110-0134.9 / 14 NXAIR / ≤ 40 kA 183
Preparations
The preparations for inserting the contactor truck include:
• Verifying correspondence of truck type / version and panel type / version
• Preparing the operating shaft for the feeder earthing switch
Verifying correspondence of truck type and panel type
To avoid inserting a truck into a panel not suitable for the truck type, verify that you have a
contactor truck at hand and that the present panel is a contactor panel.
To do so, carefully examine both the mimic diagram on the high-voltage door and the front
side of the truck.

Verifying correspondence of truck version and panel version
To avoid inserting a contactor truck into a contactor panel not suitable for the truck type, verify
correspondence as regards (a) coding and (b) mechanical closing latch:
The contactor truck must have the same coding as the panel.
Carefully compare the pair of coding symbols on the top side of
the low-voltage connector with the pair of symbols on the top side of the contactor truck.
