5.7 Connecting the current transformer (winding temperature)
WARNING
Electric shock!
Dangerous high voltages may occur when a
current trans-
former
is operated with an open secondary circuit. This can
lead to death, injuries and property damage.
► Make sure that there are no dangerous electrical voltages on the CT
secondary circuit.
► Never operate a current transformer with an open secondary circuit;
short-circuit the current transformer to prevent this.
► Ground the current transformer on one side.
► Observe the information in the current-transformer operating instruc-
tions.
NOTICE
Damage to the device due to overload!
At a nominal secondary transformer current that is not 2 A, you must also
use a universal multi-ballast transformer (e.g. MESSKO MULTI-BALLAST).
Follow the corresponding operating instructions when doing so.
► Connect the universal multi-ballast transformer in accordance with the
associated operating instructions.
► The device may be operated with an overload of up to 3 A input current
for a maximum of 0.5 hours (in accordance with IEC 354).
