Device connection terminal blocks

The AC input and DC output terminal blocks on the front of

the power supply feature Push-in connection technology.

9.1

Input

The power supply is operated on single-phase AC systems

or two outer conductors of three-phase systems. The power

supply is connected on the primary side via the INPUT L/N

connection terminal blocks.

Protection of the primary side

Installation of the device must correspond to EN 61010

regulations. It must be possible to switch off the device using

a suitable disconnecting device outside the power supply.

The line protection on the primary side is suitable for this

(see technical data section).
