Note 1
: Wiring should be done using PT100 / PT1000 temperature sensor or double shielded
cables and should be separated from power cables that may cause electrical
interference. Use 3 wires for PT100 / PT1000 if possible. If a 2 wire sensor is used,
jumper the I+ and I- terminals.
Note 2
: Connect FE to
terminal for noise suppression.
Note 3
: Connect the
terminal on both the power supply and the PT04ANNN to the system
ground.
