7.2 Disconnect switch
When installing in a building, provide a suitable
disconnect switch for the supply voltage in order
to disconnect your system and thus your device
from the supply of power.
·Install the disconnect switch of your system or
device in such a way that it is easily accessible
by the user.
·Mark the switch as an isolation device for your
system or device.
·The isolation device must be UL/IEC approved.
INFORMATION
·As an alternative to the fuse and isolation de-
vice, you can use a line circuit breaker.
INFORMATION
·The voltage transformer ratios can be config-
ured via the GridVis
®

7.3 Supply voltage
WARNING
Risk of injury due to electrical voltage!
Severe bodily injury or death can result from:
·Touching bare or stripped leads that are ener-
gized.
·Device inputs that pose a hazard when touched.
·Disconnect your system from the power supply
before mounting and connecting the device!
·Secure it against being switched on!
·Check to be sure it is de-energized!
·Ground and short circuit!
·Cover or block off adjacent live parts!
A measured voltage and supply voltage are re-
quired to operate the device. The type and level of
the measured voltage and the supply voltage for
your device can be found on the rating plate.
Before applying the measured voltage and the
supply voltage, make sure that the voltage and
frequency match the specifications on the rating
plate.
·The device obtains its supply voltage from the
measured voltages L1-N, L2-N and L3-N. At least
one phase must be within the nominal voltage
range (see chapter „13. Technical data“ on page
54).
·The connection of the supply voltage via an
overcurrent protection device (UL/IEC approved)
is made via plug-in terminals on the bottom of the
device.
·A line circuit breaker can also be used as an iso-
lation device and a means of line protection. The
line circuit breaker must be UL/IEC approved.
·The overcurrent protection device must be adapt-
ed to the wire cross section used.
·After connecting the supply voltage, the green
LED on the front of the device lights up.
If the green LED does not light up, check:
·The connection of your device.
·The supply voltage.
CAUTION
Material damage due to disregard of the con-
nection instructions!
Disregard of the connection instructions can dam-
age or destroy your device.
Therefore please abide by the following:
·
Observe the voltage and frequency specifi-
cations on the rating plate!
·
Connect the measured voltage and supply
voltage via a fuse according to the technical
data!
·
Do not tap the measured voltage and supply
voltage at the voltage transformers!
·
Provide a fuse for the neutral conductor if
the neutral conductor terminal of the source
is not grounded!
