Power Supply Unit 3A, 5A, 8A
Operating Instructions
Read and understand these instructions before installing, operating, or
maintaining the equipment.
Danger
!
Hazardous voltage.
Will cause death or serious injury.
Turn off and lock out all power supplying this device
before working on this device.
Reliable functioning of the equipment is only ensured with certified components.
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 consider-
able property damage. Only qualified personnel is autho-
rized to carry out work on the device or in its vicinity.
Appropriate transport, proffesional storage, set-up and
mounting are important to ensure proper and safe func-
tioning of the device.
Electrostatic sensitive devices (ESD). Only qualified per-
sonnel is authorized to open the device.
Death, serious injuries or considerable property dam-
age 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 inte-
grated data decoupling are used for operating AS-Interface systems. The units
produce a stabilized 30 V DC voltage with high consistency and low residual rip-
ple. 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 provi-
sions 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.
