340CF ELSD
Section 3 Installation
3.1 Unpacking
Unpack carefully and confirm that all the items are present. The
ELSDs come in a high quality shipping container, engineered to
avoid damage in transit. Save the shipping container and pack-
aging for future shipments.
3.2 Connections
The following sections provide general connection information for
the ELSD unit. For information about connecting the ELSD to
Teledyne Isco instruments, refer to Section 3.3.
3.2.1 Power
The ELSD operates at 120V or 234V, 50/60 Hz. Confirm that the
ELSD is configured for the correct voltage before plugging it into
line voltage. The voltage configuration is listed on the serial tag.
If the voltage listed is incorrect, please contact your local
Teledyne Isco representative.
Plug the modular power cord provided into the power input
module on the back of the detector. The power cord is the dis-
connect device for the unit. Therefore, select a power outlet that
is nearby and unobstructed, allowing easy access for discon-
nection in the event of an emergency.
3.2.2 Exhaust
The ELSD exhaust is a ½" O.D. stainless steel tube. Use ½" I.D.
tubing to connect to a fume hood during operation. Alternately,
connect tubing and direct to a cooled collection vessel for later
disposal.
3.2.3 Location
The ELSD rear panel has a fan for cooling. Position the
instrument so that the rear panel is at least 5cm from any wall or
object, to allow free movement of air.
3.2.4 Communication
An output jack can be found on the back of the ELSD for con-
nection to The CombiFlash Rf200. The maximum signal output is
5V.
CAUTION
Observe polarity when connecting to this output. Refer to
Section 3.3 for complete details about connection.
