Please follow these safety instructions closely toprevent accidents and material losses.
Safety instructions explained
DangerThis symbol warns against the risk of injury.
! Please noteThis symbol warns against the risk of materiallosses and environmental pollution.
NoteDetails identified by the word "Note" contain additionalinformation.
Target group
These instructions are exclusively intended for quali-fied contractors.■ Work on electrical equipment must only be carried
out by a qualified electrician.■ The system must be commissioned by the system
installer or a qualified person authorised by theinstaller.
Regulations
Observe the following when working on this system: ■ National installation regulations■ Statutory regulations regarding the prevention of
accidents■ Statutory regulations regarding environmental pro-
tection■ The Code of Practice of relevant trade associations■ All current safety regulations as defined by DIN, EN,
DVGW, VDE and all locally applicable standardsa ÖNORM, EN and ÖVEc SEV, SUVA, SVTI and SWKI
If you smell flue gas
DangerFlue gas can lead to life threatening poisoning.■ Shut down the heating system.■ Ventilate the installation site.■ Close all doors in the living space.
Flue systems and combustion air
Ensure that flue systems are clear and cannot besealed, for instance due to accumulation of conden-sate or other causes. Ensure a sufficient supply ofcombustion air.Instruct system users that subsequent modifications tothe building characteristics are not permissible (e.g.cable/pipework routing, cladding or partitions).
DangerLeaking or blocked flue systems, or an insuffi-cient supply of combustion air can cause lifethreatening poisoning from carbon monoxide inthe flue gas.Ensure the flue system is in proper workingorder. Apertures for supplying combustion airmust be non-closable.
Extractors
Operating appliances that extract air to the outside(cooker hoods, extractors, air conditioning units, etc.)can create negative pressure. If the boiler is operatedat the same time, this can lead to reverse flow of theflue gas.
DangerThe simultaneous operation of the boiler andappliances that extract air to the outside canresult in life threatening poisoning due toreverse flow of the flue gas.Fit an interlock circuit or take suitable steps toensure a sufficient supply of combustion air.
Working on the system
■ Isolate the system from the power supply (e.g. byremoving the separate fuse or by means of a mainsisolator) and check that it is no longer 'live'.
■ Safeguard the system against reconnection.
DangerHot surfaces can cause burns.■ Before maintenance or service work, switch
OFF the appliance and let it cool down.■ Never touch hot surfaces on the boiler, burner,
flue system or pipework.
! Please noteElectronic assemblies can be damaged by elec-trostatic discharge.Before beginning work, touch earthed objects,such as heating or water pipes, to dischargestatic loads.
Repair work
! Please noteRepairing components that fulfil a safety func-tion can compromise the safe operation of thesystem.Faulty components must be replaced with origi-nal Viessmann spare parts.

Vitogate 300, type BN/MB and its power supply unitare suitable for mounting on a support rail (TS 35 toEN 50 022: 35 x 15 and 35 x 7.5) inside control panels.
Making the LON connection
The Viessmann LON is designed for "Line" BUS topol-ogy with a terminator at both ends (accessories). Fur-ther information can be found in the "Viessmann LONmanual"; see www.viessmann.de/lon.The transfer distances for LON are subject to the elec-trical properties of the respective cable. For this rea-son, only use the specified cable types. Use only onecable type within each LON.Cable types (on site):■ 2-core cable, CAT5, screened■ JY(St)Y 2 x 2 x 0.8 mm (telephone cable)Observe the cabling requirements for the operation ofthe LON interface FTT 10-A (see www.echelon.com).All Viessmann appliances are connected with RJ45connectors. The Viessmann LON always requirescores "1" and "2" plus the screen. The cores are inter-changeable. The installation is therefore reverse polar-ity protected.
NoteWhen connecting devices and routing cables, observethe requirements of safety category II. That is 8.0 mmair and creep paths or 2.0 mm insulation thicknessagainst 'live' components.Ensure the safe electrical separation of all on-site com-ponents (incl. PC/laptops) conforms to EN 60 335 orIEC 65.

Directives
Regulations
Connect the power supply and implement all safetymeasures (e.g. RCD circuit) in accordance withIEC 60364, the connection requirements of your localpower supply utility, and VDE or national regulations.Protect the Vitogate 300 power cable with an appropri-ate fuse.
For oil and gas combustion equipment over 100 kW,according to the Sample Combustion Ordinance"FeuVO", an "emergency stop switch" must be instal-led on site outside the installation room. Observe thenational combustion equipment regulations for yourlocal region. For combustion equipment to EN50156-1, the "emergency stop" installed on site mustcomply with the requirements of EN 50156-1. Fit the"emergency stop switch" outside the installation room.
Install an isolator in the power cable to provide omnip-olar separation from the mains for all active conduc-tors, corresponding to overvoltage category III (3 mm)for full isolation. This isolator must be fitted in the per-manent electrical installation in line with installationrequirements.We also recommend installing an AC/DC-sensitiveRCD (RCD class B ) for DC (fault) currents thatcan occur with energy efficient equipment.
Recommended power cable
3-core cable:■ H05VV-F3G 1.5 mm2
■ H05RN-F3G 1.5 mm2
