Installation Notes
•
Place the UPS in a clean, stable environment, avoiding vibration, dust, humidity, flammable gas
and liquid, corrosive objects, etc. Check the operating temperature of the room where the UPS
is being installed to assure it is within range of UPS specification.
•
Batteries should be installed in an environment where the temperature is within the required
specifications of the product. Temperature is a major factor in determining battery life and
capacity. Normal battery installation requires the temperature be maintained from 15
°
C to
25
°
C. Keep batteries away from heat sources and main air ventilation areas.
WARNING!
Typical battery performance data is quoted for an operating temperature between 20
°
C and
25
°
C. Operating above this range will reduce the battery life while operation below this range
will reduce the battery capacity.
•
If the equipment is not to be installed immediately, it must be stored in a room so as to protect
it against excessive heat and humidity sources.
CAUTION!
An unused battery must be recharged every 6 months. Temporarily connecting the UPS to a
suitable AC source and activating the UPS for the time required to recharge the batteries is required.
•
To monitor the UPS with the software, simply connect the RS232 cable to the UPS and to a
computer.
External Protective Devices
For safety reasons, it is necessary to install an external circuit breaker at the input AC utility and to the
battery.
External Battery
The UPS and its associated batteries are protected against the effect of over-current through a
DC compatible thermo-magnetic circuit breaker located close to the battery.
UPS Output
Any external distribution board used for load distribution shall be fitted with protective devices
so as to avoid the risk of UPS overload.
Over-Current Protection
A protection device shall be installed at the distribution panel of the incoming utility power, and
should identify the power cables current capacity as well as the overload capacity of the system.
