•
Depending on the housing model use supplied stoppers for cable inlets, cut off
necessary cable inlets respectively to the cable diameter. Or alternative use cable
inlet for cable glands. Any cable ducts openings not used must be sealed!
•
The required protective earth connection is established using screws between the
housing parts in metal terminal space covers and housing casings. Commissioning is
only permissible after these screws have been properly attached!
•
Metal screwed-connections are not permitted in plastic housing parts because there
is no potential equalization.
•
Care must be taken to avoid direct radiation from the sun!
•
The device is designed for vertical installation (bottom cable inlet). A horizontal or
reclined installation is only permissible after technical release of the manufacturer!
•
Be sure to observe proper heat dissipation (see Technical data, heat dissipation).
4.2 Minimum space requirement
In order to ensure suf
fi
cient ventilation of the device, clearance on all sides of at least
50 mm has to be maintained to the housing walls, switch cabinet doors, wiring ducts, etc.
The same clearance applies to the installation of several devices next to each other.
When installing several devices on top of each other, the danger of reciprocal heating
exists. This layout is only then permissible when the air suctioned from the upper unit
does not become warmer than the permissible ambient temperature (see Technical
data). I.e., a correspondingly larger clearance or thermal shielding is required.
4.3 Mains connection
The mains connection is made at the terminals: PE, L1, N. In this regard, it is essential to
ensure that the mains voltage lies within the allowable tolerance speci
fi
cations (see
technical data and rating plate af
fi
xed to the side).
The mains voltage must comply with the EN 50160 quality characteristics and the
de
fi
ned standard voltages in IEC 60038!
Danger due to electric current
The integrated autotransformer is not short-circuit-proof; it is essential to note the size of
the internal fuse and the maximum prefuse (see technical data)!
