Zakład Wytwórczy Aparatów Elektrycznych Sp. z o.o. 1. TRANSPORT 1.1 Unpacking and inspection Immediately after receiving the disconnector it should checked the delivery compliance with the shipping spec- ification. Then should be checked whether the disconnector has not been mechanically damaged during trans- port and the data on the nameplate match the order. - Page 5 Zakład Wytwórczy Aparatów Elektrycznych Sp. z o.o. During transport poles must be secured against tipping over and the central contact should be open. The dis- connector can be transported by means of transport with open cargo area. On flat, hard surfaces it is allowed to move the disconnector’s poles with a pallet truck in the manner shown below, with particular care to prevent the pole from tipping over.

To remove the blockage, unscrew the M10 screw in the disconnector base frame and the M12 screw in the drive lever has to be unscrewed. -
Page 10: Operating Mechanism Assembly
Zakład Wytwórczy Aparatów Elektrycznych Sp. z o.o. 3.4. Operating mechanism assembly The operating mechanism should be mounted on the supporting structure, under driving crank located in dis- connector base. After the operating mechanism is assembled, the coupling shaft must be attached to connect the operating mechanism to the crank. - Page 11 Zakład Wytwórczy Aparatów Elektrycznych Sp. z o.o. Coupling tie rod Tightening torque of M16 screws - 100 Nm. Poles coupling regulation consists of such a setting of the length of the tie rod and coupling lever location ad- justment so that the current paths at each pole reach the limit positions according to the following requirements.
- Page 12 Zakład Wytwórczy Aparatów Elektrycznych Sp. z o.o. Regulation process should be performed in following way: a) Initially coupling tie rods should be installed in such a way that one pole would not be connected (tie rod ending hang on a line below coupling lever); b) Coupling tie rod should be extended or shortened in such a way that current path in driving pole would be achieve require limit positions.
