Mounting the Barrier on a DIN Rail Before Installing Modules

The 1797-BCNR module mounts on a DIN rail.

1. Position the ControlNet Ex barrier module (A) on a 35 x 7.5mm DIN

rail (B) (A-B pt. no. 199-DR1) at a slight angle.

2. Hook the lip on the rear of the barrier (A) onto the top of the DIN

rail (B), and rotate the module onto the rail.

3. Press the barrier module down onto the DIN rail until flush.

4. The locking tab (C) should snap into position and lock the barrier

module to the DIN rail.

5. If the barrier module does not snap into position, use a screwdriver or

similar device to move the locking tab down while pressing the barrier

module flush onto the DIN rail. Release the locking tab to lock the

module in place.

6. If necessary, push up on the locking tab to lock.

7. Make certain that you only connect the ControlNet Ex side of the

1797-BCNR to 1797 ControlNet taps with either a 1797-ACNR15 or

a 1797-TCAP attched.

WARNING

The 1797-BCNR cannot be used in an intrinsically safe

environment after the ControlNet Ex connections have been

exposed to non-intrinsically safe signals.
