Make sure that supply voltage is switched off!
This section describes how to connect the electrical
connections to the Arc Monitor and to the Arc Guard
System.
Connecting HMI;
See: "Mounting the HMI" on page 20.
Connecting optical detector
See: "Connecting optical detectors" on page 23.
Connecting extension module (option)
See: "Connecting extension module (option)" on
page 24.
Connecting Current Sensing Unit (option)
See: "Connecting CSU cable" on page 24.
Electrical connections are:
1. Internal Relay Fault, ( IRF, K1)
2. Trip Signal relays, ( K2, K3)
3. Trip contact, (K4, K5, K6)
4. Power supply
They are situated on top of the Arc Monitor.
Connecting the Arc Monitor
WARNING
Make sure that supply voltage is switched off!
First connect the trip signal relays and trip contacts.
Follow the steps below:
1. Connect wires for Internal Relay Fault, IRF, trip
signal relays (K2, K3) and trip contacts (K4, K5, K6).
2. Use a torque of 0.5 NM
3. Use a screwdriver 2.5 x 0.6 mm (0.98 x 0.23 inches)
4. Cable area 0.2 - 2.5 mm² (0.078 x 0.98 inches²).
5. Connect cable for IRF, K1 to terminal number,
14,12,11.
6. Connect cable for K2 to terminal number 24, 22, 21.
7. Connect cable for K3 to terminal number 34, 32, 31.
8. Connect cable for K4 to terminal number 43, 44.
9. Connect cable for K5 to terminal number 53, 54.
10. Connect cable for K6 to terminal number 63, 64.
