DANGER
Wrong or insufficient earthing may result in life-
threatening electric shocks upon contact with
the frequency inverter!
Earth the complete frequency inverter perman-
ently and check the earth contacts at regular in-
tervals!
Prior to any intervention in the device, check all
voltage connections for proper isolation.
NOTICE
Risk of frequency inverter failure caused by
over-voltage!
Always disconnect the frequency inverter from
the circuit to be tested before any high potential
tests or an isolation test on lines in operation!
CAUTION
In operation, the heat sink of the frequency in-
verter will get hot.
Risk of burns upon contact!
Prior to performing work on the frequency in-
verter, disconnect the power supply and wait for
at least 15 minutes until the heat sink has
cooled down.
