DANGER: RISK OF ELECTROCUTION
All electrical parts (including thermistors) are powered by
the power supply. Do NOT touch them with bare hands.
DANGER: RISK OF ELECTROCUTION
Disconnect the power supply for more than 10 minutes,
and measure the voltage at the terminals of main circuit
capacitors or electrical components before servicing. The
voltage MUST be less than 50VDC before you can touch
electrical components. For the location of the terminals,
see the wiring diagram.

NOTICE
We recommend using solid (single-core) wires. If stranded
wires are used, twist the conductor to consolidate the end
or twist the conductor to consolidate the end in
combination with the usage of a round crimp-style terminal
on the end of the conductor. Details are described in
"Guidelines when connecting the electrical wiring" in the
installer reference guide.

Electrical equipment must comply with EN/IEC 61000-3-12, the
European/International Technical Standard setting the limits for
harmonic currents produced by equipment connected to public low-
voltage systems with input current >16 A and ≤75 A per phase.
