yellow-green wires (grounding wires). J1, J2 relay output
are the dry nodes, which need additional power supply during the control of external load. For example,
J1 controls AC 220V cooling fan, then the AC 220V power supply is needed, and the wiring line type
should be determined according to the load current.

corresponding to the No.11, 12 terminals, the RS485 communication wires corresponding to the No.15,
16 terminals, as well as the CAN communication wires corresponding to the No.18, 19 terminals line

5.3.3 Wiring mode of AIL150-4/AIL150-8 insulation fault locator
Upper row terminals (1-2): 24V, G are auxiliary power supply. Lower-row terminals (21-24,28): H,
L are CAN communication terminals (used for communication terminals connection with medical
intelligent insulation monitor, centralized alarm and display device, and test signal generator).
Lower-row terminals (23,24,28): F1, F2,F3 are used for the loop expansion function of insulation
fault locator. When the number of circuits needed to located is beyond 8 in one set of IT system,
you can simultaneously use three (and three at most) AIL150 series insulation fault locators. When
expanding the second insulation fault locator, the wiring of terminals F1 and F2 needs to be short
circuited; when expanding the third insulation fault locator, the wiring of terminals F1 and F3
should be short circuited. After short circuit connection, the number of branches located by the
second fault locator becomes 9-12 (AIL150-4), or 9-16 (AIL150-8); the number of branches located
by the third fault locator becomes 17-20 (AIL150-4), or 17-24 (AIL150-8).
5.3.4 Wiring mode of AIL160-6 insulation fault locator
The wiring of AIL160-6 is showed as follow, terminals (1-2): 24V, G are auxiliary power supply.
Terminals (21-22): H, L are CAN communication terminals and their expansion terminals.

In order to ensure the normal operation of CAN communication, the CAN interface of each device
needs to be connected by a hand in hand approach, at the same time, the head and end of the
communication bus wire should be connected with a 120Ω matching resistor. The AIL150/AIL160 series
