It is good practice to protect motors by fitting temperature
sensitive resistors. A typical resistance (up to a reference
temperature of 125
°
C) is 200
Ω
, rising rapidly to 2000
Ω
above this temperature. Connect devices in series between
TH1A and TH1B. Link the terminals if temperature sensors
are not used.

Terminal
Supply protective earth (PE). This terminal must be connected to a protective
(earth) ground for permanent earthing.
