Safety Warnings

The following Safety Warnings and Precautions must be read and understood before the instrument is used. They must be observed during use.

■ Only use test leads and accessories supplied or approved by Megger Instruments Limited
■ At any time the Gsymbol or Fsymbol is displayed, the user guide and warnings documentation must be consulted to identify the nature of the hazard and any actions
necessary to avoid the hazard
■ Do not use the instrument if there are any signs of damage
■ This instrument meets the EMC requirements of Class A applications. Not for use in domestic installations
■ All test leads, probes and clips must be in good order, clean and with no broken or cracked insulation
■ Probes and clips should be held behind the finger guard
■ Test leads not used during a measurement should be disconnected from the Appliance tester
■ During testing, ensure no hazard will exist as a result of normal running or under fault conditions
■ During testing the unit under test (appliance) should not be touched, other than using the appropriate accessories, as faulty appliances can present a shock hazard
■ Do not touch the exposed parts of test leads during tests as hazardous voltages may be present
■ Do not intentionally connect test leads to live systems or hazardous voltages
■ Do not touch the IEC extension lead socket pins especially during a test, as hazardous voltages may be present due to a potentially faulty appliance
■ Do not touch the exposed earth pins of the 230 V test socket during a test, as voltages may be present due to a potentially faulty appliance
■ Serviceable fuses should only be replaced with those that are suitably rated
■ Replacement fuses must be of the correct rating and type. Refer to page 33
■ If this instrument is used in a manner not specified in the supplied documentation, the protection provided by the instrument may be compromised

PAT150
■ For safety, only connect the PAT to a supply that is properly earthed. If in doubt, the supply should be checked by a qualified electrician
■ Only perform a mains powered leakage test after the Earth bond and insulation tests have been completed, as this test operates at mains voltage
■ During mains powered leakage tests the appliance under test will operate. Make sure the appliance is safely secured to ensure no damage or danger is possible
■ A yearly calibration is recommended with interim checks on measurement accuracy to ensure no equipment can be left in a hazardous live condition through incorrect readings
■ Only use a Megger approved PAT100 charger. Other chargers may present a fire risk
■ Do not connect the battery charger to the PAT150R whilst running a test
■ During testing make sure that the shutter covers the battery charger port. There is a risk of electrocution from exposed terminals. Do not touch any exposed terminals or probe tips
during test
■ Always remove the mains plug test lead from the mains supply AND the instrument when not in use

Product Safety Category
CATII 300 V - MEASUREMENT CATEGORY II Equipment connected between the electrical outlets and the user’s equipment.
G230 V ac powered Leakage testing: Connecting the PAT150 to a 230 V ac supply will automatically switch the leakage tests from a 40 V ac test to a mains powered 230 V ac test. Any
leakage testing performed with 230 V ac connected will operate the equipment under test. Ensure the equipment under test is properly secured and in a safe condition prior to running a
230 V ac leakage test
