Action
• Determine cause of the insulation fault and eliminate it.
an1
• Determine cause of the insulation fault and eliminate it.
an2
• Check the wiring of terminals L1/+, and L2/- to the IT system
• Press the TEST button
• Check mains voltage
• Check fuses
• Check wiring of terminals E and KE to earth (PE)
• Press the TEST button
• Press the TEST button
• Switch the supply voltage on and off
• Contact Bender Service
• Check mains voltage level and eliminate any existing insulation
faults. After cooling down, the device switches on again automati-
cally at a temperature of 80 °C. This device behaviour is normal if a
high mains voltage and low insulation fault resistance have been
selected.
• Set local date and time
(in case of voltage failure buffer for three days)
