Remove A Mounting Base; Wire The Module - Allen-Bradley D Series Installation Instructions Manual

POINT I/O Input Modules Installation Instructions
WARNING: For 1734-RTBS and 1734-RTB3S, to latch and unlatch the wire, insert a bladed screwdriver (catalog number 1492-N90 – 3 mm diameter blade) into
the opening at approximately 73° (blade surface is parallel with top surface of the opening) and push up gently.

Remove a Mounting Base

To remove a mounting base, you must remove any installed module, and the module that is installed in the base to the right. Remove the Removable Terminal Block, if wired.
WARNING: When you insert or remove the module while backplane 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. Repeated electrical arcing causes excessive wear to contacts on both the
module and its mating connector. Worn contacts may create electrical resistance that can affect module operation.
WARNING: When you connect or disconnect the Removable Terminal Block (RTB) with field-side power applied, an electrical arc can occur. This can cause an
explosion in hazardous location installations.
Be sure that power is removed or the area is nonhazardous before proceeding.
1. Unlatch the RTB handle on the I/O module.
2. Pull on the RTB handle to remove the removable terminal block.
3. Press the module lock on the top of the module.
4. Pull on the I/O module to remove from the base.
5. Repeat steps 1, 2, 3 and 4 for the module to the right.
6. Use a small bladed screwdriver to rotate the orange, base locking screw to a vertical position.
This releases the locking mechanism.
7. Lift straight up to remove.

Wire the Module

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.
WARNING: To comply with the CE Low Voltage Directive (LVD), this equipment must be powered from a source compliant with the following:
Safety Extra Low Voltage (SELV) or Protected Extra Low Voltage (PELV).
