1.
Disconnect the LC connector from the SFP transceiver.
2.
Insert a dust protection cap into the SFP transceiver.
3.
Open the bale clasp on the SFP transceiver by pushing it into downward direction with your
index finger. If the bale clasp is obstructed and you cannot use your index finger to open it, use
a small slot-head screwdriver to open the bale clasp.
4.
Pick the SFP transceiver and carefully remove it from the socket.
5.
Install a new SFP transceiver or put a protective cover onto the SFP socket of the switch.
Mounting or Dismounting Separation Wall
Mounting separation wall
To provide clearance distance of 50 mm between the non-intrinsically safe circuits and intrinsi-
cally safe circuits, install the separation walls.
Figure 3.5
1.
Press the separation walls into the provided slots on the front of the switch.
2.
Make sure that they are locked in place.
Danger!
Explosion hazard from wrong separation distances!
If you do not observe the minimum separation distances between intrinsically safe circuits of
associated apparatus and non-intrinsically safe circuits, this can lead to added currents or volt-
ages. This can result in current/voltage flashover generating sparks. The sparks can ignite the
surrounding potentially explosive atmosphere.
Ensure that you observe the compliance of the separation distances to all non-intrinsically safe
circuits according to IEC/EN 60079-14.
