Electrical Connections - baltur TBML 200 ME Instruction Manual For Installation, Use And Maintenance

ELECTRICAL CONNECTIONS

• The power lines must be distanced from the hot parts.
• The burner installation is allowed only in environments with pollu-
tion degree 2 as indicated in annex M of the EN 60335-1:2008-07
regulation.
• Make sure that the power line to which the unit will be connected,
has frequency and voltage values suitable for the burner.
• The three-phase or single-phase power supply line must have a swi-
tch with fuses. The standards also require a switch on the burner's
power line located outside the boiler room where it can be accessed
easily.
• The main line, the relevant switch with fuses and the possible limiter
must be suitable to support the maximum current absorbed by the
burner.
• For the mains supply connection is required an omnipolar switch
with a contact opening gap equal or above 3 mm in accordance with
current safety regulations.
• Refer to the wiring diagram for electrical connections (line and ther-
mostats).
• Remove the external insulating seal of the supply pipe necessary for
the connection, preventing the cable to touch metal parts.
To carry out the connection of the burner to the power supply line pro-
ceed as follows:
• Remove the cover by unscrewing the screws (1), without removing
the transparent door. In this way the burner's electrical panel can be
accessed.
• Loosen the screws (2) and after removing the cable clamp plate (3),
make the 7 pole plug, the 4 pole plug and the modulation control
cable come through the hole. Connect the power supply cables (4)
to the contactor, secure the ground cable (5) and tighten the relating
cable gland.
• Reposition the cable clamp plate. Turn the cam (6) so that the plate
exerts sufficient pressure on the cables, then tighten the screws that
fasten the plate. Finally, connect the related plugs and modulation
command cable, if installed.
