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 considerable property damage. Only
qualified personnel is authorized 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 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 and 30 V / 2.6 A power supply with ground fault detection and
integrated data decoupling is used to drive AS-Interface systems. The unit produces
a controlled, highly stable 30 V DC voltage with low residual ripple. The output
voltage is floating and short-circuit-proof, and is resistant to no-load operation. The
unit restarts automatically after short circuits or overloads. The LED diagnosis is
saved and can be deleted via RESET. An AS-i + or AS-i – ground fault will be
detected and only the switched 'AS-i + SWITCHED' output will be switched off.
Ground-fault and overload indications can be reset via the RESET pushbutton or via
HI-level at the remote reset input (terminal 41 / 42).
The power supply units function according to the same principle as primary
switching controllers. 3RX9501-1BA00 is suitable for connection to a PELV DC
power supply unit with 24 V DC. 3RX9501-2BA00 is suitable for connection to a
1-phase AC network with 120 V or 230 V, 50/60 Hz.
When installing the units, the relevant DIN / VDE regulations or country-specific
provisions must be adhered to.
Mounting / Assembly / Connection
The unit must be installed vertically for appropriate cooling. There should be a
minimum clearance of 50 mm above and below the unit.
The supply voltage (120 / 230 V AC) must be connected acc. to VDE 0100 and
VDE 0160 (Fig. III). The network must be fused with a maximum of 20 A (USA) or
16 A (IEC).
The units are equipped with a primary-side internal fuse.
They are designed for snap-on mounting on 35-mm standard mounting rails (Fig. I).
All connecting terminals are removable.
