS and the battery cabinet must be installed with an earth connection to avoid high leakage currents. First connect
the earthing cable.
Check during each installation and/or maintenance operation the continuity of the earthing system.
WARNING
A battery can present a risk of electrical shock and high short circuit current. The following precautions should be ob-
served 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 sup-
plies not having a grounded supply circuit).
g) never leave live cable terminals without an insulated protection.
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
Do not open the battery fuse holders while the UPS is powering the loads in battery mode.
