Checking on receipt

Examine the state of the material received and its consistency with the content of the order. Should any damage or errors be found on unpacking,
which must be carried out carefully, make the relative notification within and not over 5 days from the receipt of the material. The notification must
indicate the number of the shipping note.
3.

Storage, lifting and weights

The circuit-breaker, protected by an external wooden crate, is fixed by means of screws to the transport pallet or to the bottom of the packing
case. If the circuit-breaker has to remain in the warehouse even for a short time before being put into service, after checking it on receipt, it must
be put back in its container and covered with a waterproof sheet.
Caution
– Use a dry, dust-free room free of aggressive chemical agents as a storage room
– Position the circuit-breaker and any fixed part on a horizontal surface, not in direct contact with the floor, but on a suitable support surface
(Fig. 5)
– The maximum number of stackable circuit-breakers is indicated in figure 6
– Keep the circuit-breaker in the open position and with the closing springs unloaded to avoid unnecessary stresses and the risk of accidents
to the personnel.
