DANGER
•
Before installing or removing the GOT main unit to or from an enclosure, always
switch off the GOT power externally in all phases.
Not doing so can cause a module failure or malfunction.
•
Before loading or unloading the communication board, communication module or
memory board to or from the GOT, always switch off the GOT power externally in all
phases.
Not doing so can cause a module failure or malfunction.
•
Before starting wiring, always switch off the GOT power externally in all phases.
Not doing so may cause an electric shock, product damage or malfunction.
CAUTION
•
The GOT should be used in the environment given in the general specifications of
this user's manual.
Not doing so can cause an electric shock, fire, malfunction or product damage or
deterioration.
•
When mounting the GOT main unit to an enclosure, tighten the mounting screws in
the specified torque range.
Undertightening can cause a drop, short circuit or malfunction.
Overtightening can cause a drop, short circuit or malfunction due to the damage of
the screws or module.
•
When loading the communication board or communication module to the GOT main
unit, fit it to the connection interface of the GOT and tighten the mounting screws in
the specified torque range.
Undertightening can cause a drop, failure or malfunction.
Overtightening can cause a drop, failure or malfunction due to the damage of the
screws or module.
•
When loading the memory board to the GOT main unit, do not touch the boards and
electronic parts directly.
Doing so can cause a module malfunction.
•
When loading the memory board into the GOT main unit, load it into its
corresponding GOT slot and tighten the mounting screws in the specified torque
range.
Undertightening can cause a malfunction due to a contact fault.
Overtightening can cause a malfunction due to the damage of the screws or
module.
•
Before loading or unloading the PC card to or from the GOT, set the memory card
access switch to the OFF position.
Not doing so can cause the PC card data to be corrupted.

Please make sure to ground FG terminal, LG terminal, and protective ground
terminal of the GOT power supply unit by applying Class D Grounding (Class 3
Grounding Method or higher) which is used exclusively for the GOT.
•
Correctly wire the power supply module on the GOT after confirming the rated
voltage and terminal arrangement of the product.
Not doing so can cause a fire or failure.
