Delivery and Storage
Attention
Avoid damaging the porcelain bodies.
4.2.1 Packing
The circuit-breaker is supplied as pretested modular assembly.
If transported by land, the components are delivered in crates. If transported by container (by sea), some are
supplied on pallets and some in crates.
All components and parts required for commissioning and operation are included in the shipment in a separate
package.
The parts comprised in the transport unit are indicated in the checklist provided with every circuit-breaker.

gas is supplied in cylinders.
The electrical circuit-breaker control is wired to the terminal strip in the control cubicle.
4.2.2
Checking on Arrival
When a shipment arrives it should be checked immediately against the dispatch notes and check list. If it shows
signs of damage determine the extent of the damage and its probable cause without delay. Should the damage
have been caused in transport, call in a representative of the forwarding agent in order to record the facts. This is
an essential requirement if a claim for damages is to be submitted.
4.2.3 Storage
If a circuit-breaker is not to be assembled immediately after delivery, the crates can be stored outdoors.
For better ventilation and as a protection against ground dampness, the crates should then be placed on wooden
planks and covered with tarpaulins.

Note
In case of storing the circuit-breaker longer then 3 months the anti-condensation heater in the
control cubicle and on the operating mechanism cubicles must be switched on.
