QCPort Starter Network
Adapter Product (QSNAP)
Product Description
The Cutler-Hammer
®
QCPort Starter
Network Adapter Product (QSNAP)
from Eaton’s electrical business is a
front-mount device providing commu-
nication capability, control and moni-
toring to Intelligent Technologies (IT.)
Electromechanical Starters, as well as
the S751 and S752 Soft Start, as listed
in Tables 76 78. The QSNAP allows
connection to any communications
adapter and provides access to any
support network.
The IT. QSNAP has an optional HANDS/
OFF/AUTO (HOA) module that enables
the starter to be operated in hand
mode; even if the QSNAP is not pow-
ered. The HOA option is used for cus-
tomers who need the extra security of
manual control in conjunction with
industrial network communication
capabilities.
With the addition of a D64 zero
sequence CT, the QSNAP can be
enabled to detect ground faults for
added protection.
