PM SERIES
Typical battery performance data are quoted for an operating temperature between
20°C and 25°C. Operating it above this range will reduce the battery life while
operation below this range will reduce the battery capacity.
• Should the equipment not be installed immediately it must be stored in a room so as to protect
it against excessive humidity and or heat sources.
CAUTION!
An unused battery must be recharged every 6months temporarily connecting the
UPS to a suitable AC supply mains and activating it for the time required for
recharging the batteries.
• The highest altitude that UPS may work normally with full load is 1500 meters. The load
capacity should be reduced when this UPS is installed in place whose altitude is higher than
1500 meters, shown as the following table:
(Load coefficient equals max load in high altitude place divided by nominal power of the UPS)
Altitude(m)
Load coefficient
• The UPS cooling is depending on fan, so it should be kept in good air ventilation area. There
are many ventilation holes on the front and rear, so they should not be blocked by any exotic
obstacles.
3.6 External Protective Devices
For safety reasons, it is necessary to install, external circuit breaker at the input A.C. supply and
the battery. This chapter provides guidelines for qualified installers that must have the
knowledge of local wiring practices for the equipment to be installed.
• External Battery
The UPS and its associated batteries are protected against the effect of over-current through a
DC compatible thermo-magnetic circuit-breaker (or a set of fuses) located close to the
battery.
• UPS Output
Any external distribution board used for load distribution shall be fitted with protective
devices that may avoid the risk of UPS overloaded.
• Over-current
Protection device shall be installed at the distribution panel of the incoming main supply. It
may identify the power cables current capacity as well as the overload capacity of the system.
