Installing Optional Remote Sensors

301IRFS Sensor
The refrigerant sensor should be installed at the recommended height,
which is 30 cm (1 foot) from the floor.
Communication cables should be 2-24
AWG, twisted and shielded (Belden 9841
or equivalent), which should be connected
in a daisy chain from the 301EM (as
shown).
Power cables should be 14 AWG cable,
maximum length of 60 m (200 ft). The first
four sensor power cables may be wired
directly to the 301EM. Additional sensors
require an external power supply (one per
group of four sensors, to a maximum of 20
sensors in total), using the same rated
cable as units wired to the 301EM.
