Siemens LMV51 Series Basic Documentation page 2

Safety notes
Please note:
The present basic Documentation describes the large number of applications and
functions and shall serve as a guideline. The correct functioning of the system is to be
checked and proven on a test rig or on the actual application in the plant!
· Degree of protection IP40 to EN 60 529 for burner controls must be ensured by the burner or boiler
manufacturer by adequately mounting the LMV51...
· In the geographical areas where DIN norms apply, mounting and installation must be in compliance
with the relevant VDE requirements, specifically DIN / VDE 0100, 0550 and DIN / VDE 0722!
· The electric wiring inside the boiler must conform to country-specific and local regulations!
· Ensure that spliced wires cannot get into contact with neighboring terminals. Use adequate ferrules!
· Prior to commissioning, check wiring and the parameter settinfs carefully!
· When commissioning the plant, check all safety functions!
· Before performing any wiring changes or other work in the connection area of the LMV51...,
completely isolate the unit from the mains supply!
· Lay high-voltage ignition cable completely separate from all other cables!
· Ensure protection against electric shock hazard on the LMV51... itself and on all electrical connections
through appropriate mounting!
· There is no absolute protection against incorrect use of the RAST5 connectors.
For this reason, prior to commissioning the plant, check correct assignment of the connectors.
· The burner manufacturer must fit dummy plugs to all AC 230 V terminals that are not used
(refer to «Product range overview» and «Suppliers for other accessories»)
· When wiring the unit, AC 230 V mains voltage and extra low-voltage must always be run strictly
separate to warrant protection against electric chock hazard!
· Protect the mains-powered ionization probe against electric shock hazard!
The LMV51... is a safety device!
· Do not open, interfere with or modify the unit!
· Siemens is not liable for any damage resulting from unauthorized interference!
· In the event of blow n fuses, return the unit to Siemens!
· Check electromagnetic emissions on an application-specific basis!
To ensure the safety and reliability of the LMV51..., the following points must also be observed:
-
Condensation, formation of ice and ingress of water are not permitted!
Should such conditions have occurred, make sure the unit is completely dry again before switching on!
-
Static charges must be avoided as they can damage the unit's electronic components
