Infrastructure & Citiies Sector 1 Safety notes 25.09.2013
1.3.1 Use of the AGM60...
To ensure correct fuel changeover, output
Safety valve (SV) / magnetic clutch
(X6-03 pin 3) must be connected to the respective input of the AGM60... (X32-
01 pin 5), the reason being the following:
Depending on the signal level at this output, the AGM60... sends the point in
time for fuel changeover to the LMV36...
Caution!
The AGM60... must always be powered via the LMV36... basic unit and never
directly by mains voltage
The live conductor for fuel changeover (refer to chapter Fuel changeover) must
always be picked up at terminal X31-01 pin 4 of the AGM60…
Connecting cable between LMV36... and AGM60... (also refer to chapter Makeup of
system): Use of this connecting cable is mandatory (available as an accessory item,
refer to chapter Type summary)
1.4 Electrical connections of LMV36... and
AGM60...
For LMV36... and AGM60..., the following low-voltage categories are in use:
SELV (safety extra low-voltage) and PELV (protective extra low-voltage) ensure
protection against electric shock hazard
FELV (functional extra low-voltage)
Functional extra low-voltage without safe separation provides no protection, so that
risk would not be excluded in the event of failure

Note
The safety class of the connected components determines whether SELV or PELV
applies. In the case of PELV, the respective component is earthed and connected to
protective earth.
