4.6.1
Connecting the signalling contacts
There are 4 potential-free contacts in the
nBox
, which are used to transmit information about the status of the
nBox
system. The defined statuses (
ready
,
locked
,
battery fault
,
function test running
) can be assigned to the
signalling contacts as desired via the app. If a change assigned to one of these signalling contacts occurs, the
signalling contact in question is opened or closed.
Using the signalling contacts is optional.
i
Note
When connecting the signalling contacts, the following technical data must be observed:
Loop resistance
Max. 100 Ω
Conductor cross-section
0.75 – 2.5 mm²
Switching voltage
Max. 24 V DC
Switching current
Max. 0.5 A
Connecting signalling contacts
i
Note
The terminal block with the contacts for the signalling
contacts is located in the
nBox
above the
nBox MBC
module.
1. Guide the cable through the membrane gland with strain relief.
i
Note
It is a good idea to strip the cables before inserting
them (approx. 1 cm under the cable gland).
The exposed cores should be a little longer than
needed in order to reach the terminals, and then only
shortened to the actual length needed once they have
been inserted.
2. Connect the conductor to the terminals as shown in the
“Terminal assignment” table.
For more information see Section
3. Connect the signalling contacts in accordance with the plans
for installation on site.
