Sensitive Circuits
It is essential to define paths
through which high frequency
ground currents flow to ensure that
sensitive circuits do not share a
path with these currents. Control
and signal conductors should not
be run near or parallel to power
conductors.
TE (True Earth) Termination
The converter's TE terminals are
used for all control signal shields
internal to the 1336 REGEN
Converter and must be connected
to the converter's TE
terminals by a separate
continuous lead.

PE (Power Earth) Termination
A safety ground is required by
code. This point must be
connected to adjacent building
steel or a floor ground rod
provided grounding points comply
with NEC and local regulations.

Grounding
All 1336 REGEN components must be connected to system
ground at the PE power ground terminal provided. Ground
impedance must conform to the requirements of national and local
industrial safety regulations (NEC, CENELEC, etc.), and should
be inspected and tested at appropriate intervals. In any cabinet, a
single low-impedance ground point or ground bus bar should be
used. All circuits should be grounded independently and directly.
The AC supply ground conductor should also be connected
directly to this ground point or bus bar.
