4. Structure of Water Leakage Location Detecting System
The water leakage location detecting system consists of:
①
Water leakage location detector
（
AD-AS-1LCM-A
）
②
Water leakage sensor (AD-LS)
③
Break detection terminal (ZT-L2)
For connections on the terminal block, refer to Attached Drawing 2.
Drawing 2 Water Leakage Location Detecting System
5. External Connection
AD-AS-1LCM-A has a terminal block as shown in Drawing 3. (Make connections securely in conformance to Sections 1 to 5.)

AC100
～
240V
（
Variation range in power voltage: AC85
～
264V
）
Before connection, check that the power supply voltage is within the range of use, then, connect it securely to the
terminal block.
*Inputting a power voltage outside the range of use may cause malfunctions and failure of the detector, so care should
be taken.
5-2 Ground Connection
Be sure to ground for interference prevention.
