Power Connections
The enclosure provides two power supply inputs, one
for each of the PSUs fitted. These are IEC320 mains
power connectors suitable for a standard IEC type
power cable, and contain 4A(T) fuses.
Before connecting power to the unit, ensure that the
safety information at the front of this manual has been
followed.
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 power feed to each of the two power supply
modules, as shown in the diagram above.
As a redundancy option, the IQH3B and IQH3BQ enclosures can each support two power
supplies; however, only one PSU is required.
