Preparing the Connection Cable

Always proceed as follows to prepare each connection cable for connection to multipole plugs.
Procedure:
1. Strip 40 mm (1.57 in) of cable sheath from the end of the connection cable to which the
multipole plug is to be attached. When doing so, ensure that no pieces of cable fall into the
enclosure.
2. Strip off 6 mm (0.24 in) of the conductor insulation from each of the required connection
cable conductors.
3. Trim unneeded insulated conductors of the connection cable flush with the cable sheath.
4. Push one bootlace ferrule onto each stripped insulated conductor up to the stop, if necessary.

Connecting Signal Source to Digital Input

Digital signals for active power limitation can be transmitted to the jack X3. A ripple control
receiver or a remote terminal unit can be used as a digital signal source, for example.
