installation
4.1.1
Transport and unpacking
When transporting the ENS26 isolation unit, pay attention that it is always
protected against contact with dirt and damage through impacts and set-
ting down too hard.
Remove the ENS26 from the transport packaging and pull off the protec-
tive foil, if necessary.
After transport and before installation, check that the ENS26 isolation unit
is in a perfect condition.
4.1.2
Conditions for installation
The ENS26 is intended for installation on a top hat rail in an electrical
cabinet or in a meter cabinet. It cannot be installed anywhere.
The cabinet must be sufficiently large to house the ENS26 and protect the
unit from moisture, dust, dirt and heat.
If there is not enough space in the cabinets available, a separate electrical
cabinet must be mounted to accommodate the ENS26.
Attention
Never position the electrical cabinet containing the ENS26 above or in
the vicinity of a heater. Ensure sufficient ventilation.
The ENS26 should be mounted as near as possible to the mains power
outlet and as far as possible from the electricity feeding source.
Note
These measures reduce the effect of voltage increase by the current
source.
