SAFETY INSTRUCTIONS

Do not dispose electronic equipment as unsorted municipal waste. Please use a separate collection facility or contact the supplier from which this instrument was purchased.

Safety Guidelines

General

Guideline

CAUTION

Do not place any heavy object on the instrument.

Avoid severe impact or rough handling that leads to damaging the instrument.

Do not discharge static electricity to the instrument.

Use only mating connectors, not bare wires, for the terminals.

Do not block the cooling fan opening.

Do not disassemble the GPT-9600 unless you are qualified.

(Measurement categories) EN 61010-1:2010 specifies the measurement categories and their requirements as follows. The GPT-9600 does not fall under category II, III or IV.

Measurement category IV is for measurement performed at the source of low-voltage installation.

Measurement category III is for measurement performed in the building installation.

Measurement category II is for measurement performed on the circuits directly connected to the low voltage installation.

Power Supply

WARNING

AC Input voltage range: 100-120/220-240VAC ±10%

Frequency: 50Hz/60Hz

Fuse: T 4A 250V

To avoid electrical shock connect the protective grounding conductor of the AC power cord to an earth ground.

Cleaning the

GPT-9600

Disconnect the power cord before cleaning.

Use a soft cloth dampened in a solution of mild detergent and water. Do not spray any liquid.

Do not use chemicals containing harsh material

		such as benzene, toluene, xylene, and acetone.
Operation		Location: Indoor, no direct sunlight, dust free,
Environment		almost non-conductive pollution (Note below)
	Relative Humidity: ≤ 70% (no condensation)
		Altitude: < 2000m
		Temperature: 0˚C~40˚C
	(Pollution Degree) EN 61010-1:2010 specifies the pollution degrees
	and their requirements as follows. The GPT-9600 falls under degree
	2.
	Pollution refers to “addition of foreign matter, solid, liquid, or
	gaseous (ionized gases), that may produce a reduction of dielectric
	strength or surface resistivity”.
	Pollution degree 1: No pollution or only dry, non-conductive
		pollution occurs. The pollution has no influence.
	Pollution degree 2: Normally only non-conductive pollution
		occurs. Occasionally, however, a temporary conductivity caused
		by condensation must be expected.
	Pollution degree 3: Conductive pollution occurs, or dry, non-
		conductive pollution occurs which becomes conductive due to
		condensation which is expected. In such conditions, equipment
		is normally protected against exposure to direct sunlight,
		precipitation, and full wind pressure, but neither temperature
		nor humidity is controlled.
Storage		Location: Indoor
environment		Temperature: -10°C to 70°C
	Relative Humidity: ≤ 85% (no condensation)
Disposal	Do not dispose this instrument as unsorted
	municipal waste. Please use a separate collection
	facility or contact the supplier from which this
	instrument was purchased. Please make sure

discarded electrical waste is properly recycled to reduce environmental impact.

SAFETY INSTRUCTIONS

Power cord for the United Kingdom

When using the safety tester in the United Kingdom, make sure the power cord meets the following safety instructions.

NOTE: This lead/appliance must only be wired by competent persons

WARNING: THIS APPLIANCE MUST BE EARTHED

IMPORTANT: The wires in this lead are coloured in accordance with the following code:

Green/ Yellow: Blue:

Brown:

As the colours of the wires in main leads may not correspond with the coloured marking identified in your plug/appliance, proceed as follows:

The wire which is coloured Green & Yellow must be connected to the Earth terminal marked with either the letter E, the earth symbol or coloured Green/Green & Yellow.

The wire which is coloured Blue must be connected to the terminal which is marked with the letter N or coloured Blue or Black.

The wire which is coloured Brown must be connected to the terminal marked with the letter L or P or coloured Brown or Red.

If in doubt, consult the instructions provided with the equipment or contact the supplier.

This cable/appliance should be protected by a suitably rated and approved HBC mains fuse: refer to the rating information on the equipment and/or user instructions for details. As a guide, a cable of 0.75mm2 should be protected by a 3A or 5A fuse. Larger conductors would normally require 13A types, depending on the connection method used.

