Power terminal

Notes
Caution
The supply voltage for the 24 V DC brake (optional) must be drawn from a
power supply unit with safety separation (PELV) in order to safeguard
against accidental voltage transfer in the event of a fault.
It is therefore not permissible to connect any loads with the "extra-low
voltage" degree of protection to the braking circuit.
Caution
The brake must not be fed from the power supply unit of the 24 V DC swit-
ched supply (AUX PWR, black AS-i cable).
