6.3 Notes on wiring
6 Wiring
Fault current measurement on the FI
Selective FI residual current devices will stop the protective device being
triggered inadvertently.
6.3.1.3 Isolating transformer
Isolating transformer 6- ][Verdr_Schutztrenntransformatoren
The servo amplifier can also be operated via an isolating transformer
when:
` Protection against indirect contact is absolutely essential, despite a
higher leakage current
` An alternative method of contact protection is sought.
For details of how to connect the isolating transformer, please see the
section under “Wiring”.
Fault current Protection
10 - 30 mA Protection against “indirect contact” (personal fire protec-
tion) for stationary and mobile electrical work equipment, as
well as “direct contact”.
50 - 300 mA Protection against “indirect contact” (personal fire protec-
tion) for stationary electrical work equipment
INFORMATION
Recommendation: For protection against direct contact (with
motor cable runs < 5 m), we recommend that each servo ampli-
fier is protected individually using a 30 mA universal current sen-
sitive residual current device.
INFORMATION
We recommend that the cables between the transformer and the
servo amplifier be kept as short as possible.
