2150EX AV Flow Module - Isco

2150EX Area Velocity Flow System
Section 2 Preparation and Installation
Two interface cable assemblies are available from Teledyne Isco:
The CA75EX-CTL, 75 meter (60-2004-337) provides the
maximum length for powering two 2150EX modules with
sensors. The CA150EX-CTL, 150 meter (60-2004-338) provides
the maximum length for powering one 2150EX module with
sensor. Maximum length may require reduced-power program
settings. Contact the factory for custom-ordered lengths less than
standard. Install the interface cables without coiling and cut to
the appropriate practical length. Wire the interface cable to the
2194EX using the Network Interface Connector Wiring Kit
(60-2004-468), referring to Figures 2-13 through 2-17. Always
comply with the clearly labeled entity parameters for hazardous
location installations.

Observe intrinsic safety requirements regarding proximity to
external sources of potential electric or magnetic interference.
Refer to IEC 10079-14 Section 12.2.2.5 on installation of cables
and wiring.
WARNING
Do not coil the interface cable; this will form an inductor
and create a hazard. The cable should be kept as short as
is practical.
Teledyne Isco strongly recommends that you route the
interface cable through conduit between the safe and hazardous
areas. Two different sizes of conduit fittings are provided
with the connector wiring kit (Figure 2-15).
