Introduction and Safety
Within the European Union, all machinery in which this product is used must comply with
Directive 98/37/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 SRC 311 control input functions (excluding the 'Safe
Torque Free Input') – 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 whilst the input power is still applied.
The SRC 311 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 SRC 311 has an Ingress Protection rating of IP55, and are intended for indoor use only
When mounting the drive, ensure that sufficient cooling is provided. Do not carry out drilling
operations with the drive in place, dust and swarf from drilling may lead to damage.
The entry of conductive or flammable foreign bodies should be prevented. Flammable
material should not be placed close to the drive
Relative humidity must be less than 95% (non-condensing).
Ensure that the supply voltage, frequency and no. of phases (1 or 3 phase) correspond to the
rating of the SRC 311 as delivered.
Never connect the mains power supply to the Output terminals U, V, W.
Do not install any type of automatic switchgear between the drive and the motor
Wherever control cabling is close to power cabling, maintain a minimum separation of 100
mm and arrange crossings at 90 degrees Ensure that all terminals are tightened to the
appropriate torque setting
Do not attempt to carry out any repair of the SRC 311. In the case of suspected fault or
malfunction, contact your local Sales Partner for further assistance.
