Overview
1.4 Terminal box
Note
Recovery time
Wait for approx. one second after you have removed the connecting cable from the terminal
box before you plug the connecting cable back in.
After power failures of less than one second the connecting cable has to be disconnected.
Division of the system into zones
You can divide a system into several zones or functional areas by using several terminal
boxes, whereby the safety functions can also be set up to be zone-specific. This means that
both enabling switches and STOP buttons can act in only one particular zone and not in
others.
Connection point recognition
You can set an individual box ID for each terminal box. The box ID allows connection point
recognition to be implemented.
Combination of connecting cable and terminal box
It is ensured by mechanical means that only the following combinations can be plugged:
• Mobile Panel 177 DP with connecting cable DP to the terminal box DP
• Mobile Panel 177 PN with connecting cable PN to the terminal box PN
Compatibility with the Mobile Panel 170
You can operate a Mobile Panel 170 on a terminal box DP for the Mobile Panel 177 DP. The
additional features of the new terminal box, for example the box ID, cannot be used with the
Mobile Panel 170.
You can operate a Mobile Panel 177 DP on a terminal box for the Mobile Panel 170.
