For primary currents > 16 A, this voltage can be dangerous for human beings. An "open mode", i.e. operation of the current transformer without secondary wiring, should be avoided. STW84V 11250-0707-02 Page 5 / 14 www.ziehl.de... -
Page 6: Installation
The polarity of the STWA1 current transformer output (white marking on the cable) must be observed only if several current transformers are connected in series to increase the sensitivity. Attention! Only one current-carrying conductor may be routed through the transformer! STW84V 11250-0707-02 Page 6 / 14 www.ziehl.de... -
