INTRODUCTION

The G60 enclosure is specifically designed for

housing Tricon system chassis and modules. It is

designed for use with the G61 or G66 Tricon

Termination Enclosures, and is available as a vented

enclosure only.

The G60 enclosure can be configured with up to

three Tricon chassis. Main power entry can include

optional EMC/RFI line filters. It is a free-standing,

floor mounted unit with an IP 43 rating for location in

mild (ordinary) environmental areas. A version is

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, the enclosure

already fulfills the requirements for EMC

compliance.

The G60 enclosure, IP 43 rated, can be installed

bayed or adjoined to others to maximize the use of

floor space and ease of cabling. The enclosures can

be bayed together using third-party kits.

This enclosure and its configurations have been

tested and qualified by Invensys for use with the

Tricon chassis.

NOTE

It is possible to configure the G60 enclosure

with front access only and the safety glass

front door. However, since no ventilation is

located on a rear wall, the end-user is

responsible for locating adequate inlet

ventilation to maintain proper operation of

the enclosure’s equipment, through

ventilation on a side wall or from an adjoined

cabinet.

Vented enclosures have a limited thermal load (see

“Operating Temperatures (Ambient)” on page 8).

INGRESS PROTECTION

The metal enclosures provide the outer layer of

protection for the control electronics. Other layers are

provided by the module covers and built into the

modules. This approach to protection means that a

minimum of contaminants in the plant environment

reaches the control components, thus greatly

extending the life of the equipment.

DUAL THERMOSTAT

An optional dual (high/low) thermostat is available to

monitor enclosure temperature extremes.

DOOR INTRUSION MONITORING

An optional door intrusion monitoring switch is

available for each door on the enclosure. Each switch

is prewired to a set of alarm status terminal blocks.
