Overcurrent Protection; Other Options - Phoenix Mecano M9 Notice D'assemblage

6.2.6 Switching frequency
The electric cylinders of assembly M9 are not been suitable for continuous operation
(100 per cent ED).
The maximum number of double strokes per hour depending on the lifting force and lifting
length are specified in the table.
With ambient temperatures of +40°C or greater, the maximum permissible number of double
strokes per hour is reduced by 30%.
The maximum ambient temperature must not exceed +60°C.

6.2.7 End position limiting
Limit switches are installed in the electric cylinder for limiting the end position.
When commissioning, always ensure that the electric cylinder is switched off in the end position
electrically via the limit switch. The electric cylinder must not be moved to the stop.

6.2.8 Overcurrent protection

The overcurrent protection installed has an internal resistance of 10
When heating from overload, this overcurrent protection switches the high-resistance and
interrupts the electric circuit. In this case, the electric cylinder must be switched off and the error
source remedied. The electric cylinder can be restarted after a cooling period of the overcurrent
protection of at least 2 minutes.
