Electrostatic Discharge
Before touching the device, or holding the boards and IC chips, wear the ESD gloves or the
ESD wrist strap to prevent the electrostatic discharge of the human body from damaging the
sensitive components. Ensure that the other end of the ESD wrist strap is properly grounded.
ESD gloves
Bundling cables
• The distance between cable ties or binding straps inside the cabinet must be within 250 mm.
(For user cable, the distance must be within 200 mm.)
• Use diagonal pliers to cut off the extra part of the cable tie to the end, and ensure that the
cable tie is neat without sharp edges to prevent hand injury.
Affixing labels / tags

connector.
• After the label for the signal cable is attached to the signal cable, the rectangular text area of
the label must face rightwards or downwards.

the plate must face rightwards or upwards. Ensure that the side attached with the label faces
