73 For Your Safety3 For Your SafetyPlease observe the safety instructions to avoid personal injury and damage to property andthe environment!The BT300 is a safety device! The device must not be opened, interfered with or modified.LAMTEC assumes no liability for damages arising as a result of unauthorised interference!• After commissioning and after each maintenance action check the exhaust gas valuesacross the entire power range.• Qualified specialist staff are required to carry out all activities (assembly, installation, ser-vicing, etc.).• The burner or boiler manufacturer will ensure that the BT300 base unit is compliant withprotection class IP40 or IP54 for outdoor use in accordance with DIN EN 60 529.• Before working in the connection area, switch off the power supply to the plant from allpoles. Ensure that it cannot be switched back on and that the plant is voltage-free. Thereis a risk of electric shock when the plant is not switched off.• Place and secure the protection against contact on the BT300 and on all connected elec-trical parts. The cover must fulfil the design, stability and protection requirements ofEN 60730.• Plug connectors X30 - X34 have no protective separation from the mains voltage. To re-place or disconnect the plug connectors, all poles of the plant must be disconnected fromthe mains.• After each activity (e.g. assembly, installation, servicing, etc.) check the wiring andparameterisation to make sure it is in good working condition.• If the equipment is dropped or suffers impact, you should no longer commission it. Thesafety functions may also be impaired but fail to show any obvious external damage.• When the ratio curves are being programmed, the adjuster will continually monitor thequality of the plant's combustion (e.g. using an exhaust gas analysis station). In the eventthat the combustion values are inadequate or the conditions are potentially harmful, theadjuster will take suitable action, e.g. switch off the system manually.• These operating instructions describe many possible applications and functions andshould be used as guidelines. Carry out functional tests on the test bench and/or in theplant application to ensure correct functioning and document the results.Follow additional instructions to guarantee safety and reliability while operating the BT300:• Condensation and humidity are to be avoided. If necessary, make sure that the installationis sufficiently dry before you switch it on.• Avoid static charge having a destructive effect in case of touching the device's electroniccomponents.NOTICE!LAMTEC recommends that you use ESD equipment while working on electrics/electronics.3.1 Mounting Notes• Please consider protection against contact when installing the BT300. Protection classesas IP 40 - IP 54 are minimum requirements for outdoor use in accordance with EN 60529and therefore obligatory.• The protective cover of the BurnerTronic may only be opened by trained, qualified person-nel.• Make sure that settings for safety-relevant parameters are set in line with the requirementsapplicable to each type of combustion requiring monitoring and conform to the applicable
