Power supply
6.4 Building DC voltage supply
Fuse protection
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 circuit breaker must be mounted close to the SIDOOR controller at a
similar ambient temperature.
Voltage immunity of the power supply unit at an energetic recovery system
The controller does not have an energetic recovery system protection.
This means the voltage at the terminals increases when the doors are braked. In normal
operation, this voltage is limited to values less than 42V by the ballast circuit integrated in the
controller. In faulty operation, however, this voltage can increase to values of less than 60V.
This must be considered when selecting the supply.
Default topology
Only the SIDOOR controller may be connected to the incoming power supply; additional
consumers are not allowed. The spatial expanse of the used power supply circuit must be
less than 30m.
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.
EMC
Immunity according to EN 61000-6-2:2005, Table 3, Table 3 – Interference immunity – direct
current network inputs and outputs.
Conducted interference emission is not defined for direct current supply according to EN
61000-6-4:2007+A1:2011. If the limits of the 61000-6-4: 2007+A1:2011, Table 2 (Emission –
Low voltage AC mains port) are applied, an appropriate filter must be connected upstream.
Without filters, these limits are exceeded by up to 12dBµV in the range of 150KHz ...
4.6MHz.
The limits can be maintained with an upstream B84112-B-B110 filter, for example, from the
company EPCOS. The cable length between ATD4xxW and the filter must be kept as short
as possible, less than 0.5m. The filter and the ATD4xxW need to be electrically connected
over a common flat metallic structure.
