Precautions for Wiring

General Precautions
DANGER
⚫
Never change any wiring while power is being supplied in case of risk of electric
shock or injury.
WARNING
⚫
Wiring and inspections must be performed only by qualified engineers.
⚫
Check all wiring and power supplies carefully.
⚫
Incorrect wiring or incorrect voltage application to the output circuits may cause short-
circuit failures. If a short-circuit failure occurs as a result of any of these causes, the
holding brake will not work. This could damage the machine or cause an accident that
may result in death or injury.
⚫
Connect the AC and DC power supplies to the specified Drive terminals.
CAUTION
⚫
Wait for at least five minutes after turning OFF the power supply and then make sure
that the CHARGE indicator is not lit before starting wiring or inspection work. Never
touch the power supply terminals while the CHARGE lamp is lit after turning OFF the
power supply because high voltages may still be present in the Drive.
⚫
Observe the precautions and instructions for wiring and trial operation precisely as
described in this document.
⚫
Check the wiring to be sure it has been performed correctly.
Connectors and pin layouts are sometimes different for different models. Always
confirm the pin layouts in technical documents before operation.
⚫
Use shielded twisted-pair cables or screened unshielded multi-twisted-pair cables for
I/O Signal Cables and Encoder Cables.
⚫
The cable used for main circuit power to the Drive must be guaranteed to work at
75°C.
⚫
Observe the following precautions when wiring the Drive’s main circuit terminals.
•
Do not turn on the power supply to the Drive until all wiring, including the main circuit
terminals, has been completed.
•
Ensure that power is removed from the Drive before wiring connectors.
•
Insert only one wire per insertion hole in the main circuit terminals.
•
Ensure that conductor wires (e.g. whiskers) do not come into contact with adjacent
wires.
⚫
Install Type C MCB and other safety measures to provide protection against short
circuits in external wiring.
