WARNING
EXPLOSION HAZARD
Substitution of components may impair suitability for use in Class I,
Division 2 environments.
When the ControlWave GFC Plus is situated in a hazardous location,
turn off power before servicing or replacing the unit and before
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.
4.1 Powering Up/Powering Down the ControlWave GFC Plus
The ControlWave GFC Plus receives power either from a solar panel
and user-supplied battery or from an external bulk power supply
attached using connector TB1 on the CPU/System Controller board. It
can also receive power through alternate connector TB2 on the same
board. Chapter 2 includes instructions for wiring power to the
ControlWave GFC Plus. See Figure 2-3 for the location of these
connectors.
Power Up
To apply power to the ControlWave GFC Plus, plug in connectors TB1
and optionally TB2 on the CPU/System Controller board. If your
ControlWave project resides in flash memory, the project will load into
SRAM and begin execution. Depending upon the setting of the SRAM
control switch, retain variable values may load as well.
