Use is restricted to the following stated conditions
≤ 45 nF ; a cable length of 10 m is considered.
≤ 50 µH ; a cable length of 10 m is considered.
Details of the correlation between the type of circuit connected, the maximum permissible ambient temperature, the
amb
temperature class, and the effective internal reactance values can be found on the EC-type examination certificate.
