If any problems are encountered with the procedures contained in this manual, please contact the
nearest Service Centre before you proceed.
All UPS installation, maintenance and service work should be performed by qualified service personnel
only.
The KNOWLEDGE and the FULLY compliance of the safety instructions and the warning
contained in this manual are
THE ONLY CONDITION
to avoid any dangerous situations during installation, operation, maintenance work,
and to preserve the maximum reliability of the UPS system.
NOTE !
LP 33 Series / 10 - 20 - 30 kVA is a Class A-UPS Product (according to EN 50091-2).

1.1 IMPORTANT SAFETY RULES
GENERAL
• Move the UPS in an upright position in its original package to the final destination room.
• To lift the cabinets, use a forklift or lifting belts with spreader bars.
• Check for sufficient floor and elevator loading capacity.
• Check carefully the integrity of the UPS equipment.
In case you note some visible damage, do not put the UPS under voltage, but contact the nearest
Service Centre.
• WARNING: RISK OF ELECTRICAL SHOCK.
Apart the front hinged lockable doors, do not remove any covers, there are no user serviceable
parts inside.
• After switching off takes 5 minutes for the DC capacitors to discharge because a lethally high
voltage remains at the terminals of the electrolytic capacitors.
• All maintenance and service work should be performed by qualified service personnel.
• The outlet-bars may be electrically live, even when the UPS is disconnected from the mains.
• Dangerous voltages may be present during battery operation.
• The battery protections must be removed before any maintenance or service work.
• Be aware that the inverter can restart automatically after the utility voltage is restored.
INSTALLATION
• This UPS must be installed and connected only by trained personnel.
• Verify accurately during Commissioning and Maintenance of the UPS, for the following:
Damaged components, squeezed wires and cables, or not correctly inserted plugs.
• After removing the sidewalls of the UPS, make sure that all earth connections when reassembling,
are correctly reattached.
• This UPS is intended for use in a controlled indoor environment free of conductive contaminants
and protected against animals intrusion.
• High earth leakage current: Earth connection essential before connecting to AC input.
• Switching OFF the unit does not isolate the UPS from the mains.
• Do not install the UPS in an excessively humid environment or near water.
• Avoid spilling liquids on or dropping any foreign object into the UPS.
• The unit must be placed in a sufficiently ventilated area; the ambient temperature should not
exceed 35°C (95°F).
• Optimal battery life is obtained if the ambient temperature does not exceed 25°C (77°F).
• It is important that air can move freely around and through the unit.
• Do not block the air vents.
• Avoid locations in direct sunlight or near heat sources.

OPM_LPS_33E_10K_30K_4GB_V030.doc Operating Manual LP 33 Series / 10-20-30 kVA
STORAGE
• Store the UPS in a dry location; storage temperature must be within -25°C to 55°C (-13°F to 131°F).
• If the unit is stored for a period exceeding 3 months, the batteries must be recharged periodically
(time depending on storage temperature).
BATTERY
• The battery-voltage is dangerous for person’s safety.
• When replacing the battery, use the same number, voltage (V) and capacity (Ah).
Do not connect battery strings of different type in parallel.
• Proper disposal or recycling of the battery is required.
Refer to your local codes for disposal requirements.
• Never dispose of battery in a fire: they may explode.
• Do not open or mutilate battery: their contents (electrolyte) may be extremely toxic.
If exposed to electrolyte, wash immediately with plenty of water.
• Avoid charging in a sealed container.
• Never short-circuit the batteries.
• When working with batteries, remove watches, rings or other metal objects, and only use insulated
tools.
WARNING !
The UPS contains hazardous voltages.
Observe carefully the safety instructions to prevent risk of
electrical shock.

Safety instructions when working with battery
EXTERNAL BATTERY MUST BE INSTALLED AND CONNECTED TO THE UPS BY
QUALIFIED SERVICE PERSONNEL.
INSTALLATION PERSONNEL MUST READ THIS ENTIRE SECTION BEFORE HANDLING
THE UPS AND BATTERY.
DANGER!
Full voltage and current are always present at the battery terminals.
The battery used in this system can provide dangerous voltages, extremely high currents and
a risk of electric shock.
If the terminals are shorted together or to ground they may cause severe injury.
You must be extremely careful to avoid electric shock and burns caused by contacting battery
terminals or shorting terminals during battery installation.
Do not touch uninsulated battery terminals.
A qualified service person, who is familiar with battery systems and required precautions,
must install and service the battery.
The installation must conform to national and local codes.
Keep unauthorised personnel away from the battery.
The qualified service person must take these precautions:
1 Wear protective clothing, such as rubber gloves and boots and protective eye wear
Batteries contain caustic acids and toxic materials and can rupture or leak if mistreated.
Remove rings and metal wristwatches or other metal objects and jewelry.
Do not carry metal objects in your pockets where the objects can fall into the battery
cabinet.
2 Tools must have insulated handles and must be insulated so that they will not short battery
terminals.
Do not allow a tool to short between individual or separate battery terminals or to the
cabinet or rack.
Do not lay tools or metal parts on top of the battery, and do not lay them where they could
fall onto the battery or into the cabinet.
3 Install the battery as shown on the drawing provided with the battery.
When connecting cables, never allow a cable to short across a battery’s terminals, the
string of battery, or to the cabinet or rack.
4 Align the cables on the battery terminals so that the cable lug will not contact any part of
the cabinet or rack, even if the battery is moved.
Keep the cable away from any sharp metal edges.
5 Install the battery cables in such a way that the UPS or battery cabinet doors cannot pinch
them.
6 Do not connect the battery terminal to Ground.
If any battery terminal is inadvertently grounded, remove the source of the ground.
Contacting any part of a grounded battery can cause a risk of electric shock.
7 To reduce the risk of fire or electric shock, install the battery in a temperature and humidity
controlled indoor area, free of contaminants.
8 Battery system chassis ground (earth) must be connected to the UPS chassis ground
(earth).
If you use conduits, this ground conductor must be routed in the same conduit as the
battery conductors.
9 Where conductors may be exposed to physical damage, protect the conductors in
accordance with all applicable codes.
10 If you are replacing the battery or repairing battery connections, shut OFF the UPS and
remove the battery fuses.
