Power supply
8.1 Direct voltage supply provided by customer
Power supply
Normal operation requires an operational peak current of up to 14A for up to 3s as well as a
continuous current of up to 9A. Smaller current values can result in operating faults,
depending on the selected settings (ramps, end speeds, forces) and the door properties
(friction, weight).
To ensure triggering of the automatic circuit breaker in case of a fault of the SIDOOR
controller, the utilized power supply unit must have the following properties:
● ≥13A continuous current, even in case of a short-circuit
- OR -
● Effective short-circuit current ≤8ARMS, period duration ≤10s, peak current ≤55A
In the case of a fault on the part of the power supply unit or of the SIDOOR controller the
current is limited by the miniature circuit breaker C8 Automat according to EN 60898-1.

Definition of the power supply unit in case of an error of the SIDOOR controller
Fusing
A miniature circuit breaker according to EN 60898-1, 8A, C-characteristic of the type
SIEMENS: 5SY4108-7 or 5SY4108-7KK11 is to be inserted into the supply network by the
customer. It must be ensured that the miniature circuit breaker is only operated within the
permissible range. The miniature circuit breaker must be installed in the vicinity of the
SIDOOR controller at a similar ambient air temperature.
Voltage immunity of the power supply unit at an energetic recovery system
The controller has an energetic recovery system protection.
In the case of a fault the SIDOOR controller will limit the energetic recovery voltage to < 42
V.
Topology specification
The spatial extent of the used supply current circuit must be smaller than 30 m.
Requirements for the supplying mains
The supplied alternating current mains may have a maximum overvoltage category 2
according to EN60950:2014, EN60335-1:2012, NFPA environment UL60101-2-201: 1st
Edition 2014.
