Rotation eld direction
Check the direction of the voltage rotation eld on the measured
value display of the Energy Meter 610/610-PB.
Usually there is a “clockwise” spinning rotation eld.
Checking the phase assignment
The assignment of the phase conductor to the current transformer
is correct if a current transformer is short circuited at the secondary
terminals and the current shown by the Energy Meter 610/610-PB
in the corresponding phase sinks to 0 A.
Checking the power measurement
Short circuit all current transformer outputs except for one and
check the displayed power. The Energy Meter 610/610-PB must
only show one rating in the phase with the non-short-circuited cur-
rent transformer input. If this does not apply, check the measured
voltage connection and the measured current connection.
If the magnitude of the real power is correct but the sign of the real
power is negative, this can be due to two causes:
• The connections S1(k) and S2(I) on the current transformer are
inverted.
• Active energy is being returned to the network.
Checking the measurement
If all voltage and current measurement inputs are correctly con-
nected, the individual and sum power ratings are accurately calcu-
lated and displayed.

Applying the supply voltage
• The level of supply voltage for the Energy Meter 610/610-PB
can be found on the nameplate.
• After applying the supply voltage, the Energy
Meter 610/610-PB switches to the rst measured value display.
• If no display appears, the supply voltage must be checked to
determine whether it is in the rated voltage range.
Applying the measured voltage
• Voltage measurements in networks with rated voltages above
300 V AC to ground must be connected to a voltage trans-
former.
• After the measured voltages are connected, the measured
values for the L-N and L-L voltages displayed by the Energy
Meter 610/610-PB must match those at the voltage measure-
ment input.
Attention!
Voltages and currents outside the permissible meter-
ing range can result in personal injury and damage to
the device.
Applying the measured current
The Energy Meter 610/610-PB is designed for connecting ../1A
and ../5A current transformers.
Only AC currents and not DC currents can be measured via the
current measurement inputs.
Short circuit all current transformer outputs except for one. Com-
pare the currents displayed on the Energy Meter 610/610-PB with
the applied current.
The current displayed by the Energy Meter 610/610-PB must
match the input current, taking the current transformer ratio into
consideration.
In the short circuit current measurement inputs, the Energy
Meter 610/610-PB must show approx. zero amperes.
The factory-set current transformer ratio is 5/5A and may need to
be adapted to the current transformer used.
Attention!
Supply voltages that do not correspond to the name-
plate information can lead to device malfunction or
destruction.
Attention!
The Energy Meter 610/610-PB is not suitable for the
measurement of DC voltages.
