2. Connect +V DC power to terminal 34 on the 34…51 row (C).
3. Connect -V to terminal 35 on the 34…51 row (C).
4. If continuing power to the next terminal base unit, connect a jumper
from terminal 50 (+V) on this base unit to terminal 34 on the next
base unit.
5. If continuing common to the next terminal base unit, connect a
jumper from terminal 51 (-V) on this base unit to terminal 35 on the
next base unit.
WARNING
Make certain that you power these modules with an intrinsically safe power
supply. Do not exceed the values listed in the specifications for these modules.
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.
ATTENTION
To reduce susceptibility to noise, power analog modules and digital modules
from separate power supplies.

ATTENTION Do not use the unused terminals on this terminal base unit. Using these
terminals as supporting terminals can result in damage to the module, or
unintended operation of your system, or both.
