There is a reduction in the wiring check time since the wiring can be checked by simply lifting the control terminal cover, which makes maintenance work easier. The control circuit terminals are spring clamp terminals which allow for easy wiring to the control circuit.
The main circuit terminals are screw terminals. Easy wiring is completed by inserting the dedicated blade terminal of each cable. Without using the blade terminal, the loose wires can also be connected using a flathead screwdriver.
The spring clamp terminals provide high reliability since the internal terminal contacts are spring-type.
Therefore, these wires can be protected against loosening or contact faults due to vibrations during operation on a bogie or during transport. It is maintenance free because no additional screw tightening is required.
A specialised coating that conforms to IEC 60721-3-3 3C2/3S2 standards, covers the circuit board to protect the board in hazardous environments and for improved environmental resistance.
