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 50mm ( 2in.) 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.
