11.1 Connecting Wires to the Pulse I/O Terminals
168
This section describes how to connect wires to the pulse I/O terminals. When using
pulse output, the signal must be pulled up to the external power supply.

11.1 Connecting Wires to the Pulse I/O Termi-
nals
To avoid electric shock or damage to the equipment, always
observe the following precautions when connecting to pulse
input and output terminals.
• Always turn off the power to the instrument and to any
device
s to be connected before making connections.
• Be careful to avoid exceeding the ratings of pulse
input and
output terminals.
• During operation, a wire becoming dislocated and contact-
ing anothe
r conductive object can be serious
hazard.
Secure the pulse input and output terminals.
• Ensure that devices and systems to be connected to the
pu
lse input and output terminals are properly isolated.
To avoid electric shock, use the recommended wire type to con-
nect to the current input terminals, or otherwise ensure that the
wire
used has sufficient current handling capacity and insulation.

1
Press down on the terminal button using a tool, such as a flat head screw-
driver.
2
While the button is depressed, insert the wire into the electric wire connec-
tion hole.
3
Release the button.
The electric wire is locked in place.
