WARNING!
Touching live parts can result in an
electric shock and lead to potentially
fatal injuries and burns.
Before beginning work on live parts,
disconnect all of the systems circuits
from the power supply (switch off
main switch, disconnect fuse) and
secure against unintentional restart.
The electrical connection and working
on the electrical components should
only be performed by electrical
engineers in compliance with valid
standards and guidelines as well as
the specifications of the energy
supply company.
The equipment covers and mainte-
nance opening covers must be re-
fitted immediately after completion of
the work.
CAUTION!
In the controller housing of the Daikin
Altherma EHS(X/H), in continuous
running, elevated temperatures can be
generated. This can result in currently-
carrying wires from reaching higher
temperatures during operation due to
self-heating. For this reason, these lines
need to have a continuous use tem-
perature of 90 °C.
For the following connections, use
only cables with a long-term use
