Legend to wiring diagram:
1Supply voltage U
s
(see nameplate) via 6 A fuse
2, 3 Terminals L1, L2 are not connected!
4 Connection to the coupling device AGH675S-7 or the two coupling
devices AGH675S-7MV15:
connect terminal AK to terminal(s) 5 of the coupling device
AGH675S-7 (or the two coupling devices AGH675S-7MV15),
connection with standard low-voltage cable,
maximum voltage at terminal 5: 200 V
5
Separate connection of and KE to PE
6 Separate connection of the terminals 3 and 4 of the AGH675S-7
or AGH675S-7MV15 to PE
7 External TEST button (NO contact)
8 External RESET button (NC contact or wire jumper),
when the terminals are open, the fault message will not be stored
9 STANDBY by means of the function input F1, F2:
When the contact is closed, insulation measurement does not take place.
10 Current output, galvanically separated:
0…20 mA or 4…20 mA
11 Serial interface RS-485 (termination 120 resistor)
12 Alarm relay 1; changeover contacts provided
13 Alarm relay 2 (system fault relay); changeover contacts provided
14 Connection of the coupling device AGH675S-7 to the converter:
connect the high voltage cable encapsulated on one end to the
mid-point of the DC intermediate circuit.
Connection of the two coupling devices AGH675S-7MV15 to the
converter:
connect the high voltage cable encapsulated on L+ and L-.
