Unpacking and Re-packing

When dispatched from the factory, the equipment is packed in accordance with the guide-
lines 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.
The transport packing can be re-used for further transport when applied in the same way.
The storage packing of the individual relays is not suited to 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.
Before initial energization with supply voltage, or after storage, the relay 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

®
SIPROTEC relays should be stored in dry and clean rooms. The limit temperature range
for storage of the relays or associated spare parts is –25 °C to +55 °C, corresponding to
−13 °F to 131 °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 capaci-
tors. The same is valid before the relay is finally installed.
