BASEPLATE MOUNTING

The baseplate is available in two basic mounting

configurations — horizontal DIN rail mount or vertical

DIN rail mount. Either of these configurations can be

employed internal to, or external to an enclosure;

however, in all cases the DIN rail must be amply

supported, whether by means of metal braces, a

backplate, or a supporting wall.

In addition to DIN rail mounting of the baseplate, a

mounting kit is available for mounting the baseplate

horizontally in a standard, 483 mm (19 in) rack. The

kit provides a 25.4mm (1 in) mounting depth, to meet

clearance requirements at the front of the 19-inch

rack.

Figure 2 shows how baseplate implementation can be

extended using fiber optic cabling. In this

configuration, up to three module Fieldbus segments

can be fiber optic, allowing the baseplates to be

dispersed over a wider area. The FCM2Fs provide

three different fiber optic cabling distances between

baseplates: 2km (1.24 mi), 4 km (2.48 mi), or 10km

(6.2 mi). Refer to PSS21H-2Y3 B3 for additional

information on baseplate implementation using this

configuration.
