2.2.2 Power Requirements
The blade's power requirements depend on the installed hardware accessories. If you want to
install accessories on the blade, the load of the respective accessory has to be added to that of
the blade. For information on the accessories' power requirements, refer to the documentation
delivered together with the respective accessory or consult your local Artesyn Embedded
Technologies representative for further details.
The blade must be connected to a TNV-2 or a safety-extra-low-voltage (SELV) circuit. A TNV-2
circuit is a circuit whose normal operating voltages exceed the limits for a SELV circuit under
normal operating conditions, and which is not subject to over voltages from
telecommunication networks.
