Cable selection and installation

 

▷

Signal and control line for screw terminals max. 
2.5 mm

2

 (min. AWG 24, max. AWG 12), for spring 

force terminals max. 1.5 mm

2

 (min. AWG 24, 

max. AWG 12).

 

▷

For the ionization and ignition cables, use un-
screened high-voltage cable:

 

FZLSi 1/7 up to 180°C,

 

Order No. 04250410, or

 

FZLK 1/7 up to 80°C,

 

Order No. 04250409.

 

▷

The control lines must be selected in accordance 

with local/national regulations.

 

▷

External electrical interference must be avoided.

 

▷

Do not route BCU cables in the same cable 
duct as frequency converter cables or cables 
emitting strong fields.

Ionization cable, UV cable

 

▷

Cable length:

 

 for internal ignition max. 5 m (16.4 ft), for external 

ignition (double-electrode operation or UV con-
trol) max. 50 m (164 ft); observe the requirements 
of the ignition transformer.

 

▷

The flame signal is adversely affected by EMC in-

fluences.

 

▷

Lay cables individually (with low capacitance) 
and, if possible, not in a metal conduit.

Profibus, Profinet, EtherNet/IP

 

▷

Use only cable and plug components which 
comply with the appropriate fieldbus specifica-
tions.

 

▷

Profibus, Profinet and EtherNet/IP are unen-
crypted fieldbus protocols without authentica-
tion mechanisms.

 

▷

Use shielded RJ45 plugs.

 

▷

Cable length: max. 100 m between 2 subscrib-
ers.

 

▷

Wiring

 CAUTION

Please observe the following to ensure that the 
BCU is not damaged:

–   Burner ground must be connected to the BCU 

in order to avoid uncontrolled spark formation, 
especially in the case of single-electrode opera-
tion.

–   

Different power supply

 for the gas 

valves. The following combinations of BCU 
and LM are allowed: 

 

 

BCU 4xx..E1 + LM..E1:

    

 

power supply via L1, 

 

 

BCU 4xx..E0 + LM..E1:

    

 

power supply via terminal 35,  

 

power supply for air outputs via L1, 

 

 

BCU 4xx..E0 + LM..E0:

  

 

power supply via terminal 35.

–   For use in an ungrounded mains system or for 

mains supply between phases, install an isolat-
ing transformer with single-side grounding.

 

▷

Do not reverse phase L1 and neutral conduc-
tor N.

 

▷

Do not connect different phases of a three-phase 
current system to the inputs.

 

▷

Check the following screw connections for the 
correct tightening torque so as to ensure safe 
grounding of housing, cover, (connection) flange 
plate and electronics unit as well as a good PE 
(ground) wire connection between the BCU and 
burner:
