SECTION 6 - MAINTENANCE

INTRODUCTION

The Serial Port Module (SPM) requires limited maintenance.
This section contains a maintenance schedule for the SPM and
other INFI 90 assemblies.

MAINTENANCE SCHEDULE

Perform the tasks in Table

6-1

at the specified intervals.

Table 6-1. Maintenance Schedule

Task

Interval

Clean and tighten all power and
grounding connections

Every 6 months or during plant shut-
down, whichever occurs first.

Use a static safe vacuum cleaner to
remove dust from:

Modules
Module Mounting Unit
