Note:
(1) The residual current monitor is matched with the transformer's own outgoing line.
(2) The wiring of residual current monitor U1 and U2 (1 and 2) is suggested to connect each 6A fuse to
ensure instrument safety.
(3) when the residual current monitoring is not match with 12 transformers, the empty interface I

n should
be connected to the nearby COM with 100Ω resistance, avoid the break line fault alarm.
5.3.2 Wiring method of AID150 centralized alarm and display instrument
A and B are connected to terminals A and B (15, 16) in AIM-R100.The power terminals shall be connected to
the positive pole and ground of the DC24V power supply respectively. The wiring diagram is shown in the figure
below.
DC24V power supply can be selected with 2×1.5mm
2
multi-strand copper wire connection; 2×1.5mm2
shielded twisted pair can be used for external wiring of RS485 communication terminals. COM terminals used for
communication should not be connected.
5.3.3 ACLP10-24 DC24V power supply
Terminals 1 and 2 of the ACLP10-24 DC24V power supply and A1, A3 are the input terminals of AC 220V
power supply, while A3 and A4 are the input extension terminals corresponding to terminals 7 and 8. In the
instrument, A3 is connected with A1 and A4 is connected with A2.V1, G, V2, G corresponding to Terminals 8
and 9, V2, G corresponding to terminals 10 and 11, and V3 and G corresponding to terminals 13 and 14 are the
output terminals of three groups of DC24V power supply, which are used to provide DC24V power for the AID
150 centralized alarm and display instrument. In the meter, all V terminals are connected and all G terminals are
connected.
