Section 2 - Safety; Grounding; Terminals And Wiring - Vitrek 4700 Operating And Maintenance Manual

4700 Operating Manual - May 28, 2015
SECTION 2 – SAFETY
The user must be aware of these safety warnings at all times while using the 4700.
WARNING - THE 4700 MEASURES VOLTAGES WHICH MAY BE LETHAL; UNSAFE OPERATION MAY RESULT
IN SEVERE INJURY OR DEATH.
WARNING - IF THE 4700 IS USED IN A MANNER NOT SPECIFIED BY VITREK, THE PROTECTION PROVIDED
BY THE EQUIPMENT MAY BE IMPAIRED AND SAFETY MAY BE COMPROMISED.

GROUNDING

WARNING - THE USER MUST SECURELY GROUND THE PROTECTIVE GROUND TERMINAL LOCATED ON
THE 4700 REAR PANEL WHEN IN USE OR WHENEVER HIGH VOLTAGES MAY BE PRESENT.
NEVER – ATTEMPT TO USE THE 4700 WITHOUT THE PROTECTIVE GROUND TERMINAL BEING
GROUNDED IN AN ATTEMPT TO INCREASE THE COMMON MODE VOLTAGE CAPABILITY OF THE 4700.
THIS IS EXTREMELY DANGEROUS AND CAN DAMAGE THE 4700.

TERMINALS AND WIRING

WARNING - THE 4700 MEASURES VOLTAGES OF UP TO 10kVrms ON THE DIRECT TERMINAL, AND
VOLTAGES UP TO 140KVrms ON A PROBE TIP TERMINAL, THESE VOLTAGES CAN CAUSE SEVERE INJURIES
OR DEATH. THE USER MUST ENSURE THAT CONNECTIONS TO THESE HAVE SUFFICIENT INSULATION FOR
THESE VOLTAGES. EVEN WHEN SUFFICIENT INSULATION IS PRESENT, THE USER SHOULD NOT PUT ANY
PART OF THEIR BODY IN PROXIMITY TO THE CONNECTIONS WHILE HIGH VOLTAGES ARE PRESENT (AT
LEAST ½ INCH PER KV IS RECOMMENDED). THE USER SHOULD NOT INSERT OR REMOVE ANY
CONNECTIONS TO THE 4700 WHEN HIGH VOLTAGES ARE PRESENT.
WARNING – DO NOT APPLY HIGH VOLTAGES TO A PROBE WITHOUT IT BEING PROPERLY PLUGGED INTO
A 4700.
WARNING - WHEN USING AN EXTERNAL PROBE OR PROBES WITH THE 4700, NO PART OF THE USERS'
BODY MUST BE WITHIN 4" (HVP-35 OR HVL-35), 8" (HVL-70) OR 12" (HVL-100) OF THE PROBE BODY
(OTHER THAN THE HANDLE OF THE HVP SERIES PROBES) WHEN VOLTAGES MAY BE PRESENT.
WARNING – WHEN AC VOLTAGES ARE PRESENT, EVEN IF THERE IS SUFFICIENT INSULATION ON THE
CONNECTIONS, THERE MAY BE SIGNIFICANT CAPACITIVE COUPLING WHICH CAN CAUSE AN UNSAFE
CURRENT TO FLOW INTO NEARBY OBJECTS AND ALSO CORONA MAY OCCUR EVEN OUTSIDE OF THE
INSULATION. THESE EFFECTS ARE MADE WORSE BY SHARP CORNERS. IN SEVERE CASES CORONA CAN
CAUSE INTERFERENCE WITH THE MEASUREMENTS OF THE 4700 AND WILL REDUCE THE CAPABILITIES OF
THE WIRING INSULATION OVER TIME, EVENTUALLY RESULTING IN INSULATION FAILURE.
