1.5 Connection BC interface via integrated RJ11
jack (X56)

If the BC interface (jack RJ11) is not used, protection against electric shock hazard
must be provided (jack must be covered up)

The AZL2 signal cable or other accessories like the OCI410 interface (plugged into
the RJ11 jack), may only be plugged in or disconnected when the unit is dead (all-
polar disconnection), since the BC interface does not provide safe separation from
mains voltage

The AZL2 is designed for direct connection to the integrated RJ11 jack on the
LMV37.4

Signal cable from LMV37.4 to AZL2 must conform to certain specifications.
Siemens has specified the signal cable for use under the burner hood. When using
other signal cables, it is not guaranteed that the required cable features will be met.

Do not lay the signal cable from the LMV37.4 to the AZL2 together with other
cables. Use a separate cable

Service operation with a longer signal cable from LMV37.4 to AZL2
If a longer signal cable is required for service work, for example (short-time, <24
hours), note that the above usage under the burner hood no longer applies and, for
this reason, the signal cable can be subjected to increased mechanical stress. Extra
cable sheathing is therefore required

Both the signal cable and the AZL2 must be shipped and stored so that no damage
due to dust and water can occur when used in the plant later on

To ensure protection against electric shock hazard, make certain that, prior to
switching on power, the signal cable is correctly connected to the AZL2

The AZL2 must be used in a dry and clean environment
Connection interface OCI410 on the BC interface
Connect the OCI410 interface without other extension with the USB interface at your
PC, follow the example design below.
