Warning

• Socket output and banana socket outputs are energized when one or more indicators (2) lit.

A 1532 operation

Testing procedure

• Connect the A 1532 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 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.
• Set CP STATE (4) to position A to de-energize EVSE, before disconnecting A 1532 plug (6) from EVSE.

Note

• Only phase L1 of 3-phase EVSE is accessible through test socket (5).

PP STATE options

Coding for maximum current of the EV cable.

EVSE is connected and can operate in any of these coding position.

20 A
32 A
63 A

CP STATE options

EVSE does not supply energy
B| EV connected| EV detected, EV not ready to receive energy, EVSE does not supply energy
C| EV charged      without ventilation| EV ready to receive energy, EVSE is supplying energy if ventilation is not required.
D| EV      charged      with ventilation| EV ready to receive energy and requires ventilation, EVSE is supplying energy only if ventilation exists.
E| Pilot fail| EVSE doesn’t supply energy (no power).

The EV supply equipment unlocks the socket outlet at maximum of 30 s.

Recommended sequences

• A-B-C for non-ventilated charging
• A-B-D for charging with ventilation required
• E is required for simulating Pilot failure.

Note

• With A1532 alone only proximity pilot and control pilot functions of EVSE can be checked.

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.

Maintenance

Unauthorized person is not allowed to open the A 1532 EVSE adapter. There are no user replaceable components inside the adapter.

Cleaning

No special maintenance is required for the housing. To clean the surface of the adapter use a soft cloth slightly moistened with soapy water or alcohol. Then leave the A 1532 to dry totally before use.

Warnings

• Do not use liquids based on petrol or hydrocarbons!
• Do not spill cleaning liquid over the adapter!

Service

• For repairs under warranty, or at any other time, please contact your distributor.
