NOTES
1. MOUNTING HOLES FOR RACK 19". USE M6x12 SCREWS TO FIX THE
UNIT TO A RACK.
2. USE NUT,FLAT WASHER AND SPRING WASHER FOR LOAD WIRES
FIXING. USE LUG STUD M6 FOR LOAD WIRES.RECOMMENDED
TORQUE: 42-56 Kgf.cm
3. TO FIX THE MOUNTING BRACKET TO THE CHASSIS USE M5x10 SEMS
SCREWS .RECOMMENDED TIGHTENING TORQUE 27~31Kgf.cm.
SCREWS MUST NOT PENETRATE THE CHASSIS MORE THAN 6.0 mm.
