128 -** Do not place signal cables near high voltage power cables or in the same trunk line. Otherwise, it may be disturbed or surged. Keep a safe distance between signal cable and power cable, at least 100mm.
129 -** Ground the shielding of shielded wire or shielded cable. But the ground point and high voltage line cannot be the same.
130 -** Do not connect cables of impermissible size to avoid poor contact or product damage.
131 -** Fix the cable so that no force directly acts on the terminal line or cable connection area.
132 -** The tightening torque of terminal is 0.5Nm to 0.6N.m. Please tighten it to prevent malfunction.
133 -** Do not use empty terminals.
