3. Can the PILZ relay contacts handle the VFD supply current ?
4. Can the PILZ relay contacts handle the 70V PSU input current ?
Hi Eddy,
1. I have gone through manual and agree so I have amended the design.
2. Well Dean has responded to this, so I guess its a matter of personal choice.
3 & 4. Now this is getting a bit deep for me, but if I am reading the Pilz documentation correct the safety contacts can handle 240VAC and 8 amps, but I stand to be corrected.

Thanks for your help
Jim
