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 capacitors.
The same is valid before the relay is finally installed.
