EXAMPLE CIRCUIT
The circuit below shows an example applicaion which includes a base-unit that has one PID module and one logic module
fitted.
FS1 Fuse = 1A time lag type to IEC127. CSA/UL rating 250V
FS2 Fuse = 2A time lag type to IEC127. CSA/UL rating 250V
FS3 Fuse = High rupture capacity (HRC). Suitable for maximum rated load current
S1 switch = IEC/CSA/UL approved disconnection device must be used
It is strongly recommended that the power supply zero volts and all logic module zero volts are common to prevent ground
loops.
