Safety Instructions
Before installing and putting this equipment into operation, please read these safety instructions and warnings carefully and
all the warning signs attached to the equipment. Make sure that the warning labels are kept in a legible condition and replace
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 suitable 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. The successful and safe operation of this equipment
is dependent upon its proper handling, installation, operation and
maintenance.
·
The MICROMASTER and MIDIMASTER Vector units
operate at high voltages.
·
Only permanently-wired input power connections are
allowed. This equipment must be grounded (IEC 536 Class
1, NEC and other applicable standards).
·
If a Residual Current-operated protective Device (RCD) is to
be used it must be an RCD type B.
·
The dc-link capacitor remains charged to dangerous
voltages even when the power is removed. For this reason it
is not permissible to open the equipment until five minutes
after the power has been turned off. When handling the
open equipment it should be noted that live parts are
exposed. Do not touch these live parts.
·
Machines with a three phase power supply, fitted with EMC
filters, must not be connected to a supply via an ELCB
(Earth Leakage Circuit-Breaker - see DIN VDE 0160, section
6.5).
·
The following terminals can carry dangerous voltages even if
the inverter is inoperative:
- the power supply terminals L/L1, N/L2 and L3 (MMV) - L1,
L2, and L3 (MDV).
-the motor terminals U, V, W.
-the braking resistor terminals B+/DC+ and B-(MMV).
-the braking unit terminals DC+ and DC-
·
Only qualified personnel may connect, start the system up
and repair faults. These personnel must be thoroughly
acquainted with all the warnings and operating procedures
contained in this manual.
·
Certain parameter settings may cause the inverter to restart
automatically after an input power failure.
·
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 230/460V* when protected
by a time delay fuse*.
*As detailed in section 8.
·
This equipment must not be used as an 'emergency stop'
mechanism (see EN 60204, 9.2.5.4).
