• Once the supply has been connected the signal supply voltage is internally
distributed to the signal common terminal +VFC for distribution to the eld
contacts. An internal 160mA glass quick blow fuse, 5mm x 20mm, located on
the PSU Card is used to protect the output from eld wiring errors. If external
customer supply is used then a suitable fuse should be tted
WARNING !
Hazardous voltages may exist on the rear panel connections when
connectors are removed. Take care not to touch any exposed parts and
isolate the supply before carrying out any work
WARNING !
For hazardous voltage above 60Vdc (SELV) isolate the supply before
carrying out any work
