1 Safety
1.1 Correct use
This chapter contains general safety instructions, which you
should observe when installing the xM10 function modules.
Severe injury and even death, as well as material losses and
environmental damage, may follow if you ignore safety
instructions.
The xM10 function modules must only be used in combination with
the energy management system (EMS) from Buderus and
components thereof.
The wall-mounted version of the function module has protection
class IP 40, which means that it must not be installed in any area
where there is risk of water spray. The total length of the bus cable
must be no more than 100 m (the extent of the EMS).
For wall-mounted and floor-standing boilers the protection class for
the function module is dictated by the boiler or controller.
We reserve the right to make any changes due to technical modifications.

WARNING!
1.3 Disposal
! The relevant legal requirements must always be observed
when working on electrical installations.
PLEASE NOTE
Only use original Buderus spare parts. Losses caused by the use
of spare parts not supplied by Buderus are excluded from the
Buderus warranty.
Dispose of defunct function modules in an environmentally
acceptable manner, through an approved organisation.

Using the terminals provided, connect the mains supply cable, bus
cable and other components (e. g. pumps, temperature sensors
etc.) to the function module according to the application. The exact
assignment (components - terminals) is shown in the connection
diagrams supplied with the equipment.
! Remove cover from terminal box (Fig. 3, Item 1).
! Carefully take the mains supply cable (Fig. 3, Item 2) and bus
cable (Fig. 3, Item 5) from the boiler's cable harness and
connect them to terminals (Fig. 3, Item 3 and 4) of the function
module.
! Carefully connect other components to terminals (Fig. 3,
Item 3 and 4) on the function module in accordance with the
connection diagram.
If you install a second function module you must bridge the mains
supply cable and bus cable from the first to the second function
module using the cables provided.
PLEASE NOTE
You should ensure that the mains connection is implemented
