4 How to Use
4-7. Wiring
- 24 -
CAUTION
Be careful not to damage the internal electronic circuit when wiring.
For the cable connected between the indicator part and detector head, use a 1.25 or 2 mm
2
CVV cable (4-core). We will not be liable for any result caused by using an unspecified cable.
Cables used for connecting the indicator/alarm unit and detector head, input power, pump
power and external output should be arranged separately, and they must not run in the same
cable.
The power cables, detector head cables and signal cables must not be installed together with
motor power cables, etc.
Do not use the output for pump power supply for detector head to operate other devices.
Note that only the pumps with the same voltage specification as the input power of the alarm
system can be connected.
For a pump with a different voltage specification, an additional power supply is required.
