If you integrate the blade into your own system, contact your local Artesyn sales representative
for further safety information.
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
Table 2-3 on page 51 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 over voltages from
telecommunication networks.
