1. Position the remote I/O adapter module A on a 35 x 7.5mm DIN rail
B (A-B pt. no. 199-DR1; 46277-3; EN 50022) at a slight angle.
2. Hook the lip on the rear of the adapter (A) onto the top of the DIN rail
(B), and rotate the adapter module onto the rail.
3. Press the adapter module down onto the DIN rail until flush. Locking
tab (C) will snap into position and lock the adapter module to the DIN
rail.
4. If the adapter module does not lock in place, use a screwdriver or
similar device to move the locking tab down while pressing the
adapter module flush onto the DIN rail and release the locking tab to
lock the adapter module in place. If necessary, push up on the locking
tab to lock.
5. Connect the adapter wiring as shown under “Wiring” later in this
document.
NOTE: For Panel/Wall mounting, refer to publication 1794-5.13, “Panel
Mounting Kit, Cat. No. 1794-NM1.”
