Isolators for non-earthed conductors
■
Install an isolator in the power cable to provide
omnipolar separation from the mains for all active
conductors, corresponding to overvoltage category
III (3 mm) for full isolation. The isolator must be fitted
in the permanent electrical installation, in line with
installation requirements.
■
We additionally recommend installing an AC/DC-
sensitive RCD, type B
, for DC (fault) currents
that can occur with energy efficient equipment.
Danger
Incorrect electrical installations can lead to seri-
ous injury from electrical current and result in
appliance damage.
Connect the power supply and implement all
safety measures (e.g. RCD circuit) in accord-
ance with the following regulations:
■
IEC 60364-4-41
■
VDE regulations
■
TAR medium voltage VDE-AR-N-4110
Danger
Incorrect core assignment can lead to serious
injury from electrical current and result in appli-
ance damage.
Never interchange cores "L" and "N".
Danger
Incorrect wiring can lead to serious injury from
electrical current and result in appliance dam-
age.
Take the following measures to prevent wires
drifting into the adjacent voltage area:
■
Route extra low voltage (ELV) leads < 42 V
separately from cables
>
42 V/230 V~/400 V~
and secure with cable ties.
■
Only strip the minimum of insulation from
cables as close as possible to the terminals
and bundle tightly to the corresponding termi-
nals.
