4/ INSTALLATION INSTRUCTIONS
e supply voltage 230 V ± 10 % with the rated frequency of 50 Hz must be brought to the
power supply MEg102 through a 200 mA fuse. e phase conductor is to be connected
to the terminal 1 of the double terminal IN and the central conductor to the terminal 2.
e output AC voltage of 170 V
ef
is on the terminals 3 and 4 of the double terminal OUT.
It is galvanically isolated from the network circuits and shall be connected to the power
supply system of the instrument MEg40
+
.
e maximum cross-section of the conductors is 3 mm. e conductors shall be with
double insulation.
