Installation of additional accessories
▶ Install the additional accessories in accordance with legal
):
requirements and the instructions supplied.
2.10
▶ If required, wipe the casing with a damp cloth. Never use aggressive
or acidic cleaning agents for this.

Danger to life due to current!
Touching live parts can result in an electric shock.
▶ Before installing this product: Disconnect the heat source and all
other BUS nodes from the mains voltage across all poles.
▶ Mount the cover prior to commissioning.
):
3.1
▶ Install the module on a wall, ( Fig. 3 to Fig. 5) at end of document,
on a mounting rail ( Fig. 6) or in an assembly.
▶ Remove the module from the mounting rail
( Fig. 7 at the end of the document).
3.2
▶ Observe current regulations applicable to power connections, and
use at least cable type H05 VV-...
3.2.1
▶ If the conductor cross-sections are different, use the junction box to
connect the BUS nodes.
▶ Switch BUS nodes [B] as shown at the end of the document via
junction box [A] in star ( Fig. 16) or via BUS nodes with 2 BUS
connections in series ( Fig. 20).
If the maximum cable length of the BUS connection between all BUS
nodes is exceeded, or if the BUS system is realised as a ring structure,
the system cannot be commissioned.
Maximum total length of BUS connections:
• 100 m with 0.50 mm
• 300 m with 1.50 mm
▶ To avoid inductive interference: Make sure all low-voltage cables are
routed separately to mains voltage cables (min. clearance 100 mm).
▶ In the case of external inductive interferences (e.g. from PV
systems), use shielded cables (e.g. LIYCY) and earth the shield on
one side. The shield should be connected to the building's earthing
system, e.g. to a free earth conductor terminal or water pipes, and
not to the earth lead terminal in the module.
