Important notes
Application as directed
The controllers of the 8400 protec series that are equipped with drive−based safety must
not be modified by the user. This concerns the unauthorised exchange or removal of the
drive−based safety.
Danger!
Danger to life through improper installation
Improper installation of safety engineering systems can cause an uncontrolled
starting action of the drives.
Possible consequences:
ƒ
Death or severe injuries
Protective measures:
ƒ
Safety engineering systems may only be installed and commissioned by
qualified and skilled personnel.
ƒ
All control components (switches, relays, PLC, ...) and the control cabinet
must comply with the requirements of ISO 138491 and ISO 13849−2. This
includes i.a.:
– Switches, relays with at least IP54 enclosure.
– Control cabinet with at least IP54 enclosure.
– Please refer to ISO 138491 and ISO 13849−2 for all further requirements.
ƒ
Wiring must be shielded.
ƒ
All safety relevant cables outside the control cabinet must be protected, e.g.
by means of a cable duct:
– Ensure that no short circuits can occur.
– For further measures see EN ISO 13849−2.
ƒ
If an external force acts upon the drive axes, additional brakes are required.
Please observe that hanging loads are subject to the force of gravity!
Danger!
When the "safe torque off" (STO) function is used, an "emergency
switching−off" according to EN 60204 is not possible without additional
measures. There is no electrical isolation, no service switch or repair switch
between motor and controller!
Emergency switching−off" requires an electrical isolation, e.g. by a central
mains contactor!
