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 MicroSmar t is destined for Europe.
•
Do not connect any wiring to unused terminals.
•
Before turn on the power, make sure that wiring to the analog I/O module is correct. If wiring is
incorrect, the analog I/O module may be damaged.

•
When connecting a resistance thermometer, connect the three wires to RTD (resistance temper-
ature detector) terminals A, B’, and B of input channel IN0 or IN1.
•
When connecting a thermocouple, connect the two wires to terminals + and – of input channels
IN0 or IN1.
•
Do not connect any wiring to unused terminals.
•
Do not connect the thermocouple to a hazardous voltage (60V DC or 42.4V peak or higher).
