Installation notes


Always run the high-voltage ignition cables separate from the unit and other cables
while observing the greatest possible distances

Ensure that the electrical wiring inside the boiler is in compliance with national and
local safety regulations

Mains power must always be supplied via L and N. This means that no potential
differential must exist between the neutral conductor N and protective earth PE

Phase and neutral conductor must not be interchanged (dangerous malfunctions,
loss of protection against electric shock hazard, etc.)

Make certain that strain relief of the connected cables is in compliance with the
relevant standards (e.g. as per DIN EN 60730 and DIN EN 60335)

Ensure that spliced wires cannot get into contact with neighboring terminals. Use
adequate ferrules

Run the high-voltage ignition cable completely separate from all other cables

The burner manufacturer must protect unused terminals of LMV36... and AGM60...
by fitting dummy plugs (exception: X64 (reserved) and X74)

When making the wiring, ensure that the AC 120 V sections is strictly separated
from other voltage sections, thus ensuring protection against electric shock hazard
(for more detailed information, refer to chapter Electrical connection of LMV36... and
AGM60...)

The plugs of connecting line for the LMV36..., must be connected or disconnected
only when the plant is dead (all-polar disconnection), since the BCI does not ensure
safe separation from mains voltage

AGV50... signal cable from LMV36... and AZL2...
Since the BCI carries FELV (refer to chapter Electrical connection of LMV36... and
AGM60...), use of the AGV50... signal cable for connection from the LMV36... to the
AZL2... is mandatory, or observe the respective specification. The cable is specified
for use under the burner hood. When using other types of cable that do not conform
to the specification, protection against electric shock hazard is not necessarily
ensured

Do not lay signal cable AGV50... from the LMV36... to the AZL2... together with
other cables

Service operation with a longer signal cable from the LMV36...:
If a longer signal cable is required for service work for example (short-time usage,
<24 hours), note that the above application under the burner hood no longer applies
and, for this reason, the signal cable can be subjected to increased mechanical
stress. In that case, use a reinforced signal cable

Both the AGV50... signal cable and the AZL2... must be shipped and stored so that
no damage due to dust and water can occur when the products are used in the field

To ensure protection against electric shock hazard, make certain that – prior to
switching on power – the AGV50... signal cable is correctly connected to the AZL2...

The AZL2... must be used in a dry and clean environment

The connection between the actuators and the regulating units for fuel and
combustion air or any other regulating units must be form-fitted
