5. Preparation for mounting
Gate system
• Ensure that your gate system has an appropriate
electricity supply connection and a facility
for disconnecting the mains. The minimum
cross-sectional area of the earth cable is
3 x 1.5 mm
2
.
• Ensure that all cables are suitable for outdoor use
(UV resistant and cold resistant).
• Check that the gate to be operated fulfils the
following conditions:
- The travel path of the gate must be horizontal,
i.e. on no account sloping.
- When closed, the gate should extend at least
250 mm further than the clear width on the
installation side.
- The gate must have a mechanical gate stop for
both directions.
- The closing edges must be fitted with a flexible
gate seal.
- The gate itself must be straight, so that the
distance between the motor unit and the gate
never changes.
5.2 Checks
Attention!
In order to guarantee correct mounting,
carry out the following checks before
installing.
Supply package
• Check the package to ensure that all the parts are
included.
• Check that you have all the additional components
that are necessary for your particular installation
requirements.
Foundations
• Check the proposed installation location for the
operator system:
- The motor unit and the toothed rack must be
installed on the inside of the gate with the gate
closed.
- The motor unit should not be installed within the
clear width (r)!
- For cantilevered gates, the motor unit must be
mounted at the mid point between the carrier roller
assemblies.
- The foundations must be suitable for heavy-duty
wall plugs.
• Check whether the existing foundations are suitable.
• Check the supply cable.
Pay particular attention to the cable exit point where
the motor unit is to be installed.
