5 Storage and Transport
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.
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 1 and IEC 60255–21–2 class 1.
The Lithium-batteries in our equipment are subject to Special Provision
188 of the UN Recommendations on the Transport of Dangerous Goods
Model Regulations and Special Provision A45 of the IATA Dangerous
Goods Regulation and the ICAO Technical Instructions. This is only valid
for the original battery or original spare batteries.

Connections of the Current Terminals
Fixing Elements
The fixing elements for the transformer connection are part of the current
terminal (housing side). The head shape of the terminal screw allows for
using a flat screwdriver (5.5 mm x 1.0 mm / 0.21 in x 0.039 in) or a crosstip
screwdriver (PZ2). PZ2 is recommended.
Cable lugs and Wire Cross-sections
There are two connection options: the connection of single wires and the
connection with a ring lug. Only copper wires may be used.
We recommend ring lugs with the following dimensions:
Figure 6 Ring lug
For complying with the required insulation clearances, insulated ring lugs
have to be used. Otherwise, the crimp zone has to be insulated with cor-
responding means (e.g. by pulling a shrink-on sleeve over).
We recommend ring lugs of the PIDG range from Tyco Electronics.
Two ring lugs can be mounted per connection.
