30 Option description and instructions
Wiring
One emergency stop button and one reset button are installed on the cabinet door and
wired to the FSO module at the factory. There are double contacts in the emergency stop
button and double wiring (two-channel connection) between the button and the FSO
module. This function must be used in a redundant manner, that is, the emergency stop
button must be connected to both terminals with a separate contact.
There is an extension terminal block [X68] for the connections to the FSO module inside
the drive cabinet.
The FSO module connectors [X113] and [X114] have been wired to
[X68]. This table shows the connections between the extension terminal block and the
FSO module.
If necessary, install additional
emergency stop buttons on site. See the table above and
the circuit diagrams of the delivery. Obey these general rules:
1. Use only double-contact buttons approved for the emergency stop circuits.
2. Connect the emergency stop buttons with two conductors (two-channel connection).
Note:
Keep the channels separate. If you use only one channel, or if the first and
second channels are connected together (for example, in a chain), the cross-fault
detection of the FSO module trips and activates the fault reaction function (see
page
) as it detects a redundancy failure.
Note
: If you change the input and the parameter settings in the FSO module into a
one-channel implementation, it affects the safety integrity of the safety function. The
safety data that ABB has calculated for the function is not valid.
3. Use a shielded, twisted pair cable. We recommend a double-shielded cable and gold-
plated contacts in the emergency stop button.
4. The maximum allowed cable length between the drive and
the emergency stop button
(for the whole loop)
is 250 m (820 ft).
5. Obey the general control cable installation instructions given in the hardware manual
and in the FSO module user’s manual.
