Operation Manual

Important notices Current Transformer:
• In case only one phase is to be measured, a current transformer can be connected to any socket. The other sockets
must remain empty in this "single phase" operating mode.
• The individual current transformers must be connected to different phases of a three phase system. If more current
transformers are on the same phase, you will get faulty measurements.
• Take particularly care that the locking of the current transformers snaps noticeably when closing.
• In case the thickness of the cable is too large for the current transformer, the use is not possible at this point. Under
no circumstances the CTs shall clamped on a wire with violence.
• The CT cables should not be laid parallel to 230 V/400 V lines.
• The transmitter must be attached to a position where a radio link is possible, e.g, if applicable do not hang it in
cabinets with metal door.
• The cable length of the CTs may not be extended.
• It must be ensured that the load capacity of the sensors is not exceeded. The current transformers are designed
for a maximum of 75 A and an optimum range to 15 A..
