1. SAFETY AND CE COMPLIANCE
Before installing and operating this equipment 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 must be installed, operated and maintained by suitably qualified
personnel only.
Use only permanently-wired input power connections. The equipment must be grounded
(IEC 536 Class 1, NEC and other applicable standards).
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.
Some parameter settings can start the motor automatically when power is restored after
a mains failure.
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).
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
stopped:
Power supply terminals
L1, L2 and L3
Motor terminals
U, V and W.
When using the analogue input, the jumpers 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.
This equipment is capable of providing internal motor overload protection in accordance
with UL508C section 42.
This equipment is suitable for use in a circuit capable of delivering not more than 10,000
symmetrical amperes (rms), for a maximum voltage of 240V/480V/500V when protected
by a time delay fuse (see Electrical Data for details).
Do not operate the equipment in direct sunlight.
This equipment must not be used as an ‘emergency stop’ mechanism
(see EN 60204,
9.2.5.4).
