12 Safety
Do not perform any flash test or voltage withstand test on the ACS260 . Any
electrical measurements required should be carried out with the ACS260
disconnected.
Electric shock hazard! Disconnect and ISOLATE the ACS260 before attempting
any work on it. High voltages are present at the terminals and within the drive for
up to 10 minutes after disconnection of the electrical supply. Always ensure by
using a suitable multimeter that no voltage is present on any drive power terminals
prior to commencing any work.
Where supply to the drive is through a plug and socket connector, do not
disconnect until 10 minutes have elapsed after turning off the supply
.
Ensure correct grounding connections. The ground cable must be sufficient to
carry the maximum supply fault current which normally will be limited by the fuses.
Suitably rated fuses should be fitted in the mains supply to the drive, according to
any local legislation or codes
.
Do not carry out any work on the drive control cables when power is applied to the
drive or to the external control circuits.
Within the European Union, all machinery in which this product is used must
comply with the Machinery Directive 2006/42/EC, Safety of Machinery. In
particular, the machine manufacturer is responsible for providing a main switch
and ensuring the electrical equipment complies with EN60204-1.
The level of integrity offered by the ACS260 control input functions – for example
stop/start, forward/reverse and maximum speed is not sufficient for use in safety-
critical applications without independent channels of protection. All applications
where malfunction could cause injury or loss of life must be subject to a risk
assessment and further protection provided where needed.
The driven motor can start at power up if the enable input signal is present.
The STOP function does not remove potentially lethal high voltages. ISOLATE the
drive and wait 10 minutes before starting any work on it. Never carry out any work
on the Drive, Motor or Motor cable when the input power is still applied.
The ACS260 can be programmed to operate the driven motor at speeds above or
below the speed achieved when connecting the motor directly to the mains supply.
Obtain confirmation from the manufacturers of the motor and the driven machine
about suitability for operation over the intended speed range prior to machine start
up.
Do not activate the automatic fault reset function on any systems whereby this
may cause a potentially dangerous situation.
The ACS260 has an Ingress Protection rating of IP20. IP20 units must be installed
in a suitable enclosure.
ACS260 s are intended for indoor use only.
