7.2.3.2 Connecting the 24 V DC supply voltage
The supply voltage is fed in via a 5-pole detachable termi-
nal block.
Important:
Plug and unplug terminal block only with power off!
7.2.3.3 Electrical isolation and notes on earthing
The following illustration shows which circuit parts of the
unit are electrically isolated from each other and which
internal connections exist. Here, both the clearances and
creepage distances and also the test voltages used cor-
respond to DIN/VDE 0160.
The unit is connected via the 6.3 mm Faston terminal (bot-
tom left) to the functional earth (switch-gear cabinet earth)
via a wire with a cross section of 6 mm
2 (also see
Fig. 7.2-6).

19 PE Protective Earth terminal,
connected with the Faston terminal
inside the device.
Do not cause earth loops!
Connect PE and Faston to the
same earthing potential!
