• Connect a fuse appropriate for the applied voltage and current draw, at the position shown in the diagram. This is
required when equipment containing the MicroSmart is destined for Europe.
• When connecting a resistance thermometer, connect three wires B, B’, and A to the CS (current sense), +, and – termi-
nals of input channels IN0 through IN3, respectively.
• When connecting a thermocouple, connect the + wire to the + terminal and the – wire to the CS and – terminals.
• Do not connect the thermocouple to a hazardous voltage (60V DC or 42.4V peak or higher).
• Do not connect any wiring to unused terminals.
• – terminals of input channels IN0 through IN3 are interconnected.
