WARNING
¾
This equipment contains dangerous voltages and controls potentially dangerous
rotating mechanical parts. Non-compliance with Warnings or failure to follow
the instructions contained in this manual can result in loss of life, severe
personal injury or serious damage to property.
¾ 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.
¾ The DC link capacitors remain charged for five minutes after power has been
removed. It is not permissible to open the equipment until 5 minutes after the
power has been removed. The drive unit discharges itself during this time.
¾ This equipment is capable of providing internal motor overload protection in
accordance with UL508C section 42. Refer to P0610 and P0335, i 2 t is ON by
default. Motor overload protection can also be provided using an external PTC
or KTY84.
¾ This equipment is suitable for use in a circuit capable of delivering not more
than symmetrical 10 kA (rms) (Frame Sizes A to C) or symmetrical 42 kA (rms)
(Frame Sizes D to GX), for a maximum voltage of 230 V / 460 V / 575 V when
protected by an H, J or K type fuse, a circuit breaker or self-protected
combination motor controller (for more details see Operating Instructions
Appendix F).
¾ Use Class 1 60/75 °C copper wire only with the cross-sections as specified in
the Operating Instructions.
¾ The mains input, DC and motor terminals, can carry dangerous voltages even if
the inverter is inoperative. Always wait 5 minutes to allow the unit to discharge
after switching off before carrying out any installation work.

¾ Please ensure that all of the warning labels are kept in a condition so that they
can be easily read and replace missing or damaged labels.
¾ Maximum permissible surrounding ambient temperature is:
− Frame Sizes A-F:
50 °C at constant torque (CT) and 100 % permissible output current
40 °C at variable torque (VT) and 100 % permissible output current
− Frame Sizes FX and GX:
40 °C at 100 % permissible output current
