5.3.8 Connecting USB Cable Clamp

This clamp is used to prevent the USB cable connected to the USB Interface of the PL unit from being

unplugged due to vibration or other causes.

 Attaching the USB Cable Clamp

(1) Place the PL unit face-down on a flat surface as shown below. Your PL unit has four USB connectors.

(2) Fix the USB holder with two screws. The torque should be 0.5 to 0.6 N•m.

(3) As the figure shows, pass the USB Cable Clamp’s band around the depressed surface of the holder, twist

the USB Cable Clamp’s band around the USB cable, pull the band in the direction of the arrow, and then

fasten the band using the clamp.

• When using two or more USB ports, be sure to first connect one USB cable to the lower

USB connector, and then connect the second USB cable to the upper USB connector.

• When using only one of the USB ports, be sure to use the lower USB connector. This

allows you to securely clamp the USB cable in the cable clamp.

• Be sure the clamp is securely holding the USB cable’s plug and collar.

• Be sure the clamp is positioned as shown below, with the clamp pointing upwards - not to

the side.This is to keep the clamp from interfering with nearby connectors and their

cables.
