101.5 The socketThe socket of the HPM constitutes a separate component in which the terminals arecontained and the wires connected. The socket is divided by a separator into 2 parts.The left-hand side contains low voltage connections, such as for sensors and 0...10 Vterminals, and the right-hand side contains high voltage connections (230 V) foractuators and pumps.Fig. 1.7: The socketEach section of the socket contains ground multipliers, which are situatedimmediately next to the terminals. Low voltage and high voltage use separate groundsto prevent electromagnetic influence.To fasten the socket to the controller, simply slide the controller onto the socket andpush the two clips on each side of the socket. A screwdriver is required in order toopen the clips again.Fig. 1.8: Cable knockouts and clip to fasten the socketThe cable inlets must be pressed out where needed. The holes are prepared forstandard M-cable glands.Cable inletsClip to fasten socket
