Problem

Solution
No light for the
Power supply
indicator (L1, L2 &
L3 LED).
Is AC power supply
connected to the
meter ?
Is the L1, L2, L3 and
N connecting
correct ?
Are the terminals 1,
2, 3, 4, 5, 6 and 7
connecting correct ?
Maybe there is a
fault in the inside
circuit.
Check switch or circuit-breaker
and fuse or thermal cut-off.
Re-install terminal screws on the
L1, L2, L3 and N. Make sure all
screws are fixed. Than there
should be a 230V 50Hz AC voltage
between the terminal screws on
the N and L1 or L2 or L3, when
power supply is input.
Reinstall terminal screws on the
1, 2, 3, 4, 5, 6 and 7. Make sure
all screws are fixed. Than there
should be a 230V 50Hz AC voltage
between the terminal screws on
the 7 and 1 or 3 or 5, when power
supply is input.
Please contact your technical
supporter to replace this meter.
No light for the
consumption
indicator (PULSE
LED).
Is the load
running ?
Is the operating
power too low ?
Maybe there is a
fault in the inside
circuit.
Only when load is running, this
LED will flash.
If the operating power is too low,
the spacing interval of the flashes
will take some more time this is
why it seems like LED is not
burning
Please contact your technical
supporter to replace this meter.
