4. Transportation and storage
4.1. Delivery
On delivery, check immediately that the ship-
ment is complete and undamaged. If any parts
are damaged or missing, the transport company
orthemanufacturermustbenotiedontheday
of delivery. Claims made after this date cannot be
recognised. Damage to parts must be noted on
the 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 damage occurring
during transportation 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 tem-
porary 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rmsubsur-
face.
• Our switchgears may be stored at -10 °C to
+50°Catamax.relativehumidityof50%.
The store room must be dry. We recommend a
frost-protected room for storage with a tem-
perature between 10 °C and 25 °C and a relative
humidity of 40% to 50%.
Avoid condensation!
• Seal the threaded cable connections securely to
prevent ingress of moisture.
• Connected power supply cables should be pro-
tected against kinking, damage, and moisture.
