2.6 Installing Junction Box PFXC 141

PFXC 141 are normally used for connection of Pressductor

load cells. The cables fixed to the

load cells and the cable to the control unit are to be connected to the junction box.

The junction box PFXC 141 shall be mounted adjacent to the load cells and located in a
protected position easily accessible for service.

The junction box is mounted according to an order-specific drawing.

The dimensions of the junction box are shown in

Figure 2-10

Holes not used must be plugged.

For circuit diagram see

Appendix A.6.4 Junction Box PFXC 141
