If you have any of the products listed below, please read and action the customer safety notices relating to your instrument.
Megger has identified a potential electrical safety hazard which, should a fault occur within the EVCA210 Electric Vehicle Charge-Point Adaptor, could compromise the electrical safety within the unit.
Safety is always Megger’s highest priority. Consequently, we have taken the decision that all EVCA210s must be returned for modification to install the additional mechanical protection.
The modification is necessary and Megger will endeavour to complete the work and return your unit as quickly as possible. Units shall be returned to Dover where we will undertake the corrective action free of charge.
We apologise for any inconvenience this action may cause and can assure you we will be working to expedite the modification and return your adapter to you as quickly as possible.

Through our programme of continuous improvement, we wish to draw your attention to loop impedance testing on very high earth resistances. This notice covers the MFT1700, 1800 and 1701 series multifunction testers from Megger Instruments Limited.
Measurement affected: 3-wire non-trip loop impedance test.
In the very unlikely situation that a 3-wire loop impedance test is applied to a circuit of between 3300 Ω to 100,000 Ω to earth, there is a possibility that the voltage appearing on the CPC could exceed 50V. Although this lasts for less than half a second, this may be momentarily experienced by someone touching exposed bonded metalwork during the test.
This condition will not arise if the earthing and bonding has been verified as acceptable prior to performing a 3-wire earth loop impedance test.
Our advice to customers.
We consider the likelihood of this situation arising to be extremely rare and Megger has no record of any occurrence of this condition in the lifetime of this product range.
Instruments will be automatically updated when returned for routine calibration or repair, or customers can call Megger Limited for a Returns Authorisation number and return their MFT as below:

If customers are concerned about this condition, performing an RCD test on the circuit prior to the loop impedance test will alert the operator to any high resistance condition. This only affects the 3-wire non-trip loop impedance test. All other tests including other loop impedance tests are unaffected.
