3.4 Wiring

All connections for the ENT-DC are made in the front.
All clamps are also directed to the 19" header for the 19" flush type version. Hence connections can be made in
the rear or combined in front and rear.

Note
If connections are made in the front and rear the same
signals should not be assigned in the front and rear at
the same time. Proper operation of the ENT-DC may be
endangered in this case. (Issues with respect to safety
are not impacted).