Any exposed wiring from a cable, plug or connection that is engaged in a live socket is extremely hazardous. If a cable or plug is deemed hazardous, turn off the mains power and remove the cable, any fuses and fuse assemblies. All hazardous wiring must be immediately destroyed and replaced in accordance to the above standard.

	Workplace Precautions
	Background	The GPT-9600 Series are a high voltage
		instruments that output dangerous voltages.
		The following section describes precautions and
		procedures that must be followed to ensure a
		safe work environment.
	WARNING	The GPT-96XX generates voltages in excess of
		5kVAC or 6kVDC. Follow all safety precautions,
		warnings and directions given in the following
		section when using the instrument.
1.		Only technically qualified personnel should be
		allowed to operate the safety tester.
2.		The operating workplace must be fully isolated,
		especially when the instrument is in operation.
		The instrument should be clearly labeled with
		appropriate warning signage.
3.		The operator should not wear any conductive
		materials, jewelry, badges, or other items, such
		wrist watches.
4.		The operator should wear insulation gloves for
		high voltage protection.
5.		Ensure the earth ground of the line voltage is
		properly grounded.
6.		Ensure any devices that are adversely affected
		by magnetic fields are not placed near the
		tester.

Operating Precautions
Background	The GPT-9600 Series are high voltage
	instruments that output dangerous voltages.
	The following section describes precautions and

procedures that must be followed to ensure that the testers are operated in a safe manner.

The GPT-96XX generates voltages of up to 5kVAC

WARNING	or 6kVDC. Follow all safety precautions, warnings
	and directions given in the following section when
	using the instrument.
1.	Never touch the safety tester, lead wires,
	terminals, probes and other connected
	equipment when the tester is testing.
2.	Do not turn the safety tester on and off quickly
	or repeatedly. When turning the power off,
	please allow a few moments before turning the
	power back on. This will allow the protection
	circuits to properly initialize.
	Do not turn the power off when a test is
	running, unless in an emergency.
3.	Only use those test leads supplied with the
	instrument. Leads with inappropriate gauges
	can be dangerous to both the operator and the
	instrument.
4.	Do not short the HIGH VOLTAGE terminal
	with ground. Doing so could charge the chassis
	to dangerously high voltages.
5.	Ensure the earth ground of the line voltage is
	properly grounded.
	21

GPT-9600 Series User Manual

6.Only connect the test leads to the HIGH VOLTAGE terminals before the start of a test. Keep the test leads disconnected at all other times.

7.Always press the STOP button when pausing testing.

8.Do not leave the safety tester unattended. Always turn the power off when leaving the testing area.

9.When remotely controlling the safety tester, ensure adequate safety measures are in place to prevent:

Inadvertent output of the test voltage.

Accidental contact with the instrument during testing. Ensure that the instrument and DUT are fully isolated when the instrument is remotely controlled.

10.Ensure an adequate discharge time for the DUT.

When DCW or IR tests are performed, the DUT, test leads and probes become highly charged. The GPT-96XX has discharge circuitry to discharge the DUT after each test. The time required for a DUT to discharge depends on the DUT and test voltage.

Never disconnect the safety tester before a discharge is completed.

22

	GETTING STARTED
Basic Safety Checks
Background	The GPT-9600 Series are high voltage devices

and as such, daily safety checks should be made to ensure safe operation.

1. Ensure all test leads are not broken and are free from defects such as cracks or splitting.

2. Ensure the safety tester is always connected to an earth ground.

3. Test the safety tester operation with a low voltage/current output:

Ensure the safety tester generates a FAIL judgment when the HIGH VOLTAGE and RETURN terminals are shorted (using the lowest voltage/current as the testing parameters).

Do not use high voltages/currents when the HIGH

WARNING	VOLTAGE and RETURN terminals are shorted. It
	may result in damage to the instrument.
