3. Terminate shields to terminals 16 or 33 on row B, or 40 through
45 on row C.
4. Connect +24V dc to terminal 34 on the 34-51 row (C).
5. Connect dc return to terminal 16 on the 16–33 row (B).
!
ATTENTION: To reduce susceptibility to noise,
power frequency modules and digital modules from
separate power supplies. Do not exceed a length of 33
ft (10m) for dc power cabling.
6. If continuing power to the next terminal base unit, connect a
jumper from terminal 51 (+24V dc) on this base unit to terminal
34 on the next base unit.
7. If continuing common to the next terminal base unit, connect a
jumper from terminal 33 (common) on this base unit to terminal
16 on the next base unit.
!
ATTENTION: Do not daisy chain power or ground
from this terminal base unit to any ac or dc digital
module terminal base unit.
!
ATTENTION: This module does not receive power
from the backplane. +24V dc power must be applied to
your module before operation. If power is not applied,
the module position will appear to the adapter as an
empty slot in your chassis. If the adapter does not
recognize your module after installation is completed,
cycle power to the adapter.
