It will certainly be safe then!!!!

Need pick Live up for 24Vdc PSU before going into 24dc Contactor mate.
Done...

Next Limits. Other than what Graeme mentioned is the way you have wired Input from IP-M.? The inputs don't provide Voltage Ref you provide it one. So send 24vdc thru the Relay NO Contact to Input (+) and take Input (-) to 0Vdc.
Cheers Dean I'm on this....wasn't quote sure how the IP-M worked with regards to the inputs, getting it clearer now.
