Optional Fuse Protection Device
The X57-FUSE device attaches to the
existing terminal blocks of any X57 chassis,
and it provides a duplicate/alternate set of
terminals for connecting the field wiring. The
X57-FUSE device contains up to 4 additional
fuses that are electronically placed in series
with a barrier’s internal fuses. By sizing the
fuses on the X57-FUSE device to values less
than the barrier’s fuse you will protect the
barrier's fuses. The smaller value fuses on the
X57-FUSE device will “blow” first, in the event
of over-voltage or short circuits.

X57-P DIN-32
for Active Barriers
X57-DIN-32
with Ground Bars
for Zener Barriers
The X57-PDIN chassis was designed for use
with X57-600 Series (active) barriers only.
These chassis do not have safety ground con-
nections. Therefore, they can not be used
with zener barriers. Each chassis has a set of
terminals for connecting 24 Vdc power. In
multiple barrier applications, “+” and “-”
power wires must be connected separately to
each chassis or “daisychained” from chassis to
chassis. On large systems, consider using the
surface mount chassis to simplify power
connection wiring.
Note: The X57-DIN-32 and X57-PDIN-32 use 32mm “G” style rails.
These chassis are also available for the 35 x 7.5 mm and 35 x 15 mm
“U” style rails. Order X57-DIN-35 or X57-PDIN-35.
Contact Ronan for availability.
The “DIN” rail chassis options are an ideal
choice to save on panel space. Order one
chassis for each barrier module. With the
X57-DIN chassis (for zener barriers) each
chassis requires its own ground wire. On
multiple chassis installations, the optional
ground bars “buss” together the individual
chassis grounds allowing one ground con-
nection for the entire group. These ground
bars and the ground bar clamps also provide
a convenient spot to terminate cable shields.
Contact Ronan for assistance in specifying
ground bars for your installation. On larger
systems, consider using the surface mount
chassis to simplify ground wiring.
