• Ensure that the phase sequence of the feeders is correct.
• Use 10 A Diazed fuses for the feeders.
• Additional enable is possible via external switch on terminals 7 and 8 for switch-on of normal
mains supply. Remove the plug-in jumper in this case.
• Additional enable is possible via external switch on terminals 20 and 21 for switch-on of emer-
gency supply, e.g. for enable signal following generator start-up. Remove the plug-in jumper in
this case. Generator startup must be completed before giving switchover clearance.
