Instructions concerning connection cables
Î
Cables used for connections must be AWG26 - AWG14. Cables used for connections of
longer than 50m must have a cross-section of at least 1mm
2
(AWG16).
Î
We recommend the use of separate power supplies for the safety module and for other
electrical power equipment (electric motors, inverters, frequency converters) or other sources
of disturbance.
