connectors (top). The Diagnostic Segment Connectors were introduced on carriers

details.

MECHANICAL
4 .1 Mounting Orientation
The F892-CA carriers are designed for mounting on a horizontally aligned DIN-rail on a
vertical surface. This method of mounting ensures optimum heat dissipation from the
F801 Power Modules.
4 .2 Enclosure Requirements
4 .2 .1 General Requirements
The assembly may be mounted in hazardous (classified) areas – see Sections 8 & 9.
The following conditions must also be satisfied to ensure safe and reliable operation.
a) Prevent any form of pollution that could compromise the operation of the unit.
For example, choose an unpolluted location or a suitable enclosure to protect the
assembly.
b) Provide an adequate level of mechanical protection. This can be achieved by
selecting a protected location, a suitable enclosure, or a combination of both.
