Perform the installation procedures of both drive units as explained in
chapter 3. At the end of the mechanical installation, refer to the following
procedure:
Remove the service bracket, ref.
fig. 11, from both drive units,
and keep it;
When the service bracket has been removed, take
great care NOT TO MOVE the transmission crowns
of the operators in order not to compromise the
positioning of the screws of the travel-limit devices.
Open the cover of both travel-limit units;
Remove the power cable of the SLAVE drive unit and make the
connections as indicated in figure 21;
Close the cover of both travel-limit units and reposition the service
brackets.
Continue the installation performing, only for the MASTER operator, the
instructions given from chapter 5 on page 6.
Therefore the travel-limit devices will be adjusted only on the MASTER unit
as described in chapters 6 and 6.1.
The electro-brake can be installed independently on the MASTER or
SLAVE unit.
