SAFETY AND CE COMPLIANCE .....................................
Before installing and putting this equipment into operation, read these safety instructions and
warnings carefully. Also read and obey all the warning signs attached to the equipment. Make sure
that the warning labels are kept in a legible condition and replace any missing or damaged labels.
WARNING
This equipment contains dangerous voltages
and controls dangerous rotating mechanical
parts. Loss of life, severe personal injury or
property damage can result if the instructions
contained in this manual are not followed.
Only suitably qualified personnel should work
on this equipment, and only after becoming
familiar with all safety notices, installation,
operation and maintenance procedures
contained in this manual.
• Use only permanently wired input power
connections. The equipment must be
grounded (IEC 536 Class 1, NEC and other
applicable standards)
• Use only Residual Current-operated
protective Device (RCD) type B if an RCD is
required
• Wait at least five minutes after the power
has been turned off, before opening the
equipment. The dc-link capacitor remains
charged to dangerous voltages even when
the power is removed. When working on
open equipment, note that live parts are
exposed and do not touch these parts
• Do not connect machines with a three-
phase power supply, fitted with EMC filters,
to a supply via an ELCB (Earth Leakage
Circuit Breaker - see EN50178, section 6.5)
• Note that certain parameter settings may
cause the inverter to restart automatically
after an input power failure
• Do not use this equipment as an
"emergency stop" mechanism (see EN
60204, 9.2.5.4)
• Obey all general and regional installation
and safety regulations relating to work on
high voltage installations, as well as
regulations covering correct use of tools and
personal protective equipment

• Note that the following terminals can carry
dangerous voltages even when the inverter
is inoperative:
Power supply terminals L/L1, N/L2 and L3
Motor terminals U, V and W
Additional terminals
MICROMASTER Eco B+/DC+ and B-
MIDIMASTER Eco DC+ and DC-
• This equipment is capable of providing
internal motor overload protection in
accordance with UL508C section 42. Refer
to P074. Motor overload protection can also
be provided by using an external PTC.
• This equipment is suitable for use in a
circuit capable of delivering not more than
100,000 symmetrical amperes (rms), for a
maximum voltage of 230 / 460 V * when
protected by a time delay fuse *.
* As detailed in the Eco Reference Manual.
• Do not use the unit with a motor of a higher
nominal power rating than the inverter, or a
nominal power less than half that of the
inverter. Only operate the inverter when the
nominal current in P083 exactly matches the
motor rating plate nominal current
• Enter the motor data parameters (P080-
P085) and do an auto-calibration (P088)
before the motor is started.
Unstable/unpredictable motor operation
(e.g. Reverse rotation) may result if this is
not done. If this instability occurs, the mains
supply to the inverter must be disconnected.
• When using the analog input, the DIP
switches must be correctly set and the
analog input type selected (P023) before
enabling the analog input with P006. If this
is not done the motor may start
inadvertently.
• Lowering the fan tray on Frame size C
MICROMASTER Eco exposes rotating
parts. Power must be isolated prior to this
operation.
