METREL A 1532 XA EVSE Adapter

1 Preface

Congratulations on purchasing and using the METREL A 1532 XA EVSE adapter accessory with METREL test and measuring instruments. The A 1532 XA is an extender for interfacing Electric Vehicle Supply Equipment (EVSE) to the test socket of an installation tester for verification of electrical safety and functional testing, including load testing. It is intended for testing Mode 3 EV supply equipment with a type 2 connector.

The A 1532 XA EVSE adapter is a special accessory intended to be used with METREL installation testers.

2 Safety and operational considerations

To maintain the highest level of operator safety while carrying out tests and measurements, METREL recommends keeping your EVSE adapter in good condition and undamaged. When using the adapter, consider the following general warnings:

• Warning on the A 1532 XA means "Read the Instruction manual with special care for safe operation". The symbol requires an action!
• If the A 1532 XA is used in a manner not specified in this Instruction manual or the Instruction manual of the target test equipment, the protection provided by the A 1532 XA and test equipment may be impaired!
• Read this Instruction manual carefully, otherwise use of the A 1532 XA may be dangerous for the operator, for test equipment, or for the tested object!
• Do not use the A 1532 XA if any damage is noticed!
• Mains test sockets and banana sockets are intended for test purposes only, as described in this manual!
• Service intervention is allowed to be carried out only by a competent authorized person!
• All normal safety precautions must be taken to avoid the risk of electric shock when working on electrical installations!
• Consider the maximal load current for intermittent and continuous operation!

2.2 Standards applied

The A 1532 XA adapter is manufactured and tested in accordance with the following regulations:

Safety (LVD)

• EN 61010-1: Safety requirements for electrical equipment for measurement, control and laboratory use – Part 1: General requirements
• EN 61010-2-030: Safety requirements for electrical equipment for measurement, control and laboratory use – Part 2-030: Particular requirements for testing and measuring circuits

Connections

Figure 4.2: A 1532 XA connection to EVSE – functional tests

Safety and functional tests:

• Connect the A 1532 XA output to the installation tester (via mains test socket or via safety banana sockets).
• Set PP STATE (3) to position N.C. and CP STATE (4) to position A.
• Connect A 1532 XA plug (6) to the EVSE.
• Run installation tests for non-energized installation circuits.
• Simulate different charging conditions with PP STATE (3) and CP STATE (4). Verify the response of the EVSE.
• In PP STATE (3) position different to N.C. and CP STATE (4) position in C or D, the EVSE output is energized (indicated by one or more (2) Voltage on EVSE indicators).
• Run installation tests for energized installation circuits.
• Run load test with maximum 13 A.
• Set CP STATE (4) to position A to de-energize EVSE, before disconnecting A 1532 XA plug (6) from EVSE.

Note:

• Only phase L1 of 3-phase EVSE is accessible through test socket (5).
• For the load test, mains socket or L1, L2, L3, N terminals can be used.

PP STATE options

CP STATE options

Recommended sequences:

• A-B-C for non-ventilated charging
• A-B-D for charging with ventilation required

Note: With A 1532 XA alone, only proximity pilot and control pilot functions of EVSE can be checked.

Fault simulation options

Recommended test procedure: While the EVSE is in state C or D, press and hold any of the fault simulation push buttons (8) for at least 3 s and check the response of the EVSE.

Checking CP signal

• Connect Oscilloscope to BNC connector (7) using 10:1 probe with 10 MΩ input resistance.
• Set PP STATE (3) position to proper EVSE current output selection.
• Set CP STATE (4) to position A.
• Set tested EVSE to operate.
• Set CP STATE (4) to position B and/or C and modify PP STATE (3) position to all applicable currents.
• Check waveforms and amplitudes of measured CP signal.

Notes:

• If the input resistance is 1 MΩ instead of recommended 10 MΩ, the measured signal amplitude is approx. 17 % lower than actual value.
• Oscilloscope probe shall be compensated to get proper frequency response.
• Portable / handheld battery powered oscilloscope is recommended for observing CP signal.

Warning: If 50 Hz / 60 Hz noise is visible in the signal, it is possible to suppress it by connecting the PE socket to oscilloscope ground. However, in this case, it must be assured before that there is no hazardous voltage on the PE conductor of the EVSE and use of safe accessories is recommended.

5 Maintenance
