6.1 PACKAGING
Packaging consists of a paperboard packaging guaranteeing adequate protection for transport and
storage under normal environmental conditions.
The Pro-NX protection relays must be stored within the required temperature limits; the relative
humidity should not cause condensation or formation of frost.
It is recommended that the devices are stored in their packaging; in the case of long storage, espe-
cially in extreme climatic conditions.
It is recommended that the packaging not be disposed of into the environment, but kept in case the
relay should be moved at some later time
6.2 MOUNTING
The Pro-NX protection relays are housed inside metal cases suitable for various kinds of assembly:
Flush mounting
Rack
Flush mounting
The fi xed case, fi tted with special fastening brackets, is mounted on the front of electric control
board, previously drilled as indicated in the drawing.
In case of side-by-side mounting of several relays the minimum drilling distance is determined by
the front dimensions indicated in the overall dimensions drawing, increased by 3 mm, to ensure an
adequate tolerance and gasket space between adjacent relays.
The depth dimension, as indicated in the drawing, must be increased by as much as needed to allow
room for the wiring.
