1.4 PRESCRIBED USE / APPLICATION
Only the correct installation and maintenance by an authorised/qualied company
or person in agreement with the user manual, logbook, check lists and maintenance
lists can ensure the safe operation of the system.
A qualied person is, according to EN 12635, a person who has the required
training, qualied knowledge and practical experience required to install, test and
maintain a sliding barrier system correctly and safely.
1.5 CONFORMITY WITH EUROPEAN DIRECTIVES
The installation complies with the following EU Directives/ regulations:
2006/42/ EC Machine Directive
2014/30 EU EMC Directive (electromagnetic compatibility)
305/2011 EC Construction Product Regulation
The design and production has been executed compliant with the applicable product
standard EN 13241 and the underlying standards EN 12604, EN 12605, EN 12453,
EN 12445, EN 12978 and 12635.
A Declaration of Conformity (DoC) and Declaration of Performance (DoP) are
obligatory for this product. The DoC is included in the Appendix.
1.6 DELIVERY
The barrier, drive and control unit must be installed by a tter or an engineer who
also connects and programs any accessories. The barrier control unit is adjusted to
the options/accessories agreed with the user. The relevant options are laid down
during hand-over.
Optional accessories can be installed afterwards, simply contact the supplier.
Barrier are always delivered fully tested.
1.7 ELECTRICAL CONNECTIONS
Electrical connections must be made compliant with the supplied wiring diagram.
The system must be correctly earthed (Protective grounding in accordance with DIN
VDE).
Because EMC-related suppression components can leak current to the earth cable,
it is advisable that you do not protect the control unit with a Residual Current
Device. When switching on the system, a high starting current can be generated
due to the charging of the intermediate circuit.
If after measurement during commissioning it appears that the leakage current
exceeds the permitted 3.5 mA, an additional grounding, in accordance with EN
60335-1 and IEC 30364-5-54, must be provided. Measurement is made according
to EN 60335-2-103. Consult your installer for this.
Take into account good shielding, for example an automatic circuit breaker 16A B
characteristic.
Ensure that the feeder cables are not carrying power during commissioning.
