Wiring PG Speed Option Card Terminal Blocks
Use no more than 100 meters (328 feet) of wiring for PG signal lines, and keep them separate from power lines.
Use shielded, twisted-pair wires for pulse inputs and pulse output monitor wires, and connect the shield to the shield
connection terminal.

Solderless Terminals for Control Circuit Terminals
The use of solderless terminals for the control circuit terminals is recommended because solderless terminals are
easy to connect securely.

NOTE:
Do not solder wires with the control circuit terminal if wires are used instead of solderless terminals. Wires many not contact
well with the control circuit terminals or the wires may be disconnected from the control circuit terminals due to oscillation if the
wires are soldered.
