WARNING!
Local wiring regulations always take precedence.
Where there are any conflicts between regulatory standards - for example,
earthing requirements for electromagnetic compatibility, safety shall
always take precedence.
Low Voltage Directive
When installed in accordance with this manual, the product will comply with the low voltage directive
2014/35/EU.
PROTECTIVE EARTH (PE) CONNECTIONS
Only one protective earth
conductor is permitted at each protective
earth terminal contacting point.
Unless local wiring guidelines state otherwise, the minimum PE earth conductor should be as follows:
Cross-sectional area of phase conductors ‘S’
(mm²)
Minimum cross-sectional area of PE conductor
‘S
P
’ (mm²)
S ≤ 16
S
16 < S ≤ 35
16
35 < S
S / 2
Note: Values in table assume PE conductor is the same material as the phase conductors
If the PE earth conductor size according to the table above is <10mm² (copper Cu conductor), a second
protective earth connection using a conductor of the same cross-sectional area as the original must be
added. This is due to the current flowing in the Y-Caps being >3.5mA.
EMC Directive
When installed in accordance with this manual the product will comply with the electromagnetic
compatibility directive 2014/30/EU.
The following information is provided to maximise the Electro Magnetic Compatibility (EMC) of VSDs and
systems in their intended operating environment, by minimising their emissions and maximising their
immunity.
Machinery Directive
When installed in accordance with this manual the product will comply with the machinery directive
2006/42/EC.
WARNING!
This product is classified under category 21 of annex IV as ‘logic units to
ensure safety functions’.
All instructions, warnings and safety information can be found in ‘Chapter
8: Safe Torque Off (STO): SIL2/PLd’.
This product is a component to be incorporated into machinery and may
not be operated alone. The complete machinery or installation using this
equipment may only be put into service when all safety considerations of
the Directive are fully implemented. Particular reference should be made
to EN60204-1 (Safety of Machinery - Electrical Equipment of Machines).
