Thermistor inputs
Name Terminal block Connector Item
TH1 — CN20 Thermistor (Room temp.) (Option)
Ensure to wire thermistor wirings away from the power line and/or OUT3 to 13 wirings.
Do not splice the wiring to extend or shorten it, otherwise this could affect correct monitoring of each temperature.
If the wiring is too long, bundle it with a strap to adjust the length in the cylinder unit.(see the photograph on the right)
*1. The maximum length of the thermistor wiring out of the cylinder unit is 5 m.
When the wires are wired to adjacent terminals, use ring terminals and electrically insulate the wires.

connected and prevent the FTC from being applied with static electricity (e.g. touch a case body etc.).
Otherwise, it may cause a failure of the FTC due to the static electricity.
