WARNING: If you connect or disconnect wiring while the field-side power is on,
an electrical arc can occur. This could cause an explosion in hazardous location
installations. Be sure that power is removed or the area is nonhazardous before
proceeding.

isolation voltage.
ATTENTION: When using the 1756-TBCH, do not wire more than two
