Safety Precautions
The main circuit power will have dangerous voltage when it gets power
supply.
The input terminals (1L1, 3L2, 5L3) can not be connected with output
terminals (2T1, 4T2, 6T3).
The soft starter ’s output terminals (2T1, 4T2, 6T3) can not be connected
with compensation capacitor or sensitive resistance.
When soft starter and frequency inverter are standby mutually, the output
end has to be isolated from each other.
Do not attempt to repair the damaged device, please contact supplier
directly.
The temperature of the heat sink may be higher.
Do not supply reverse power on the output end of soft starter.
The high voltage always exists on the output side when starting or
stopping soft starter.
