B. When installing the power uint on the ceiling,please
layout bushing according to Fig.#9 and thread wire through
the bushing.
Fig.#9: Connection sketch while installing power uint on the
ceiling.
CAUTION: One AC power unit can supply two sensors
at most.
B. 将电源盒放在天花板上，如图示安装电工套管，管
内装入电线。
图9:交流电源盒安装在天花板上的连接示意图。
警告：一个交流电源盒最多可连接两个感应区。
Notice:
a. Keep the connector away from water.
b. Don't mistake the direction of inlet and outlet.
c. Do not connect the DC output of AC power unit to AC
power supply.
d. Do not connect to power supply while installing. Connection
line is not supplied. AC connection wire with insulating
sleeving is recommended. Wire of which the nominal sectionn
area of conductorisnot less than 0.5mm
DC connection line use wire of which the nominal section area
is not less than 0.3mm
requirements (The length of cut wire is recommended less than
10m).
e. The head AC power supply must be protected with
appropriate fuse.
f. Please confirm the AC power supply and water supply should
be shut off before maintaining the products with AC power
related.
3. INSTALL BATTERIES
See Fig.#10
Turn on stop valve. Inspect pipes for leakage in not flushing.
Connect the connector of sensor window with the connector
of solenoid valve.
Remove the battery box cover and insert alkaline batteries
into the battery box.Reinstall the cover of the baottery box
and tighten it with battery box with screws. Connect the
