To begin with, all electronical connections have to be established according to the circuit diagrams L1,
L2, L3, T1 (U), T2 (V), T3 (W). The thyristor controller has to be connected to the mains according to the
electric regulations (Low Voltage Directive) so that they can be separeted by disconnecting switches
(e.g. load interrupter, contactor etc.) from the mains.
Cabling must be performed by personnel who are qualified to work low voltage electrical equipment.
Before any connection or disconnection, make sure that the power and control cables and wires are
isolated from the voltage sources.
Recommended connection:
The mains connections, the connection to the load and the control connections have to be laid in sepa-
rate cables. In order to avoid faults the electronic control connections should be separated from the
power wires and/or contactor control wires and one should twist the control wires. In order to reduce
risks related to the effects of electromagnetic interference depending on the installation of the product
please consider the rules for electromagnetic compatibility.
Fuses:
The net-lateral security depends on the recommended and/or the used cross-section of a wire and has
to be made according to DIN 57100 part 430/VDE 0100 part 430/6.81 (Low Voltage Directive).
