SAFETY AND 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 equipment with
covers removed, 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 DIN VDE 0160, section 6.5)
• Note that certain parameter settings may
cause the inverter to restart automatically
once power is restored following an input
supply 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
MICROMASTER Eco. L1, L2 and L3
MIDIMASTER Eco
Motor terminals U, V and W
DC link terminals B+/DC+ and B-
MICROMASTER Eco. DC+ and DC-
MIDIMASTER Eco
• This equipment is capable of providing internal
motor thermal overload protection in
accordance with section 42 of UL508C.
Please refer to P074. An external PTC may
also be used (refer to electrical installation).
• 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 230/460V* when protected by a
time delay fuse*
* As detailed in sections 9.1 and 10.5
respectively.
• Do not operate the motor with a higher
nominal power than the inverter, or a nominal
power less than half 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 analogue input, the DIP
switches must be correctly set and the
analogue input type selected (P023) before
enabling the analogue input with P006. If this
is not done the motor may start inadvertently.
