3.3.3 Voltage Input / Fuse Protection
The 85-264VAC connection is made via the plug-in screw connections L, N and
.
Primary Side Fuse Protection
The device must be installed in accordance with the provisions of EN 60950. There must be
a suitable separating device external to the power supply capable of switching the device off.
The primary side line protection, for example, is suitable for this purpose.
Further equipment protection is not required because the device is fused internally.
Recommended External Fuse
Automatic cut-out 6A or 10A, Characteristic B (or equivalent in function).
A suitable external fuse is required for DC applications.
If the internal fuse trips (device protection) it is highly likely that the device is
faulty. In this case the equipment should be checked at the factory.
3.3.4 Power LED
The green Power LED enables functions to be evaluated on-site at the control cabinet.
LED lights
Normal power supply operation
LED off
No power supply is available or the device is faulty.
