• Make sure an adequate earth ground connection has been made be-
tween the grounding screw on the back of the controller and an
appropriate grounding point in your site.
• Adequate earth ground connection is mandatory to avoid any damage
or injuries.
• Wear an ESD wrist strap, ensuring that it makes good contact with bare
skin.
• Attach the ESD wrist strap end to an earth ground (grounding screw
on the back of the controller or unpainted bare metal spot of a grounded
equipment rack).
• Turn off the power switch of the controller.
• Turn off the power sources used to power the controller at the circuit
