• * Ensure the insulation space is suffi cient with a maximum length of 3mm for the lead wires coming
from the PCB. If an insuffi cient space allows the lead wires to touch a conductive surface, a possibility
of short-circuiting may occur.
• Use an 8mm diameter washer. If a washer with a diameter over 8mm is used, contact with the PCB
pattern may cause short-circuiting.
• Use all 4 mounting holes when installing and use the recommended torque to prevent the screws from
loosening and the product from unattaching.
