WAR N IN G :
• When you connect or disconnect the Removable Terminal Block (RTB) 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.
• If you connect or disconnect wiring while the field-side power is on, an electric 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.
• If you connect or disconnect the removable terminal block (RTB) with power applied, an
electric arc can occur. This could cause an explosion in hazardous location installations. The
removable terminal block (RTB) does not support “removal and insertion under power” (RIUP)
capability. Do not connect or disconnect the removable terminal block (RTB) while power is
applied. Be sure that power is removed before proceeding.
• If you insert or remove the module while backplane power is on, an electric arc can occur.
This could cause an explosion in hazardous location installations. Be sure that power is
removed before proceeding.
• Do not unscrew the RTB hold down screws and remove the RTB while power is on. This could
cause an explosion in hazardous location installations. Be sure that power is removed before
proceeding.
• Do not connect directly to line voltage. Line voltage must be supplied by a suitable, approved
isolating transformer or power supply having short circuit capacity not exceeding 100 VA
maximum or equivalent.

Mounting Dimensions and DIN Rail Mounting
DIN Rail Mounting
The module can be mounted using the following DIN rails: 35 x 7.5 x 1 mm (EN 50022 - 35 x 7.5).
For environments with greater vibration and shock concerns, use the panel mounting method,
instead of DIN rail mounting.
Before mounting the module on a DIN rail, use a flat-blade screwdriver in the DIN rail latch and pry it downwards
until it is in the unlatched position.
1. Hook the top of the DIN rail mounting area of the controller onto the DIN rail, and then press the bottom
until the controller snaps onto the DIN rail.
2. Push the DIN rail latch back into the latched position.
Use DIN rail end anchors (Allen-Bradley® part number 1492-EA35 or 1492-EAHJ35) for vibration or shock
environments.
To remove your controller from the DIN rail, pry the DIN rail latch downwards until it is in the unlatched position.
Panel Mounting
The preferred mounting method is to use two M4 (#8) per module. Hole spacing tolerance: ±0.4 mm (0.016 in.).
For mounting dimensions, see the Micro830®, Micro850, and Micro870 Programmable Controllers User Manual,
publication 2080-UM002
Follow these steps to install your module using mounting screws.
1. Place the module next to the controller against the panel where you are mounting it. Make sure that the
controller and module are spaced properly.
2. Mark drilling holes through the mounting screw holes and mounting feet then remove the module.
3. Drill the holes at the markings, then replace the module and mount it.
Leave the protective debris strip in place until you are finished wiring the module and any other devices.
