The display doesn’t
work as expected (no
display or showing
“888”) and the
operation of the unit
may be affected
Loose contact or pin-out problems in the RJ12
detachable display panel cable
A short (7”) RJ12 cable is used when the
detachable display panel is mounted on the unit
(factory default). Alternatively a long RJ12 cable
is provided for installing the display panel up to
7.5m away. Swap the cable you are using with the
other one and check display for correct operation.
Check the pin-to-pin conductivity of the cable
and the corresponding pin-out as shown in
“Appendix II”
Excessive EMI/RFI interference (electromagnetic
induction or electromagnetic radiation) emitted
from an external source
Avoid running the remote cable very close to
motors, power contactors/relays, ballasts,
transformers, or high voltage devices. In high
EMI/RFI environments, consider using metal
conduits or a shielded cable grounded at one end
and/or reduce cable length
The RCD trips as soon as
the load is connected
to either outlet port
There is a Neutral to Ground (M.E.N) bonding on
the AC load side of the IEC output socket
Locate and remove the Neutral to GND (M.E.N)
bonding on the load side. If the output of the
inverter is connected to an existing distribution
panel/box, make sure the Neutral and GND
connections inside the panel/box use separate
bus bars, being the Neutral one isolated from the
chassis ground. Otherwise consider using the 10A
AC-Output socket on the front of the unit.
