Wiring Procedure

A terminal cover is screwed in place on the
measuring input terminal block on the rear panel.
A label indicating the terminal arrangement is
affixed to the cover.

1.

Turn OFF the recorder and remove the

terminal cover.

2.

Connect the signal wires to the terminals.

Note

Input signal wires of diameter less than or equal to 0.3 mm may not be secured firmly for
clamped terminals (/H2). Fold over the conducting section of the wire, for example, to make
sure that the wire is securely connected to the clamped terminal.

3.

Replace the terminal cover and fasten it with screws.

The proper torque for tightening the screws is 0.6 N•m.

Leadwire resistance:

10 Ω max./wire. The resistance

of the three wires should be

equal.

Example:

For a 4 to 20 mA input,

a shunt resistor of

250 Ω ± 0.1% can be used

to convert to 1-5V input

Note

RTD input terminals A and B on the dot model are isolated on each channel. Terminal b is
shorted internally across all channels. However, for 3 legs isolated RTDs (/N2 option), input b is
also isolated for each channel.
