1.4 Obligations of the operator for the safety function
The implemented safety function must be subjected to a regular and documented
performance test by a specialist during the period of use of the machine. The fre
quency of these tests must be determined by the machine operator based on the
specifications of the machine manufacturer.
Check the EMCA at least once per year.

Mounting
Note
Excessive axial and radial forces on the motor shaft can damage the motor.
Comply with maximum permissible shaft loads (
è
The mounting flange offers the following options for fastening:
– Fastening via 4 through-holes for screws of size M6
– Fastening via 4 female threads of size M4 (screw-in depth [mm]: 5).
Observe the assembly instructions for the additional components used
(e.g. axial kit, parallel kit, gear unit, shaft).
The drive must be mounted securely and free of tension.
1. Move the slide or cantilever of the driven mechanical system into a safe posi
tion.
2. Connect the EMCA to the driven mechanical system (

Electrical installation
Caution
Unexpected and unintended movement of the drive during mounting, installation
and maintenance work.
Before starting work: Switch off
power supplies. Removal of the enable signal
at the EMCA is not sufficient.
Secure the power supplies against accidental reactivation.
5.1 Connections and cables
Caution
Unexpected and unintended movement of the drive as a result of incorrectly
assembled cables.
Only use the plug connectors provided and preferably the cables listed in
the specified accessories
è
www.festo.com/catalogue.
Lay all flexible cables so that they are free of kinks and mechanical stress,
e.g. in an energy chain. Observe the instructions for the axis and the additional
components.
ESD protection
At unassigned plug connectors, there is the danger that damage may occur to
the product or to other system parts as a result of ESD (electrostatic dis
charge).
Comply with the handling specifications for electrostatically sensitive
devices.
Seal unassigned plug connectors with protective caps.
Earth system parts prior to installation.
Use appropriate ESD equipment (e.g. shoes, earthing straps).
The plugs for the connectors are included in the scope of delivery (assortment of
plugs NEKM-C).
