1 IMPORTANT SAFETY INSTRUCTIONS
SAVE THESE INSTRUCTIONS
This manual contains important instructions for models SG Series 750 & SG Series 750 T12 that should
be followed during installation and maintenance of the UPS and battery.
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 the integrity of the UPS equipment carefully.
If you notice visible damage, do not install or start the UPS.
Contact your Service Center immediately.
- WARNING! RISK OF ELECTRICAL SHOCK:
Do not remove 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 UPS contains its own energy source (battery).
- The field-wiring outlets may be electrically live, even when the UPS is disconnected from the utility.
- Dangerous voltages may be present during battery operation.
- The battery must be disconnected during maintenance or service work.
- This UPS contains potentially hazardous voltages.
- 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.
- WARNING! HIGH EARTH LEAKAGE CURRENT:
Earth connection is essential before connecting to AC input!
- Switching OFF the unit does not isolate the UPS from the utility.
- 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 104°F (40°C).
- Optimal battery life is obtained if the ambient temperature does not exceed 77°F (25°C).
- 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.
STORAGE
- Store the UPS in a dry location; storage temperature must be within -13°F (-25°C) to 131°F (+55°C).
- The optimal temperature for Battery storage is 68°F (20°C) to 77°F (25°C) and shall never exceed the range
-4°F (-20°C) to 104°F (40°C).
- If the unit is stored for a period exceeding 3 months, the battery 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 cells number, voltage (V), capacity (Ah).
All the battery used, shall be of the same manufacturer and date of production.
- 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.
- In case of air shipment, the cables +/- going to the battery fuses/terminals shall be disconnected and isolated.

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 un-insulated 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 unauthorized 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 jewellery.
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.
