Connection to a Meter Testing Device

D000027979 en t – E350 Series 2, 3-Phase ZxF100Ax/Cx – User Manual
To test the meter, connect it to a dedicated testing device.
The meter uses a voltage jumper whereby a spring contact connects the
voltage circuit of the meter to the phase terminal. By inserting a contact pin
of 2.5 mm diameter, the voltage and current circuits of the meter are
separated and the test voltage is connected via the contact pin. See Fig.
7.1.

Procedure:
1. Connect the meter to the terminals of the testing device as shown in
the meter connection diagram and according to the usual testing
methods. Remove the access lock sliding piece, if present.
2. To connect the test voltage, use a connecting cable with a contact pin of
2.5 mm diameter and 40 mm length (± 1 mm). Insert this pin in the
opening provided on the front of the terminal block, right above the
measuring terminals.
Keep voltage cables free from voltage when inserting
Touching live contact pins can be fatal.
3. After testing, remove the cable (voltage-free!) from the terminal cover.
The spring closes the contact and the voltage is connected again.
Insert the access lock sliding piece again, if necessary, and seal it.
