Installation
b. Installation in conjunction with extensions
The flush-mounted insert can be operated via extensions.
Please note the following in this connection:
– The maximum line length depends on the maximum
permissible ripple voltage at the extension inputs.
However, the ripple voltage may not exceed 100 V
(in practice this is equivalent to a minimum line length
of 100 m).
– In order to avoid faults caused by switching operations
of the shutter drives, the motor and extension feeder
circuits must be in separate cables and not laid in the
immediate vicinity of each other (minimum distance
5 cm).
– When calculating the maximum number of units which
can be operated in parallel in one fused circuit, the
current consumption of the motors and the extension
inputs and the power consumption of the UP inserts
must be considered.
