NOTICE!
Damage from electrostatic discharge
All electronic equipment sensitive to damage from
electrostatic discharge, which can cause the con‐
trol unit to malfunction or fail.
– To protect electronic components from static
damage, take the precautions listed below.
1.
Avoid build-up of static electricity on your body by not
wearing clothing made of synthetic materials. Wear cotton or
cotton-blend materials as much as possible because these
do not store static electric charges as easily as synthetics.
2.
Before working on terminals on the control unit, ground your‐
self by touching and holding a grounded metal object (pipes,
cabinets, equipment, etc.) to discharge any static electricity.
Alternatively wear an ESD wrist band connected to ground.
3.
Before any maintenance work on the control unit, ground
yourself by touching and holding a grounded metal object
(pipes, cabinets, equipment, etc.) to discharge any static
electricity.
Alternatively wear an ESD wrist band connected to ground.
4.
Keep plastic, vinyl, and Styrofoam materials (such as plastic
or Styrofoam cups, cigarette packages, cellophane wrappers,
vinyl books or folders, plastic bottles, etc.) away from the
control unit, modules and work area.
5.
Opening the control cover may void the unit warranty. Do not
remove the printed circuit board (PCB) from the control cab‐
inet unless instructed by this manual.
If instructed by this manual to remove the
PCB from the control cabinet, follow these
precautions:
–
Ensure that the device is completely
voltage-free (all connectors have to be
disconnected).
–
Do not touch any part of the PCB except
the edges.
–
Do not touch the electrical conductors,
connectors, or components with conduc‐
tive devices or with bare hands.
–
When replacing a PCB, keep the new
PCB in the plastic antistatic protective
bag it comes in until you are ready to
install it. Immediately after removing the
old PCB from the control cabinet, place it
in the antistatic protective bag.
