2. Terminal connecting method
Maximum output current of each output terminal is 25A except for LS25 (15A).
If more than 25A, use 2 terminals.
LOAD
( 25A max./ terminal)
( 25A max./ terminal)
Input must be off when making connection.
Connect FG terminal to ground terminal of the equipment.
The output load line and input line shall be separated and twisted to improve noise immunity.
