Isco 4700 Multipurpose Cable
Preparation and Functions
Overview
The terminated end of this multipurpose cable connects to the 16-pin connector on the back side of the
4700 refrigerated sampler. The unterminated end can be
wired to compatible circuits for interfacing with the
sampler. These instructions explain how to prepare the
cable for use, as well as the function of each wire.
CAUTION
WARNING
Ensure that no wire ends come into contact with
each other. Personal injury, power shutdown, or
component failure can result.
Wires not in use should be individually sealed at
all times.
Standard 10’ Length
part #69-4704-041
Risk of equipment damage. Only experienced electronic
technicians should make the connections to an external
device using this cable.
Ensure that the connection has protection from the
environment, such as running the cable through conduit
and making the connections inside a watertight
electrical box.
