4.2 DELIVERY
When delivered, check carefully the package integrity and the physical conditions of the UPS
equipment.
In case of any damage sustained during transport, immediately inform the carrier and contact your
local Service Center.
A detailed report of the damage is necessary for any insurance claim.
NOTE !
A damaged UPS must never be installed or connected to utility or battery!
4.3 STORAGE
The equipment is carefully packed for transport and storage
so that it is in a perfect condition when eventually installed.
Never leave a UPS outside the building and do not store the
UPS one on top of the other.
It is recommended to store the UPS in its original package in a
dry, dust free room and far away from chemical
substances, with temperature not exceeding -13°F to 131°F
(-25°C to 55°C).
4.3.1 Storage of the UPS
Some important functions of the UPS, such as the customized functions, are defined by parameters
stored in a RAM memory.
The RAM is supplied by a small backup battery located on the Control Unit board.
If the storage time of the UPS exceeds 1 year, these functions should be verified by an authorized
Service Center before putting the UPS into operation.
NOTE !
In case of storage of the UPS pay attention to:
4.3.2 Storage of the battery
In case of extended storage, when the delivery includes maintenance free batteries, keep in mind that
they are subject to auto-discharging process
To avoid permanent damages to the battery, you must observe the following instructions:
The storage time without charging the battery depends on the ambient temperature of the storage area.
The optimal ambient temperature for the batteries is 68°F (20°C).
For storage temperature higher than 68°F (20°C), the storage time will decrease.
Each additional 18°F (10°C) over the nominal temperature of 68°F (20°C) will decrease the storage
time, without freshening charge, by half.
In case of a maintenance free battery, the storage time without charging the battery is
approximately:
6 months with storage temperature 68°F (20°C)
3 months with storage temperature 86°F (30°C)
2 months with storage temperature 95°F (35°C)
NOTE !
In case of battery storage pay attention to:

4.4 PLACE OF INSTALLATION
The UPS should be installed in a restricted area where only qualified personnel should be admitted.
The place of installation should be clean, dust-free, and provided with proper ventilation or air-
conditioning.
Verify for sufficient floor load capacity (see Section 4.1.1).
We strongly advice that the ambient temperature should not exceed 68° - 77°F / 20° - 25°C (max. 104°F
/ 40°C). See Section 4.5.
Positioning of the UPS LP33 Series 20 & 30
Fig. 4.4-1 Positioning LP33 Series 20 & 30
The rear panel of the UPS may be mounted flush to a
wall or other structure.
Clearance around the front of the unit should be
sufficient to enable free passage of personnel with the
doors fully open, and to allow sufficient airflow to the
door vents.
To guarantee proper cooling air exhaust, the
recommended minimum clearance between ceiling
and top of the UPS is 16” (400mm).
Battery cabinets must be placed beside the left side of
the UPS cabinet.
A single-phase power outlet (208Vac) should be
provided near the UPS for connection of power tools,
test equipment or connectivity devices.
This outlet must be grounded.
The LP33 Series 20 & 30 UPS can radiate radio frequency energy.
Although some RFI (Radio Frequency Interference) filtering is inherent to the UPS there is no guarantee that
the UPS will not influence sensitive devices such as cameras and monitors that are positioned close by.
If interference is expected, the UPS should be moved away from the sensitive equipment.
NOTE !
Operating temperature is very important for valve regulated battery (maintenance
free).
Operation at temperatures higher than 68°F (20°C) will reduce life expectancy.
Follow the recommendations of the battery supplier and other local standards.
The installation and cabling of the battery must be done by qualified people.

4.5 VENTILATION AND COOLING
The heat produced by the UPS is transferred to the environment by its internal fan(s).
Fig. 4.5-1 Airflow through the LP33 Series 20 & 30
Airflow through the UPS
It is important that the cooling air can freely flow
through the air inlets and outlets of the UPS.
NOTE !
Insufficient distances on both sides of the
UPS could increase the temperature inside
the UPS.
Do not put any object on the top of the
cabinet: it might obstruct the air flow.
Heat evacuation from UPS
room
The heat must be evacuated
from the environment with a
proper cooling / ventilation
system provided by the user.
