Unpacking And Re-Packing; Storage And Transport - Siemens 7XV5461-0B 00 Series Directions For Use Manual

Unpacking and Re-packing

When dispatched from the factory, the equipment is packed in accordance with the
guidelines laid down in IEC 60255-21 which specify the impact resistance of packaging.
This packing shall be removed with care, without force and without the use of inappropriate
tools. The equipment should be visually checked to ensure that there are no external traces
of damage.
Please observe absolutely all notes and hints which may be enclosed in the packaging.
Before initial energization with supply voltage, or after storage, the device shall be situated
in the operating area for at least two hours in order to ensure temperature equalization and
to avoid humidity influences and condensation.

Storage and Transport

The FO-Repeater should be stored in dry and clean rooms. The limit temperature range for
storage of the relays or associated spare parts is -40 °C to +85 °C, corresponding to -40 °F
to 185 °F.
The relative humidity must be within limits such that neither condensation nor ice forms.
It is recommended to reduce the storage temperature to the range +10 °C to +35 °C (50 °F
to 95 °F); this prevents early ageing of the electrolytic capacitors which are contained in the
power supply.
For very long storage periods, it is recommended to connect the relay to the auxiliary voltage
source for one or two days every other year, in order to regenerate the electrolytic
capacitors. The same is valid before the relay is finally installed.
For further transport, the transport packing can be re-used when applied in the same way.
The storage packing of the individual relays is not suited for transport. If alternative packing
is used, this must also provide the same degree of protection against mechanical shock and
vibration as laid down in IEC 60255-21-1 class 2 and IEC 60255-21-2 class 1.
