Siemens recommended controls cablecable 

Typical cable applications include:

  • sensors
  • actuators
  • control signals
  • extra low voltage power (24Vac/dc)

VSD cable

Setpoint recommends the use of VSD cable when installing all VSDs to help prevent potential EMI and RFI issues.

Specifications:vsdcable

  • tinned copper wire braid
  • low smoke, zero halogen flexible rubber insulation
  • sheath resistant to oil, petrol, acid, sea water and UV light
  • -40°C to +110°C operating temperature
  • high strength rip cord under sheath

NZ regulations are soon to require all installations to use approved VSD cable. Neutral screen is NOT acceptable and approved metal cable glands MUST be used at the motor end.

Isolatorsisolator

If an isolator is required between the VSD and motor, one must be made to comply with the new EMC standards (to be introduced in 2012). A metal gland must be fitted to make the screen continuous going into/out of the isolator and motor terminal box; 3 glands in total will be required. If the isolator is going to be used while the VSD still has a run command, we recommend the isolator’s auxiliary is used to shut the VSD down (via an 18 AWG twisted pair into a DI on the VSD) otherwise 6 full load currents may be applied to the VSD causing it to trip or fail.
