1 IMPORTANT SAFETY INSTRUCTIONS
SAVE THESE INSTRUCTIONS
This manual contains important instructions for models SG Series 50 and 80 kVA 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 the nearest Service Center
immediately.
- WARNING! RISK OF ELECTRICAL SHOCK: Do not remove covers; there are no user serviceable
parts inside.
- All maintenance and service work should be performed by qualified service personnel.
The UPS contains its own energy source (battery).
- The field-wiring terminals 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.
- HIGH GROUND LEAKAGE CURRENT: Ground 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).
- 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 number, voltage (V) and capacity (Ah).
-
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 battery.
When working with battery, remove watches, rings or other metal objects, and only use
insulated tools.
