Follow these steps to install the module:

Disconnect power. 2. Align the circuit board of module with the chassis card guide. (A) 3. Slide the module into the chassis until the bottom tabs lock into place. (B) 4. Route the wires down and away from the module, securing them with the wire tie. (C) 5. Cover all unused slots with Card Slot Filler, catalog number 1746-N2, to keep the chassis free from debris. 6. To remove the module, press and hold the module release located on each self-locking tab, and slide the module out of the chassis slot. (D)
Fuse Protection (1746-OBP16 and 1746-OVP16 modules) The fuse on the 1746-OBP16 and 1746-OVP16 modules (shown on Location of Jumpers and Fuses for 1746-OBP16 and 1746-OVP16 Modules on page 9) provides short-circuit protection for 13 mm2 (16 AWG) or larger wiring to external loads. In the event of a short circuit on an output channel, it is likely that the transistor associated with that channel will be damaged. In this event, the module should be replaced or the load moved to a spare output channel. The fuse does not provide overload protection. In the event of an overload on an output channel, it is likely that the fuse will not blow and the transistor associated with that channel will be damaged. To provide overload protection for your application, user-supplied fuses should be installed externally and properly sized to match your individual load characteristics.
