DANGER
Do not touch the pins of this connector.
●
Do not touch the rear side of the I/O backplane.
●
Connectors: "DP0", "DP1". Maximum voltage: +90V DC .
NOTICE
Observe the correct polarity of the drive power supply connections.
If the cable has a shield, connect the shield at the system housing side to the
shield pin in the connector or the connector housing. It is recommended that
the shield of the cable at the power supply side is connected to the chassis of
the power supply unit, not to the PE connection.
All drive power cables must be installed with some form of a strain relief
underneath the system housing. If the drive power cable has a shielding, this
shielding must make a good quality electrical contact with the strain relief
bracket.
Make sure that the power supply cable diameter is suitable for the maximum
rated current.
If the drive power supply for the drive modules is not installed near the system
housing, put a warning on the connector at the drive power supply side stating
that when the connector is disconnected a high voltage can remain present on
the pins of the connector for 5 minutes.
A fuse must be installed between the power supply output voltage and the drive
power input voltage connection. The rating of the fuse depends on the used
cables and application requirements of the motion profiles.
Fuse rating for UL fuses.

Voltage on the pins of this connector can be
higher than 60V DC. When the connector is
unplugged a high voltage can remain present on
the pins for 5 minutes after disconnection. If
the drive slot has an accompanying capacitor
installed and the drive module is not installed in
that slot, you must wait 30 minutes.
The system housing has no provisions against
wrong polarity connection of the DP power
supply.
