Power Requirements
The blade's power requirements depend on the installed hardware accessories. To install the
accessories on the blade, the load of the respective accessory has to be added to that of the
blade. The following table show typical examples of the 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
Emerson 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.
