7.4.5 Limit switch
The electric cylinder is equipped with two internal limits
switches. When using controllers that are intended for the
electric cylinder, the limit switch prevents an overrunning the
maximum lifting height as well as overrunning the lower
stop position. When using another controller or direct supply
of current, the electric cylinders can extend beyond the limit
switches and lead to their destruction.
7.4.6 Electrical connection "d"
The push rod and the aluminium element surrounding the
push rod are not connected to the protective ground! The
aforementioned parts are considered to be twice as
insulated against primary voltage. The power supply cable
and the 2-button hand switch are connected directly to the
motor housing.
The power supply cable is connected to plug socket
1
and
the 2-button hand switch into socket
2.
The device is ready
for operation after being connected to the mains voltage.
