Power
The control surface is powered by dual-redundant power supplies which are fitted internally within the frame. To
operate the console, only one of the supplies is required. When both supplies are operational, the load is shared.

PSU Block Location
All of the frame variants are powered from a single PSU block (fitted inside the central bay).
The status of all PSU blocks can be monitored from the Central GUI (via the status bar). To change a faulty PSU,

4.10.3
Mains Connections
The
MAINS
connectors are located on the frame's rear panel. There are two connectors, one for each of the
internal supplies.
For redundancy it is recommended to connect both
MAINS
connectors, each to a separate phase of the AC
mains circuit.
There is no on/off switch, and so the frame will boot as soon as mains power is supplied. It is recommended that
you install a master power switch to control all the power supplied to the frame.
The
MAINS
connectors include an IEC locking mechanism for security. Please unlock before removing a
connector. Be sure to turn the mains power off
BEFORE
connecting or disconnecting a cable.
Each frame
MUST
be connected to the mains using the IEC power cables supplied with the system. When
running with two mains supplies, make sure that both circuits lie on the same ground potential. Otherwise, an
internal bridge of two grounding wires can lead to a ground loop!
