SECTION 7 - MAINTENANCE

System maintenance must be performed only by qualified per-
sonnel and only after securing equipment controlled by the cir-
cuit. Altering or removing components from an active circuit
may upset the process being controlled.
The STT04 terminal requires limited maintenance when operated
under normal conditions. Periodically the battery pack requires charg-
ing. Refer to Charging STT04 Terminal
If the STT04 terminal is inoperative, or if operation is faulty, refer to
the troubleshooting section of this manual.
Do not allow cleaning solution or any other liquid to enter the
terminal case as it will damage internal components.
Before cleaning, turn the terminal off and disconnect it from the com-
munication wires or loop. Make sure the battery charger is also dis-
connected. Wipe the unit down using a soft cloth dampened with a
nonabrasive, mild detergent. Do so as often as the installation envi-
ronment requires.
