3.4.2 - Specification of the logic output "AOK+/-" (polarized opto-relay output)
The use of the AOK output is mandatory in order to ensure the power supply connection.
It also ensures the protection of the electrical installation against the risk of fire in case of fatal failure of the power
stage (e.g. transistor in short-circuit).
Caution: The opening of the AOK protective branch-circuit may be an indication that a fault has been interrupted.
To reduce the risk of fire or electric shock, the reason for this fault shall be determined and eliminated before
resetting the drive.
Polarized solid state output: closed if drive OK, open if fault.
Pmax = 10 W with Umax = 50 V - Imax = 300 mA.
For UL users, Umax = 42.4 V from an isolated power supply protected by a 3 A UL fuse.
The AOK output is a solid state output: polarity must be observed (see wiring diagram below).
