SECONDARY DISCONNECT
ETHERNET DISCONNECTS
Ethernet Secondary Disconnects are secondary dispenser wiring
disconnects designed to expand the number and type of cabling that
can be disconnected. They are designed for dispensers that use
Ethernet network cabling for secondary dispenser communication.
Models are available that will disconnect 1 or 2 Ethernet cables for 8
dispensers or disconnect 1 Ethernet cable for 16 dispensers.
HIGHLIGHTS
• Secondary Ethernet disconnect expands the capability
of the primary disconnect.
• Additional secondary expansion disconnects can be
added now or in the future.
• Wall mounted.
• Individual disconnects for each circuit types allows the
disconnect to be located where the conductors enter the
building. This can eliminate costly additional wiring and
downtime that maybe required to re-route conductors to
a central location such as the electrical room, during a
retrofit or site upgrade.
• Aids in compliance of the NFPA® and NEC® codes.
• Suitable for new and retrofit applications.
• Connects to and controlled by any primary disconnect.
• Secondary disconnect models connect to the primary
disconnect allowing secondary circuit conductors to
be disconnected when the emergency stop system
is activated.
