INSTALLING UND CONNECTING THE VT-SSV-1-2X
The dimensions of plug-in switching amplifier VT-SSV-1-2X are given in data sheet
RE 30262.
Assemble the unit using a plastic cable gland PG11 with inserted seal. The
clamping range is 7.6 ... 11.5 mm
The required tightening torque for flat head screw M3 is 0.5 Nm, for clamping
screw M2,6 max. 0.4 Nm.
Proceed as follows to assemble the VT-SSV-1-2X:
1. Loosen the flat head screw and open the cover.
2. Lead the connection cable through the plastic cable gland PG11.
3. Fasten the connection cable with the help of the clamping screws.
4. Tighten plastic cable gland PG11.
5. Close the cover and tighten the flat head screw to the specified tightening
torque.

CONNECTING THE SUPPLY VOLTAGE
1. Disconnect the relevant system part from the power supply.
2. Inspect all cables for intactness.
3. Connect the signal and solenoid cables according to your circuit diagram to the
relevant terminals of the VT-SSV-1-2X.
4. Connect the supply voltage and check the presence of voltage by switching on.
