then perform the following steps to extract the module:

If the Alarm condition persists (the LED Indicator ALARM will

Maintenance Bypass (IA1) may be closed by turning it to position
“ON”.
NOTE: If the load is on inverter then before closing the Maintenance
Bypass IA1, transfer load to bypass by means of the

LCD: “LOAD NOT PROTECTED” will appear.
