Requirements for SIDOOR ATD4xxW power supply
NOTICE
The DC power supply for the SIDOOR ATD4xxW controller may be used only with firmware
version ATD4xxW > = 1.04.
The following requirements have to be fulfilled by a direct voltage supply provided by the
customer:
Supply voltage
In normal operation a non-grounded SELV voltage according to EN 60950-1: 2014, NFPA
environment UL61010-2-201: 1st Edition 2014 with a typical voltage of 36 V is to be used.
Note 1: Operation of the SIDOOR device is possible down to 19.2V. However, this is
associated with performance loss for the drive with respect to the achievable forces, speeds
and acceleration.
Note 2: With >45V, irreversible damage is done to the SIDOOR device!
In case of a fault scenario of the power supply unit the output voltage of the power supply
unit has to remain smaller than 60 V.
In case of a fault in the SIDOOR controller voltages of up to 60 V can occur.
