Safety Notices and Warnings (Cont)
WARNING:
HAZARDOUS VOLTAGES EXIST INSIDE THE GENERATOR WHENEVER THE MAIN
POWER DISCONNECT IS SWITCHED ON. THESE AREAS INCLUDE, BUT ARE NOT
LIMITED TO, THE MAIN FUSE HOLDER AND ASSOCIATED CIRCUITS ON THE H.V.
AUXILIARY BOARD, THE AUXILIARY TRANSFORMER, AND THE MAIN POWER
CONTACTOR.
LED DS1 ON THE H.V. AUXILIARY BOARD INDICATES THE PRESENCE OF THE
+24 VDC SUPPLY.
THE CONSOLE ON/OFF SWITCH DOES NOT DISCONNECT THE MAIN POWER
FROM THE ABOVE AREAS INSIDE THE GENERATOR.
THE DC BUS CAPACITORS, LOCATED IN THE MAIN CABINET PRESENT A
SAFETY HAZARD FOR AT LEAST 5 MINUTES AFTER THE POWER HAS BEEN
REMOVED FROM THE UNIT. CHECK THAT THESE CAPACITORS ARE
DISCHARGED BEFORE SERVICING THE GENERATOR.
AN LED CONNECTED ACROSS THE DC BUS INDICATES THE PRESENCE OF HIGH
VOLTAGE. THIS LED IS MOUNTED ON THE EMC CAPACITOR BOARD (ON SOME
MODELS, THE EMC CAPACITOR BOARD DOES NOT CONTAIN ANY
COMPONENTS OTHER THAN THE LED AND THE SERIES RESISTORS).
DO NOT RELY SOLELY ON BLEEDER CIRCUITS AND HIGH-VOLTAGE ON
INDICATORS IN THE GENERATOR TO PROTECT YOU. DUE TO THE
POSSIBILITY OF COMPONENT FAILURE, IT MUST NEVER BE ASSUMED
THAT AN UNLIT LED ENSURES THAT NO HIGH VOLTAGE IS PRESENT.
USING A VOLTMETER, CONFIRM THAT NO HIGH VOLTAGE IS PRESENT
BEFORE ATTEMPTING ANY SERVICE.
The following notes apply to the touchscreen console only.
WARNING:
THE TOUCHSCREEN CONSOLE HAS NO USER SERVICEABLE PARTS. DO NOT
ATTEMPT TO OPEN THE TOUCHSCREEN CONSOLE.
NOTE:
WHEN ATTACHING THE BASE TO THE TOUCHSCREEN CONSOLE, ENSURE THAT
THE TOUCHSCREEN IS RESTING ON A FLAT, CLEAN SURFACE WITH A PIECE OF
NON-ABRASIVE MATERIAL BETWEEN THE TOUCHSCREEN AND THE SURFACE.
NOTE: TO
AVOID
ACCIDENTAL
CONTACT WITH ENERGIZED CIRCUITRY INSIDE THE
TOUCHSCREEN CONSOLE, THE MAXIMUM BACK-PLATE SCREW LENGTH MUST BE
LIMITED TO 25 mm (1 INCH).
NOTE:
FOR WALL MOUNTED TOUCHSCREEN CONSOLES, ENSURE THAT THE BASE IS
SECURED PROPERLY TO A WALL STUD.
WARNING:
PLEASE ENSURE THERE IS SUFFICIENT AREA AROUND THE VENTING SLOTS
OF THE TOUCHSCREEN CONSOLE TO ALLOW PROPER COOLING OF THE
INTERNAL COMPONENTS.
