Section 7: Commissioning Guide
7.1 Test
Before putting the KSR-Z in normal service the device should be tested for the correct function. This
will be done at site by using a secondary injection test kit. After keeping the required current, on
delay time / trip characteristics and output relays for example the relay should be checked. This is
also applicable for the voltage setting.
7.2 Installation
The KSR-Z device is packed in a separate carton inside an outer packaging. Open the carton
carefully and unpack the device. Also remove the manual included inside the carton. After unpacking
the device make a visual inspection to confirm the KSR-Z is all right.
Check that the measurement voltage, supply voltage and current transformer ratings comply with
the ratings given on the back of the device.
7.3 Connection
The dimensions of the case and the necessary cut-out in the control panel are given in the manual.
Mount the device in the control panel by means of the two mounting clamps included in the carton.
The screw type terminal blocks to connect the KSR-Z device are mounted on the left and right side
on the back. The optional connection for the Modbus via RS485 is also mounted on the back.
The case of the KSR-Z must be grounded to meet protective equipment grounding
requirements. This ground connection is an absolute requirement for a proper
operation.
Connect the supply voltage to the terminal block for the external power supply on the left side of the
back. For this connection a minimum cross section of 1.5mm
2
is required.
Connect the voltage measurement inputs L1, L2, L3, (N) on the right side with your voltage. Please
don’t exceed the maximum voltage. For this connection a minimum cross section of 1.5mm
2
is
required.
