AEM33 V 485 DIN
INSTRUCTIONS
1 SAFETY
This instrument is manufactured in compliance with EN61010-1
Cat III for nominal operating voltages of 400V L-L and 230V L-N,
to ensure safe operation the user must comply with the
following instructions:
•
Ensure that the supply voltage is correct.
•
The auxiliary mains supply is internally fused at 250V,
100mA Type 2. External fusing is required if the auxiliary
supply voltage exceeds 250V.
•
Maintenance and/or repairs must be carried out only by
qualified, authorised personnel.
•
If there is ever the suspicion that safe use is no longer
possible, the instrument must be disconnected and
precautions must be taken against accidental use.
•
Operation is no longer safe:
1) If there is clearly visible damage
2) If the instrument no longer functions
3) After prolonged storage in unsuitable conditions.
1.1 OPERATOR SAFETY
Read these instructions carefully before installing and utilising
the instrument.
The instrument described in this user manual is intended for
use by properly trained staff only. Maintenance and/or repairs
must be carried out by authorised personnel only. For proper,

2 SYMBOLS
CAUTION: Failure to follow the instructions may result in
personal injury or damage to equipment.
NOTE: Failure to follow the instructions may result in
an instrument malfunction.
3 INSTALLATION
Current Sensor Installation
The following diagram shows how each device is fitted on the cable
for correct operation:
The secondary cables should be wired with the correct polarity.
The white cable (or black/white) is the negative and should be
connected to S2 or CT- on the meter. The black cable is the
positive and should be connected to S1 or CT+ on the meter.
NOTES:
•
The output from these current sensors is a low voltage. It
is safe to leave these outputs open-circuit if not connected
to a meter.
•
The output connections from these current sensors must
be individually wired direct to the meter and must not be
earthed or connected to any other circuit.
•
If the sensor secondary cables require extending the
following instructions apply:
Cables may be extended to a total distance of 25 metres
provided the following restrictions are observed.
Cable must be twisted pair, screened, min 22AWG.
Recommended type is Belden 8451 or equivalent.
Cables should be mounted away from AC power cabling.
Outside the main enclosure, separate containment or a
separation of >100mm is recommended.
NOTE: Above cable is rated at 300V. Additional
containment may be required if running inside panels with
exposed conductors.
•
Current sensor polarity is irrelevant in Auto CT Rotation
Mode.
