INSTRUMENT CONECTION
The instrument supply leads should not be in proximity of the incoming low-potential signals.
Contactors, motors with larger input power should not be in proximity of the instrument.
The leads into the instrument input (measured quantity) should be in sufficient distance from all power leads and appliances.
Provided this cannot be secured it is necessary to use shielded leads with connection to ground (bracket E).
The instruments are tested in compliance with standards for use in industrial area, yet we recommend to abide by the above
mentioned principles.
Relay parameters specified in the technical data
apply for resistance load. Upon connection of the
induction load we recommend to fit the leads to relay
1 A with a fuse for maximum load protection.
Grounding on terminal „E“ must be connected
at all times
