Foxboro G62 and G72 Tricon System and Termination Enclosures

The G62 and G72 Tricon System and Termination Enclosures provide

environmental protection and housing, with termination and marshalling

options for Triconex™ Tricon system chassis and modules and DIN rail

mounted Triconex termination devices, such as External Termination

Panels (ETPs), Field Terminations and External Termination Assemblies (ETAs).

FEATURES

The G62 and G72 Tricon system and termination enclosures offer the

following features:

• Available sizes:

• G62 enclosure - 800x800x2000mm 

• G72 enclosure - 800x800x2200mm

• (Enclosure front) Vented enclosure

accommodates up to two Triconex™ Tricon system chassis

• (Enclosure rear) Two 1800 mm (or 2000 mm)

vertical DIN rails for mounting of Triconex termination devices to provide a total

of 3.6 m (or 4.0 m) of linear rail space. Optionally, one rail may be used to mount

terminal blocks for marshalling.

• Main power entry includes disconnect terminal blocks for 120/240 V ac or 125 V

dc systems, or 10 A, Type D, double pole circuit breakers for 120/240 Vac systems.

• Optional EMC/RFI line filters for redundant main power (Triconex recommended).

• Optional redundant 24 V dc field power - 480W (two field I/O power supplies) or

960W (four field I/O power supplies) with dedicated terminal block assemblies

providing independent disconnections for every Triconex termination device

• Vented enclosure for use in ordinary (IP 43) rated environments

• Option for EMC compliance

• Enclosure front and rear access, with optional safety glass front door

• Optional door intrusion monitoring switches

Alarm contact terminal block assembly for main chassis alarming, door intrusion

monitoring switches, enclosure temperature switch and field power supply status

• Compact design to minimize use of floor space with both front and rear access

that allow maximum density of enclosures in a control environment

• Available PVC or non-PVC wireways for field I/O cabling

• Generous 76 mm x 102 mm (3 in x 4 in) wire ducts with adequate capacity for

most wire management

• Bottom cable entry for field wiring

• Conveniently placed eyebolts for transporting and lifting the enclosures

• A 100 mm (4 in) plinth - total enclosure height of 2160 mm (85.0 in)

• Comfort handles with push-button/keylocks

• Three earth (ground) points; two protective earth (ground) studs, one isolated

protective earth (ground) rail and one isolated instrument earth (ground) rail

INTRODUCTION

The G62 and G72 enclosures are specifically designed for housing Tricon system

chassis and modules, DIN rail mounted Triconex termination devices and customer

-supplied terminal blocks for marshalling. These enclosures are available as vented

enclosures. They can be configured with:

• Up to two Tricon system chassis

• Two vertical DIN rails for mounting of Triconex termination devices. One rail may

be used to mount terminal blocks for marshalling.

The G62 and G72 enclosures are free-standing, floor mounted units with an IP 43

rating for location in mild (ordinary) environmental areas. Versions are available

with optional EMC compliance.

NOTE

In regions that require EMC compliance, you must order the EMC compliance option

if Tricon modules SMM or SRXM will be installed in a chassis in this enclosure.

Without these modules, these enclosures already fulfill the requirements for EMC

compliance.
