Installation
To ensure adequate cooling, the device must be installed vertically, with the input and output terminals at the bottom. Be sure to leave a
minimum free space of 40mm ( 1.6in.) above and below the device.
The supply voltage (AC 120/230V) must be connected in accordance with VDE 0100 and VDE 0160. A protective device (fuse) and an
isolating device for disconnecting the power supply must be provided.
The mains switch has to be switched off and prevented from being switched on again before installation or maintenance. If these
rules are not adhered to, contact with live parts or improper use can result in death or severe personal injury.
The voltage selector is to be adjusted by means of a suitable screw driver, in accordance with the respective input voltage.
