4-5. How to wire

3-wire (when the contact is not used) CVVS equivalent 1.25 sq/3-core
5-wire (when the contact is used) CVVS equivalent 1.25 sq/5-core
Detector head installation direction
WARNING

Install the detector head in the specified direction.
Installing it in a wrong direction may cause abnormal readings.

Install the detector while giving due consideration to the conditions for the detection area.
Normally, when the detector is used to detect oxygen deficiency, the detector head should be
installed at a face level.

When there is a risk of oxygen deficiency due to a gas heavier than the air (CO2 etc.), install
the detector in consideration for the specific gravity of the gas.

Do not install the detector in a damp place where condensation occurs. Water drops formed on
the sensor may cause abnormal detection.
CAUTION

Be careful not to damage the internal electronic circuit when wiring. In addition, be careful not
to apply stresses on the detector when (overweight) cables are installed.

The power cables and signal cables must not be installed together with the motor power cables
etc. When these cables must be installed together for unavoidable reasons, put the power
cables and signal cables in a metal conduit. The conduit must be connected to a grounding
circuit.

When stranded wires are used, prevent wires from contacting each other.

Use the dedicated handling lever to wire.

Use appropriate cables to wire.
