ard from switching on again; check that no voltage is present in
system; earth and short circuit; cover or cordon o neighbouring
live parts;
• Select suitable tool, measuring equipment and, if necessary, per-
sonal safety equipment;
• Evaluation of measuring results;
• Selection of electrical installation material for safeguarding shut-
o conditions;
• IP protection types;
• Installation of electrical installation material;
• Type of supply network (TN system, IT system, TT system) and
the resulting connecting conditions (classical zero balancing,
protective earthing, required additional measures etc.).

For reasons of electrical safety, only the following cables may be used
for connecting to the Homematic IP Wired bus:
• Telephone cable J-Y(ST)Y with 2 x 2 x 0.8
(= 0.5mm²) or 4 x 2 x 0.8 (= 0.5 mm²),
shielded, TP
• Ethernet installation cable S/FUTP, Type Cat5e or higher with 2 x
2 x AWG22 (= 0.34 mm²) or
