62061 / IEC 61508. Refer to the guide supplied with the product for more information.
NOTE!
 It is not possible to assemble the top cover on inverters of frame size A that
have optional safety stop. Thus, it is not possible to raise the protection level
of these inverters to IP21 or Nema1.
 STO function is incompatible with fire mode and bypass functionalities.
7.1.6 24 Vdc External Control Power Supply - CFW701...W1...
The use of this option kit is recommended with communication networks (Profibus, DeviceNet,
etc.), since the control circuit and the network communication interface are kept active (with
power supply and responding to the network communication commands) even in the event of
main power supply interruption.
