4.2.1 115/230 V and 24/48 V Changeover
By means of a jumper inside the unit, the supply voltage can be changed from 230 V
to 115 V, or from 12 V to 24 V respectively. This adaptation must take place before
installing the unit.
Procedure:
Î Insert all connection and supply lines
Î Remove the connecting screw for the Technical Earth
Î Remove the optionally-installed interface card (if present)
Î Undo the four screws on the rear plate, and remove the rear plate
Î Pull the unit one third of the way out of the housing
Î The jumper is easily accessible on the power supply printed-circuit board,
positioned immediately in front of one of the relays and identified by the numbers
1-4 on the board.
Î At delivery, the connector is positioned between contacts 2 and 4
Î To change the unit to 115V or 12 V respectively, contacts 1 and 3 must be
bridged with the connector. Proceed identically when changing from 24V to 12V.
Î Finally, push the unit back into the housing, and screw on the rear plate.
NOTE
If the unit is to be set to the lower voltage, please ensure that the
voltage does not exceed the quoted tolerances, and make a note
on the wiring diagram.
