Pepper Computer RS485, RS232 user manual SCR2

SMART I/O User’s Manual Introduction

An on-board fuse protects the 24V DC input circuitry from damage through higher voltages than those expected or AC voltages being inadvertently applied to the system. This fuse, should it be assumed defect (the Power In LED on the housing will not be illuminated), may be accessed by removing the cover of the SMART-BASE and accessing the holder on the left-hand side as shown in the illustration below.
