Trident Planning and Installation Guide
Mounting a Panel
The Trident system is mechanically packaged into functional units that are DIN-
rail-aligned on a panel mount. Each unit comprises one or more modules connected
to a baseplate. Baseplates are concatenated along a DIN rail to form vertical
columns. Each rail can support up to eight units, and several rails can be connected
with I⁄O Extender modules. A daisy-chained bus links signals between units
mounted in a column. An extension bus links signals between columns. A typical
small system may have an MP and several I⁄O modules.
The vertically rail-aligned MP Baseplate measures approximately 9 inches wide by
9.79 inches long per logical slot. Vertically mounted I⁄O baseplates measure
approximately 7.0 inches wide by 9.79 inches long.
The baseplates support hot-insertion of the I⁄O modules and provide primary and
spare slots. Each baseplate (a logical slot) provides field termination connections
for up to 32 points.
All assemblies should be mounted on a 12-gauge (or heavier) steel panel aligned
vertically using DIN 50 022-compatible rails. All DIN system and field power
supplies should be mounted on horizontal DIN 50 022-compatible rails. DIN rails
should be mounted on a 12-gauge (or heavier) steel panel. Clearance should be
provided for adequate air flow around system modules. For typical environments,
provide at least 5 inches (15 cm) of clearance between active modules and the walls
of the enclosure.
Typically, a panel is mounted in a wall-mounted enclosure (for example, a
Hoffman box) or in a floor-mounted enclosure (for example, a Rittal cabinet). The
DIN rails and baseplate assemblies should be located on the panel to allow for the
installation of wiring channels (for example, Panduit) along the left side of vertical
columns and along the bottom of horizontal rails.
For information on dimensions and clearances of baseplates, see:
