Operating Instructions
DANGER
!
Hazardous voltage. Will cause death or serious injury.
Turn off and lock out all power supplying this device before
working on this device. Installation and maintenance work on this
device as well as decommissioning may only be carried out by an
authorized electrician.

Notes
Warning
!
When using electrical devices, some of their parts are inevitably
energized. For this reason, incorrect use might lead to death or
serious injuries as well as to considerable property damage. Only
qualified personnel is authorized to carry out work on the device
or in its vicinity. Appropriate transport, professional storage, set-
up and mounting are important to ensure proper and safe
functioning of the device.
Electrostatic sensitive devices (ESD). Only qualified personnel is
authorized to open the device.
Death, serious injuries or considerable property damage
might be the consequence if the warnings are not observed!
Application
The 30 V / 3 A, 5 A, 8 A power supplies with ground-fault detection and
integrated data decoupling are used for operating AS-Interface systems. The
units produce a stabilized 30 V DC voltage with high consistency and low
residual ripple. The output voltage is floating and resistant to short-circuits and
no-load operation. The unit restarts automatically after short-circuits or
overloads. The LED diagnosis is latching and can be deleted using the RESET
function. AS-i + or AS-i – ground faults are detected and only the switched
output 'AS-i + SWITCHED' will be switched off. The ground fault and overload
displays can be reset by pressing the RESET pushbutton or by means of the HI
signal level at the remote reset input (terminal 41 / 42).
The power supply works according to the principle of a primary switched-mode
regulator and can be connected to a 1-phase AC network with 120 V or 230 V,
50 / 60 Hz or a 2-phase AC network with 120 V or 230 V – 500 V at 8 A.
Please observe the relevant DIN / VDE regulations or country-specific
provisions for device installation.
Mounting / Assembly / Connection
The device must be mounted vertically for proper cooling. There should be a
space of at least 50 mm above and below the device.
The supply voltage (120 / 230 V AC) must be connected according to VDE 0100
and VDE 0160 (Fig. III).The network must be fused with a maximum of 20 A
(USA) or 16 A (IEC). An internal fuse is available in the device on the primary
side.
The device is mounted by snapping it on to a 35 mm standard mounting rail
(Fig. I).
All end terminals can be removed.
