When the installation board(option) is used, fix the board before installing the main unit.
<Installation of Remote Sensor>
Install the remote sensor in a place where E.O. gas may leak and about 20 to 30 cm up from the floor.
NOTE
To install the remote sensor, use the mounting holes on the back of the unit according to the following
procedure. Tighten the screws through one upper mounting hole and one of the two lower mounting
holes.
(1) Open the surface cover of the remote sensor.
(2) Fix the sensor with two screws (M4) through the mounting holes (one upper mounting hole and
one of the two lower mounting holes).
(3) Put the cover back on the remote sensor.
Reason for installing the remote sensor about 20 to 30 cm up from the floor
Since the specific gravity of E.O. gas is greater than air, it tends to stay near the floor if it leaks.
Installing the monitor near the floor is preferred, but it can be easily affected by dirt, dust, water
droplet, etc. Therefore, it is more effective to install it about 20 to 30 cm up from the floor.
