 Anti-seize compound (when replacing GPT/MVT)
Note: When you service a ControlWave GFC Plus on site, we
recommend that you close down (or place under manual control)
any associated processes. This precaution prevents any processes
from accidentally running out of control when you conduct tests.
Caution
Harmful electrical potentials may still exist at the field wiring terminals
even though the ControlWave GFC Plus power source may be turned
off or disconnected. Do not attempt to unplug termination connectors
or perform any wiring operations until you verify that all associated
power supply sources are turned off and/or disconnected.
Always turn off any external supply sources for externally powered I.O
circuits before you change any modules.
WARNING
EXPLOSION HAZARD
Substitution of components may impair suitability for use in Class I,

installing or removing I/O wiring.
Do not disconnect equipment unless the power is switched off or the
area is known to be non-hazardous.
See Appendix A for details on Class I Division 2 usage of this device.
