Storage
4.3.1
Storage of the PDU for Later Commissioning
The equipment is carefully packed for transport and storage so that it is in a
perfect condition when eventually installed.
Never leave a PDU outside the building and do not store the PDU one on top of the
other.
It is advisable to store the PDU in its original package in a
dry, dust-free room, away from chemical substances,
and with a temperature range not exceeding
-13°F
(-25°C) to
131°F
(55°C).
Care must be taken to prevent foreign objects to fall into PDU openings (e.g. debris due to construction works or
fasteners). Do not perform construction work over the PDU cabinet.
Some important functions of the PDU, such as the customized functions, are defined by parameters stored in a
RAM memory
.
A small backup Battery located on the Control Unit board supplies the RAM. If the storage time of the PDU
exceeds
1 year
, these functions
should be verified
by an authorized Service Center before putting the PDU into
operation.

environments. The PDU is not intended for use in the presence of explosive gases.
It is important to have a clean, dust-free environment provided with proper ventilation and air-conditioning to
keep the ambient temperature within the specified operating range.
Required operating environment conditions:
−
Ambient:
32°F to 104°F (0°C to 40°C)
