Connector block 1 (SL1) – High voltage terminals
Terminals 1 & 2: Connection of the 230V/ 50Hz power supply (1-L / 2-N)
connected in the factory.
Terminals 3 & 4: Connection of the 230V / 50Hz primary side of the trans-
former (3-N / 4-L)
Terminals 5 & 6: Connection of the 230V / 50Hz lighting (5-N / 6-L)
Terminals 7 & 8: Connection of the 230V / 50Hz lighting „warning light"
(7-N / 8-L)

Terminals 9 & 10:
(Input)
Terminals 11 & 12:
(Output)
13 & 14:
Terminals
(Output)
Connector block 5 (SL5) – Reference switch (for potential -free opening
reed contacts)
The reference switch (reed switch) is pre-assembled and plugged onto the
SL5 plug contacts.
Alternatively, a limit switch can be connected here (see description of in-
puts A-D).
connected in the factory.
Connection of the 24V / 50Hz Secondary side of the trans-
former
(already connected in the factory.)
Optional connection of the 24V DC voltage
Directly connected to terminals 9 & 10 via fuse 20A
Output of the power supply 24V- AC voltage (Standard
power supply of the control board through terminal 9
& 10 with AC voltage / transformer)
Output current 24V- DC voltage
(By battery mode [DC-USV-power supply] of the con-
trol board through terminal 9 & 10)
Output current 24V- DC voltage
max.500mA (13 = Gnd. mass / 14 = +24V)
