Instructions for assembling and disassembling ten-pole
X01 and X02 connectors
OPERATING INSTRUCTIONS
General
These operating instructions describe how to assemble and disassemble the ten-pole X01 and X02 connectors. In
doing so, it is possible to wire the upper parts of the ten-pole X01 and X02 connectors in such a way that the low-
voltage interface is connected to the signaling switch in the plug-in unit.

For clearer orientation, the terminal strip is no longer
illustrated in Fig. 2 to Fig. 4.

Note
Nuts and washers may fall into the drive of the SION®
vacuum circuit breaker.
Secure nuts and washers so that they do not fall down.
3. If necessary, secure nuts (x4) and washers (x8)
using a magnetic socket, to ensure that they do not
fall down and disassemble them.
4. Pull the upper parts of the X01 and X02 connectors
upward.

Assembly
Assembly is carried out in reverse order and should be performed using new self-locking nuts (from the accesso-
ries pack).
Tighten the Phillips screws using a tightening torque of 1.4 ±0.1 Nm. Exceeding the tightening torque will result in
damage to the plug flanges.
