All of the following signals are energy-limited for the TB8-xx-xx-xx-03 transmitter
only. For the TB8-xx-xx-xx-04 Transmitter they are not energy-limited.
Note: These signals are not present on every model. Some models may have one-
piece screw terminal blocks and others may have two-piece pluggable terminal
blocks with either screw or spring clip terminals. These terminals will accept 0.325
to 1.31 mm
2
(22-16 AWG) conductor sizes. Conductor size 0.52 mm
2
(20AWG) or
larger cross section is recommended.
