SECTION 6 - MAINTENANCE
INTRODUCTION
The Type STT03E terminal requires limited maintenance when operated
under normal conditions. Periodically the batteries require charging. Refer to
If the Type STT03E terminal is inoperative, or if operation is faulty, refer to
the troubleshooting section of this manual.
CLEANING
Before cleaning, turn the terminal off and disconnect it from the communica-
tion wires or loop. Make sure the battery charger is also disconnected. Wipe
the unit down using a soft cloth dampened with a nonabrasive, mild deter-
gent. Do so as often as the installation environment requires.
WARNING
System maintenance must be performed only by qualified personnel
and only after securing equipment controlled by the circuit. Altering
or removing components from an active circuit may upset the process
being controlled.
Explosionproof/dust-ignitionproof installations and intrinsically safe
installations in Class II or Class III hazardous locations require that
the assembly be kept tight while circuits are live unless the location is
known to be nonhazardous at the time.
AVERTISSEMENT
L'entretien du système ne doit être effectuquèe par le personnel quali-
fiè et seulement une fois que l'èquipement contrôlè par le circuit est
fixè en place. La modification ou le retrait des composants d'un circuit
actif pourraient perturber le processus controlè.
En ce qui concerne l'installation anti-explosion et anti-ignition provo-
què par la poussière dans des endroits se Classe II ou Class III, il est
indispensable que l'assemblage soit tenu ètanche pendant que les cir-
cuits sont èlectrises, a moins que cet endroit ne prsente aucun danger a
ce moment-la.
CAUTION
Do not allow cleaning solution or any other liquid to enter the terminal
case as it will damage internal components.
ATTENTION
Ne pas laisser une solution nettoyante ou un quelconque liquide
pènètrer le botier de raccordement, ceci pourrait endommager les
composants internes.
