Install the Mounting Base

To install the mounting base on the DIN rail (Allen-Bradley® part number 199-DR1; 46277-3; EN50022), proceed as follows.

ATTENTION: This product is grounded through the DIN rail to chassis ground. Use zinc plated chromate-passivated steel DIN rail to assure proper grounding.
The use of other 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.) and use end-anchors appropriately. Be sure to ground the DIN rail properly. See Industrial Automation Wiring and Grounding Guidelines, Rockwell Automation publication 1770-4.1, for more information.

WARNING: When used in a Class I, Division 2, hazardous location, this equipment must be mounted in a suitable enclosure with proper wiring method that complies with the governing electrical codes.

Position the mounting base vertically above the installed units (adapter, power supply or existing module).
Slide the mounting base down allowing the interlocking side pieces to engage the adjacent module or adapter.
Press firmly to seat the mounting base on the DIN rail. The mounting base snaps into place.

Install the Module

The module can be installed before or after base installation. Make sure that the mounting base is correctly keyed before installing the module into the mounting base. In addition, make sure the mounting base locking screw is positioned horizontal referenced to the base.

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.

To install the module, proceed as follows.

Use a bladed screwdriver to rotate the key switch on the mounting base clockwise until the number required for the type of module you are installing aligns with the notch in the base.
Make certain the DIN rail locking screw is in the horizontal position. You cannot insert the module if the locking mechanism is unlocked.

6 Rockwell Automation Publication 1734-IN055J-EN-E – September 2022
Insert the module straight down into the mounting base and press to secure. The module locks into place.

Install the Removable Terminal Block

A Removable Terminal Block (RTB) is supplied with your wiring base assembly. To remove, pull up on the RTB handle. This allows the mounting base to be removed and replaced as necessary without removing any of the wiring. To reinsert the Removable Terminal Block, proceed as follows:

WARNING: When you connect or disconnect the Removable Terminal Block with field side power applied, 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

Insert the end opposite the handle into the base unit. This end has a curved section that engages with the wiring base.
Rotate the terminal block into the wiring base until it locks itself in place.
If an I/O module is installed, snap the RTB handle into place on the module.

WARNING: For 1734-RTBS and 1734-RTB3S, to latch and un-latch 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.

WARNING: For 1734-TOPS and 1734-TOP3S, to latch and un-latch the wire, insert a bladed screwdriver (catalog number 1492-N90 – 3 mm diameter) into the opening at approximately 97° (blade surface is parallel with top surface of the opening) and press in (do not push up or down).

Remove a Mounting Base

To remove a mounting base, you must remove any installed module, and the module 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.

Unlatch the RTB handle on the I/O module.
Pull on the RTB handle to remove the removable terminal block.
Press on the module lock on the top of the module.
Pull on the I/O module to remove from the base.
Repeat steps 1, 2, 3 and 4 for the module to the right.
Use a small bladed screwdriver to rotate the orange, base locking screw to a vertical position. This releases the locking mechanism.
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.

ATTENTION:

The power supply voltage may be daisy chained from a 1734 adapter, 1734-FPD or 1734-EP24DC communication interface. Each channel is individually isolated and may have a unique supply and/or voltage as necessary.
Do not attempt to increase load current or wattage capability beyond the maximum rating by connecting two or more outputs in parallel. The slightest variation in relay switching time may cause one relay to momentarily switch the total load current.
Make sure that all relay wiring is properly connected before applying any power to the module.
Total current draw through the wiring base unit is limited to 10 A. Separate power connections to the terminal base unit may be necessary.
Use the end cap from your adapter or interface module to cover the exposed interconnections on the last mounting base on the DIN rail. Failure to do so could result in equipment damage or injury from electric shock.

The module complies to Ex when used at or below 120V AC.
For maximum rating at voltages between the maximum design value and 120V, the maximum make and break ratings are to be obtained by dividing the volt-amperes rating by the application voltage. For voltages below 120V, the maximum make current is to be the same as for 120V, and the maximum break current is to be obtained by dividing the break volt-amperes by the application voltage, but these currents are not to exceed 2 A.
