SLM-and user back-up supply input
Voltage: 24V ±20%
Maximum current: 500mA
A current limit in excess of 500mA can result in
damage to the M’Ax.
Auxiliary back-up supply input
Voltage: 27VDC ~ 32VDC (Operation outside these limits will result in
damage to the drive
Maximum current: 1A
This supply is referenced to –DC. For isolation requirements, see Types
of back-up supplies in Chapter 2 Connecting the M’Ax in the User Guide.
For a recommended auxiliary back-up supply, contact the supplier of the
drive.
An auxiliary back-up supply must be isolated from
ground and any other auxiliary back-up supply.
Failure to observe these requirements will result in
damage.

Electromagnetic compatibility (EMC)
This is a summary of the EMC performance of the drive when installed in
accordance with the instructions given in Chapter 2 Installing the drive .
Refer to section 2.32 EMC emission standards - compliance
information on page 21. For full details, the M’Ax EMC Data Sheet can
be obtained from a Drive Centre or distributor listed at the end of this
guide.
Immunity
Compliance with immunity standards does not depend on installation
details. The drive meets EN50082–2 (generic immunity standard for the
industrial environment) and the following specifications from the
IEC61000–4 group (derived from IEC801):
Part 2, Electrostatic discharge: Level 3
Part 3, Radio frequency field: Level 3
Part 4 Transient burst:
Level 4 at the control terminals
Level 3 at the power terminals
Part 5, Surge (at the AC supply terminals):
Level 4 line-to-ground
Level 3 line-to-line (as specified by EN50082–2 informative
annex)
Part 6, Conducted radio frequency: Level 3
Emission
Compliance with emission standards depends on rigorous adherence to
the installation guidelines, including the use of the specified RFI filter in
the AC supply circuit. Compliance also depends on the length of the
motor cable. For full details, refer to the M’Ax EMC Data Sheet which
can be obtained from a Drive Centre or distributor listed at the end
of this guide.
Summary
Conducted and radiated emission meet EN50081–2 (generic emission
standard for the industrial environment) over a wide range of conditions.
This is similar to CISPR11 and EN55011 Class A.
The optional RFI filter, part number 3258-16-45, must be used.
Compliance with EN61800–3 (standard for Power Drive Systems)
Meeting the requirements of this standard depends on the environment
that the drive is to be operated in, as follows:
Operation in the first environment
Observe the wiring guidelines given in the whole of Chapter 2 Installing
the drive , including the section 2.32 EMC emission standards -
compliance information on page 21.
Operation in the second environment
Where the rated input current of the drive system is less than 100A:
Observe the wiring guidelines given in the whole of Chapter 2 Installing
the drive , including the section 2.32 EMC emission standards -
compliance information on page 21.
Where the rated input current of the drive system exceeds 100A:
Observe the wiring guidelines in Chapter 2 Installing the drive ,
excluding the section 2.32 EMC emission standards - compliance
information on page 21.
The second environment typically includes an
industrial low-voltage power supply network which
does not supply buildings used for domestic purposes.
Operating the drive in this environment without an RFI
filter may cause interference to nearby electronic
equipment whose sensitivity has not been appreciated.
The user must take remedial measures if this situation
arises.
If the consequences of unexpected disturbances are
severe, it is recommended that the emission limits of
EN50081–2 be adhered to.
