1.9 Maintenance and inspection

If installed in machines, the soft starters must not be commissioned until it
has been determined that the corresponding machines comply with the
safety requirements in Machinery Directive 2006/42/EC. Standard EN 60204
must be complied with within this context. Commissioning is only permitted
if the requirements of the EMC Directive (2014/30/EU) have been observed.
The soft starters of the DS7 series meet the requirements of the Low
Voltage Directive 2014/35/EU and the product standard EN 60947-4-2.
The user is responsible for ensuring that the use of the relevant machines,
as well as the corresponding applications, complies with all applicable EC
Directives. Any other usage constitutes improper use.
At the output of a DS7 soft starter (terminals U, V, W) you must
not
connect any capacitive load (e.g. phase compensation
capacitors),
do not connect any further soft starters (parallel connection
on output side).
Observe the technical data and connection requirements. These are shown
on the rating plate of the soft starter as well as in this documentation.
DS7 soft starters will be maintenance-free provided that the corresponding
general rated operational data, as well as all specific technical data
(→ section 1.7, "Technical data") for the relevant versions, is observed.
However, please note that external factors may have an impact on the
operation and lifespan of DS7 soft starters.
We therefore recommend that the devices are checked regularly and the
following maintenance measures are carried out at the specified intervals.
