11. Commissioning
11.1 Supply voltage
Proceed as follows when applying the supply
voltage:
1. Connect the supply voltage to terminals 1 and
2 of the device. The proper supply voltage can
be found on the rating plate.
2. The standard display appears on the display.
3. If no display appears, check:
- The connection of your device.
- Whether the supply voltage is within the nom-
inal voltage range.
INFORMATION
Before commissioning, delete any production-relat-
ed contents of the energy meters (see section „10.3
Parameter list“ on page 52).
WARNING
Material damage due to disregard of the con-
nection instructions!
Voltages and currents outside the permissible
measuring range can destroy the device.
Comply with the measuring range specifica-
tions from the technical data.
11.2 Measured voltage
Connect measured voltage:
1. Connect the measured voltage to the terminals
provided for this purpose (see section "Instal-
lation").
2. After connecting the measured voltage, check
the measured values displayed by the meter for
the voltages L-N and L-L (take into account any
voltage transformer factors that may have been
set).
INFORMATION
·In networks that exceed the specified nominal
voltages, make sure to connect the voltage
measurement inputs via voltage transformers
WARNING
Risk of injury due to electrical voltage!
If the device is exposed to surge voltages above
the permissible overvoltage category, safety-rele-
vant areas of insulation in the device can be dam-
aged. This means that the safety of the product can
no longer be guaranteed.
Only use the device in environments in which
the permissible overvoltage category is not
exceeded (cf. section “Technical data”).
11.3 Frequency measurement
The device requires the mains frequency for the
measurement and calculation of measured values.
The mains frequency is determined automatically
by the device.
·To determine the mains frequency, a voltage
greater than 10 V
eff
(4-conductor measurement)
or a voltage L1-L2 greater than 18 V
eff
(3-con-
ductor measurement) must be applied to voltage
measurement input V1.
·The mains frequency must be in the range from
45 Hz to 65 Hz.
·If the measured voltage is not sufficiently high,
the device cannot determine the mains frequency
and therefore cannot carry out a measurement.
