Replacement
Replacement parts may contain static-sensitive components. Therefore, GE ships replacement parts in anti-static bags. When
handling electronics, make sure to store them in anti-static bags or boxes and use a grounding strap (per the following Caution
criteria).
Caution
To prevent component damage caused by static electricity, treat all boards with
static-sensitive handling techniques. Wear a wrist grounding strap when handling
boards or components, but only after boards or components have been removed from
potentially energized equipment and are at a normally grounded workstation.
Warning
To prevent personal injury or damage to equipment, follow all GE safety procedures,
Lockout Tagout (LOTO), and site safety procedures as indicated by Employee Health
and Safety (EHS) guidelines.
Warning
This equipment contains a potential hazard of electric shock, burn, or death. Only
personnel who are adequately trained and thoroughly familiar with the equipment
and the instructions should install, operate, or maintain this equipment.
Troubleshooting should be done at the system component level. The failed system component (least replaceable part) should
be removed, returned to GE, and replaced with a known good spare. Do not attempt to repair system components.
Warning
To prevent electric shock, turn off power to the equipment, then test to verify that no
power exists in the board before touching it or any connected circuits.
Caution
To prevent equipment damage, do not remove, insert, or adjust board connections
while power is applied to the equipment.
Attention
Replacement of the terminal board requires full reconfiguration of the changed
component using the ToolboxST application. For this reason, it is generally preferable
to replace only the I/O pack unless the terminal board is known to be the point of
failure.
