Connections

Power Supply
WARNING
Incorrectly executed electrical installations can result in injuries from electrical current and in equipment damage. Direct power supply
Connect the power supply (if required) and implement all grounding measures (e.g. RCD circuit) in accordance with the following regulations:

• In Canada all electrical wiring is to be done in accordance with the latest edition of CSA C22.1 Part 1 and/or local codes. In the U.S. use the National Electrical Code ANSI/NFPA 70. The heating contractor must also comply with both the Standard for Controls and Safety Devices for Automatically Fired Boilers, ANSI/ASME CSD-1, and the Installation Code for Hydronic Heating Systems, CSA B214-01, where required by the authority having jurisdiction.
• Connection requirements specified by your local power supply utility
• Protect the power cable with max. 12A

IMPORTANT
Protect the Vitogate 300 power cable with the appropriate fuse.

Isolators for non-grounded conductors

• The mains isolator (if installed) must simultaneously isolate all non-grounded conductors from the mains.
• If no mains isolator is installed, all non grounded conductors must be isolated from the mains by the upstream circuit breaker.

WARNING
The absence of component grounding in the system can lead to serious injury from electrical current if an electrical fault occurs. Connect the appliance and pipework to the equipotential bonding of the building in question.
WARNING
Incorrect core allocation can result in serious injury and damage to the appliance. Never interchange cores “L” and “N”.
CAUTION
An incorrect phase sequence can cause damage to the appliance. Check for phase equality with the power supply connection of the control unit.

Making the LON Connection

The Viessmann LON is designed for “Line” BUS topology with a terminal end resistor at both ends (accessories). Further information can be found in the “Viessmann LON manual”; see www.viessmann.de/lon.
The transfer distances for LON are subject to the electrical properties of the respective cable. For this reason, only use the specified cable types. Use only one cable 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 of the LON interface FTT 10-A (see www.echelon.com).

All Viessmann appliances are connected with RJ45 connectors. The Viessmann LON always requires cores “1” and “2” plus the screen. The cores are interchangeable.
The installation is therefore reverse polarity protected.
Note: When connecting devices and routing cables, observe the relevant safety requirements. Ensure the safe electrical separation of all on-site components (including PC/laptops).

Commissioning

Integrating the Vitotronic Control Unit into LON

The LON communication module (accessory*) must be installed into the Vitotronic control unit.

• Depending on the relevant control, this may be an additional accessory item.
  Note: The data transfer via LON can take several minute

  Set LON system number, LON participant number and further functions via code

2. Refer to the relevant Vitotronic control unit Service Instructions and the following table.
   Note: In the same LON system, each number an only be allocated once.
   Only one Vitotronic control unit per system may be programmed as the fault manager.

Example: Single boiler system with Vitotronic 300, Vitotronic 200-H heating circuit control unit downstream and Vitogate 300, type BN/MB

Devices required for commissioning:

• PC/laptop with the following equipment:
  – Minimum monitor resolution 1024 x 768
  – Integral or external Ethernet network module
  – PDF Reader

• Supported web browsers:
  – MS Internet Explorer V 7 or higher
  – Mozilla Firefox V 2 or higher
  – Mobile Safari V 3.1 or higher
  – Google Chrome V 18.0 or higher

• Twisted pair network cable

Enabling the DHCP server
Dynamic Host Configuration Protocol (DHCP) makes IP addresses available to clients on request.
If the computer has been set up as DHCP client (standard setting), the DHCP server of the Vitogate 300 can be used to provide an IP address.
Hold down the reset button on the Vitogate 300 for at least 5 sec, but no longer than 10 sec.
The DHCP server has been enabled once the LED LON status flashes green/red alternately.
Note: The DHCP server does not need to be enabled if a manual IP address is to be used.

Creating an Ethernet network
Connect the computer network module by means of a twisted pair network cable with the RJ45 connection of the Vitogate 300.
Creating a connection with the Vitogate 300 configuration webserver
An IP address is automatically assigned to the computer if the DHCP server has been enabled.
If a manual IP address is to be used, make the following settings on the computer:

• IP address: 169.254.0.2 (or higher)
• Subnet mask: 255.255.0.0
• Standard gateway: Leave blank.

For Vitogate 300 equipped with firmware patch, to access the webserver requires the additional step of pressing and holding the reset button for 2 seconds (location of reset button can be found on page 12). The web server will then remain active for 30 minutes, when the 30 minutes expires access to the webserver will be disabled.

Calling up the Vitogate 300 configuration webserver
Open the Vitogate 300 configuration screens:
Start web browser:

• Enter IP address 169.254.0.1 into the address line.
• User name: vitogate
• Password: viessmann\

You can change the password later.
The gateway default screen is called up.
Note: The configuration screens are described in the integral Vitogate 300 online help.
