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 SMART EC 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.
