Options

By inserting a rechargeable battery (available as an accessory)
alarm signals can be emitted independent of the electricity net-
work in case of a fault. An audible constant tone will be emitted as
an alarm.

Transport and storage

4.1.

Delivery

On delivery, check immediately that the shipment is complete and
undamaged. If any parts are damaged or missing, the transport
company or the manufacturer must be notified on the day of de-
livery. Claims made after this date cannot be recognised. Damage
to parts must be noted on the delivery or freight documentation.
4.2.

Transport

Only the packaging used by the manufacturer or supplier may be
used for transport. This normally precludes the possibility of dam-
age occurring during transport and storage. The packaging should
be stored in a safe place for reuse if the product is frequently used
at different locations.
4.3.

Storage

On delivery, switchgears may be placed into temporary storage for
up to 1 year until use providing the details below are observed.
The following should be taken into consideration for storage:
• Place the packaged switchgear on a firm subsurface.
• The switchgears may be stored from -30 °C to +60 °C at
a max. relative air humidity of 50 %. The store room must
be dry. We recommend a frost-protected room for storage
with a temperature between 10 °C and 25 °C and a relative
air humidity of 40 % to 50 %.
Avoid formation of condensate!
• Seal the threaded cable connections securely to prevent
ingress of moisture.
• Connected power supply cables and attached plugs should
be protected from kinking, damage, and moisture.
