3. Connections
The installation description in this chapter follows the EMC
standards and the Machinery Directive.
If the softstarter is temporarily stored before being
connected, please check the technical data for environmental
conditions section 13.3, page 161. If the softstarter is moved
from a cold storage room to the location where it is to be
installed, condensation could appear on the unit. Allow the
softstarter to become fully acclimatised and wait until any
visible condensation has evaporated before connecting any
supply voltages.
Cables
Dimension the mains and motor cables according to local
regulations and the nominal current of the motor. It is
possible to use either copper or aluminium cables.
It is not necessary to use shielded motor cables together with
the Emotron TSA softstarter. This is due to its very low
radiated emissions.
Neither is it necessary to use shielded mains supply cables
for the Emotron TSA softstarter.
For control signal cables it is not mandatory to use shielded
cables to fulfil the EMC regulations (section 1.5, page 6) but
it is recommended in general to avoid disturbances.
