3.10.4 19" rack-mounted housing (21 TE), electrical connection of the inputs and outputs
• For frequencies above 100 Hz, shielded cables are to be used in order to reduce effects from
electrical interferences (EMC).
• Terminal A+ is only operable in the basic version.
• Connect the conductor to the multipolar plug according to the illustration.
• Press the plug into the connector.
3.10.5 Laying electrical cables correctly
1 Lay the cable in a loop just before the housing.
2 Tighten the screw connection of the cable entry securely.
3 Never mount the housing with the cable entries facing upwards.
4 Seal cable entries that are not needed with a plug.
DANGER!
All work on the electrical connections may only be carried out with the power disconnected. Take
note of the voltage data on the nameplate!
