WEAR & TEAR
Eco inverters can make possible greatly reduced
maintenance and running costs:
• Fewer stop/start sequences means that
mechanical stresses are reduced.
• Equipment life is extended, and a smaller
number of components require reduced
degree of maintenance
• Reduced airflow means reduced cleaning.
• Reduction in replacement of maintenance
consumables such as fan belts, motor
bearings and fan bearings.

EQUIPMENT RATIONALISATION
Using Eco inverters can significantly reduce the
number of system components and often enable
valuable space to become available:
• Mechanical components which may be
eliminated include dampers, actuators, (and
outstations by using serial communication).
• Reductions in the use of electrical contactors,
control and overload relays, terminals and PID
modules can be achieved. Also, control panel
complexity is reduced, as is wiring and labour
costs.
OUTSTATION CAPABILITY WITH
RS485 SERIAL COMMUNICATION
Remote control capability via RS485 serial link
using the USS protocol with the ability to control
up to 31 inverters via the USS protocol.
