Device technology
®
The ABB i-bus Switch Actuators are modular installation devices for
installation in the distribution board on 35 mm mounting rails to EN 60 715.
The mounting position can be selected as required.
The electrical connection is implemented using screw terminals. The
connection to the bus is implemented using the supplied bus connection
terminal. The terminal designation is located on the housing.
The device is ready for operation after connection to the bus voltage.
Accessibility of the devices for the purpose of operation, testing, visual
inspection, maintenance and repair must be provided compliant to VDE
0100-520).
Commissioning requirements
In order to commission the Switch Actuators, a PC with ETS and an
interface, e.g. USB or IP, are required. The device is ready for operation
after connection to the bus voltage.
The installation and commissioning may only be carried out by qualified
electrical specialists. The appropriate norms, guidelines, regulations and
specifications should be observed when planning and setting up electrical
installations.
•
Protect the device from damp, dirt and damage during transport, storage
and operation.
•
Only operate the device within the specified technical data limits!
•
The device should only be operated in an enclosed housing (distribution
board)!
Manual operation
The 10 A and 16 A Switch Actuators have a manual operating feature. The
Switch Actuators can be switched ON or OFF with an operating element on
the relay. The operating element simultaneously indicates the switch status.
Important
The Switch Actuator does not feature electrical monitoring of the manual
actuation and cannot therefore react to manual operation.
From a power engineering point of view, the relay is only actuated with a
switching pulse if the known relay position has changed. This has the
consequence that after a one-off manual operation, a repeated switching
telegram is received via the bus, and no contact changeover occurs. The
Switch Actuator assumes that no contact changeover has occurred and
that the correct contact position is still set.
An exception to this situation is after bus voltage failure and recovery. In
both cases, the relay position is recalculated in dependence on the
parameterization and set depending on the contact setting.
