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. In the following table you will find typical examples of power requirements with and
without accessories installed. For information on the accessories' power requirements, refer to
the documentation delivered together with the respective accessory or consult your local
Artesyn 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 overvoltages from
telecommunication networks.
