Terminal Description
50
Positive supply Voltage, 24V ±20%, referred to pin 51
51 Ground potential for supply voltage
52 Protective ground
The ground terminals 8 and 51 are internally connected together.
Ground and protective ground are internally connected via a 1k Ω resistor. The resistor will thermally withstand a
potential difference of up to 30V between PE and GND but for proper operation this difference should be limited to
5V.
3.2.4.2 100 to 240V AC Mains Supply
The AC version of the TCE requires a nominal power supply of 100 – 240V AC and operates over a range of 90 –
264V AC.
The power supply input of the TCE is protected by a 1A slow blow fuse. As a protection against fire in case of a
short in the supply cable, the output of the power supply must be equipped with a fuse with a rating not higher
than the current carrying capacity of the cable used.
For the mains powered units a good connection of PE is mandatory. The cross section of the PE cable should be
at least the cross section of the supply cable or 1mm², whichever is higher.
Connect the supply to terminal 91 (neutral) and 90 (life). (See Fig. 17)
