Control
2.3 Connection of the control
The following instructions must be observed at connection:
Attention Prevent EMC malfunctions
• Use shielded / drilled cables
• Lay shield on one side of the inverter onto earth potential
• Lay control and power cable separately (about 10...20 cm apart); Lay
crossings in a right angle (in case it cannot be prevented)
• To avoid interferences a separate shielding must be provided for analog
and digital control lines. Depending on the use of the relay outputs, an ex -
tra shielding is to be used, too.
• In case of inductive load on the relay outputs a protective wiring must be
provided (e.g. free-wheeling diode)!
The terminals of the control terminal strip and the transmitter inputs are secu -
rely isolated in accordance with EN 50178.
2.3.1 Assembly of the wires
Required tools:
Screw driver SD 0.4 x 2.5 (DIN 5264)
1. Strip the line about 7 mm
Stranded wire permissible cross-section
rigidly and flexibly 0.08…1 mm
2
(AWG22…18)
7mm
2. Plug screw driver mid into the square slot
3. Plug stranded wire into the round slot, that no wires can be
seen from the outside.
4. Remove screw driver and check if the line is fixed. Make
sure that the stranded wire and not the insulation is clam -
