W !
ARNING
According to the EEC standards the SM32 and accessories must be used only after checking
that the machine has been produced using those safety devices required by the 89/392/
EEC set of rules.
Drive systems cause mechanical motion. It is the responsibility of the user to insure that
any such motion does not result in an unsafe condition. Factory provided interlocks and
operating limits should not be bypassed or modified.
Never open the device or covers while the AC Input power supply is switched on. Mini-
mum time to wait before working on the terminals or internal devices is 5 minutes.
If the front plate has to be removed because the ambient temperature is higher than 40
degrees, the user has to ensure that no occasional contact with live parts will occur.
Always connect the Drive to the protective ground (PE) via the marked connection termi-
nals (PE2) and the housing (PE1). Adjustable Frequency Drives and AC Input filters have
ground discharge currents greater than 3.5 mA. EN 50178 specifies that with discharge
currents greater than 3.5 mA the protective conductor ground connection (PE1) must be
fixed type and doubled for redundancy.
The drive may cause accidental motion in the event of a failure, even if it is disabled,
unless it has been disconnected from the AC input feeder.
W ! - ELECTRICAL SHOCK AND BURN HAZARD :
ARNING
When using instruments such as oscilloscopes to work on live equipment, the oscilloscope's
chassis should be grounded and a differential amplifier input should be used.
Care should be used in the selection of probes and leads and in the adjustment of the
oscilloscope so that accurate readings may be made. See instrument manufacturer's
instruction book for proper operation and adjustments to the instrument.
W ! - FIRE AND EXPLOSION HAZARD :
ARNING
Fires or explosions might result from mounting Drives in hazardous areas such as locations
where flammable or combustible vapors or dusts are present. Drives should be installed
away from hazardous areas, even if used with motors suitable for use in these locations.
