3.3 Power Connections
The enclosure provides two power supply inputs, one
for each of the dual PSUs fitted.
These are the IEC320 mains power connectors
suitable for a standard IEC type power cable and
contains a 4A(T) fuse.
3.4 Supply Voltage
The unit automatically senses the nominal supply voltage and sets itself up accordingly. No
voltage adjustment procedure is required.
Each IEC connector supplies an independent feed of power to each of the two power supply
modules as shown in the diagram above.
The IQH3A IQ 3U Modular Enclosure can support dual power supplies for redundancy;
however, this is an option, therefore a second PSU may not be fitted.
Before connecting power to the unit
please refer to the safety warnings at
the front of this manual.
