Assembly
The 1734-TB, 1734-TBS, 1734-TB3, or 1734-TB3S wiring base assembly
consists of a 1734-MB mounting base and a 1734-RTB or 1734-RTBS
removable terminal block.
An alternative is the 1734-TOP, 1734-TOPS, 1734-TOP3, or 1734-TOP3S
POINT I/O one-piece terminal base.
Refer to the figures that show these wiring bases.
ATTENTION
POINT I/O is grounded through the DIN rail to chassis ground.
Use zinc-plated, yellow-chromated steel DIN rail to assure proper
grounding. The use of DIN rail materials (for example, aluminum
or plastic) that can corrode, oxidize, or are poor conductors, can
result in improper or intermittent grounding.
Secure DIN rail to mounting surface approximately every 200 mm
(7.8 in.).
