Electrical connection

DANGER: RISK OF ELECTROCUTION
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 ex-
ternal main switch, disconnect fuse) and secure against
unintentional restart.
▪ Establishment of the electrical connection and work on
electrical components should only be performed by elec-
trical technicians in compliance with valid standards
and guidelines as well as the specifications of the en-
ergy supply company and the instructions in this manual.
▪ Never make constructional changes to connectors or
other electrical equipment components.
▪ Device covers and service panels must be replaced
as soon as the work is completed.
CAUTION
Increased temperatures may arise in the controller housing
of the Daikin Altherma EHS(X/H) during operation. 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 temper-
ature of 90 °C.
▪ For the following connections, only use cables with a
long-term use temperature ≥ 90 °C: Heat pump outdoor
unit and optional: Electric backup heater (EKBUxx)
CAUTION
If the mains cable of the Daikin Altherma EHS(X/H) is dam-
aged, it must be replaced by the manufacturer or his cus-
tomer service or a similarly qualified person to avoid haz-
ards.
All Daikin Altherma EHS(X/H) control and safety devices are con-
nected ready for use and tested. Modifications on the electrical in-
stallation are dangerous and prohibited. The operator alone shall
bear responsibility for any resulting damage.
