5. Troubleshooting
5.1Safety during Troubleshooting
High electric voltage! Risk of death or personal injury by electric shock!
Never work with live wires! It is prior to all connection and maintenance work.
Make sure that the AC and DC wires are not charged.
The connection area should only be opened by a licensed electrician.
Warning! Danger from residual voltage out of capacitors.
You must wait until the capacitors have fully discharged. Discharge takes around15
minutes.
Caution! Danger from inadequate grounding.
An inadequate grounding conductor connection can cause serious injuries to
persons and damage to properties.
5.2 Faults
A fault can be divided into two catalogues: a permanent failure and a temporary failure. A ‘permanent
failure’ is defined by a fault having been present for more than 15 minutes and cannot be
acknowledged by inverter’s auto-restart. Unlike permanent failure, a “transient failure" is
automatically acknowledged by the inverter. The inverter attempts to restart once the error no longer
exists. The fault is indicated on the control panel by the red "Alarm" LED emitting steady light. Most
failures are transient; therefore the system should be monitored for a while before contacting the
service as the transient failure may disappear itself.
5.3 Fault Messages and Actions List
Fault messages are stored in the fault memory even in the status of power failure. The fault data can
be retrieved to display on the screen. The latest 100 fault logs are recorded in the fault memory. The
latest fault is kept at memory location S0 while the earliest at S100.
The transient failure is shown as “Warning” while the permanent failure as “Fault”. Check ‘Warnings
and actions’ table when a transient failure occurs and check the ‘Faults and actions’ table when a
permanent failure occurs.
