Design Considerations for
Maintenance Activities
Maintenance Activities
The design of the installation must allow preventive and corrective
maintenance activities to take place. Corrective maintenance tasks will
embrace the identification and renewal of defective modules and other
assemblies and, when exhausted, renewal of the back-up battery within the
T9110 processor module.
Fuses on the termination assemblies can be replaced so access to the fuses is
required. There are no user-serviceable parts inside modules therefore repair is
by replacement; defective modules should be returned to Rockwell
Automation for investigation and repair.
WARNING: EXPLOSION HAZARD
Do not connect or disconnect equipment, while the circuit is live or unless the
area is known to be free of ignitable concentrations or equivalent.
AVERTISSEMENT: RISQUE D’EXPLOSION
Ne pas connecter ou déconnecter l’équipement alors qu’il est sous tension,
sauf si l’environnement est exempt de concentrations inflammables ou
équivalente.
