Mounting position
The devices have to be mounted horizontally with the input terminals on the bottom. In order to ensure a sufficient
convection, the minimum distance to other modules should not be less than 15 mm (0.59 in) in vertical and 25 mm (0.98 in)
horizontal direction.

Preparations:
–
Connect to mains according to the specific national regulations.
–
Power supply cables and unit must be sufficiently fused. A disconnecting device has to be provided for the power supply
to disengage unit and supply cables from supply mains if required.
–
We recommend to choose the cable section as large as possible in order to minimize voltage drops.
–
In order to ensure sufficient air-cooling the distance to other devices has to be considered.
Instructions:
1. Connect the input terminals L and N.
2. Connect the protective earth conductor to terminal o (protection class I).
3. Provide a suitable disconnecting device (e.g. line protection switch) in the supply line acc. to IEC/EN 60950-1.
4. Rate the lines for the maximum output current (considering the short-circuit current) or provide a separate fuse protection.
The input side is protected by an internal input fuse.
5. Observe the polarity.
Connect the 'shield' terminal on the AS-i power supply to the machine ground so that the AS-i system is symmetrically
operated against this machine ground. This improves noise sensitivity in case of symmetrical interference on the AS-i cable.
The device is overload, short-circuit and open-circuit proof. The secondary side of the power supply unit is electrically
isolated from the input.
