1.2. During Power Up
1.3. Before Operation
Danger When the momentary power loss is longer than 2 seconds, the inverter will not have
sufcient stored power for its control circuit. Therefore, when the power is re-applied,
the run operation of the inverter will be based on the setup of following parameters:
• Run parameters. 00-02 or 00-03.
• Direct run on power up. Parameter. 07-04 and the status of external run switch,
Note:
The start operation will be regardless of the settings for parameters 07-00/07-01/07-02.
Danger. Direct run on power up.
If direct run on power up is enabled and inverter is set to external run with the run
FWD/REV switch closed then the inverter will restart
Danger
Prior to use, ensure that all risks and safety implications are considered.
• When the momentary power loss ride through is selected and the power loss is
short, the inverter will have sufficient stored power for its control circuits to
function, therefore,when the power is resumed the inverter will automatically
restart depending on the setup of parameters 07-00 & 07-01.
Caution Make sure the model and inverter capacity are the same as that set in parameter
13-00.
Note:
On power up the supply voltage set in parameter 01-01 will flash on display for 2
seconds.
