2150EX Area Velocity Flow Module
Section 2 Preparation and Installation
2-24
Series network device other than the 2194EX, the two must be
connected by an Isco RS485EX Isolator Cable (P/N 60-2004-340).
The hazardous area end, labeled with proper entity parameters,
connects to the EX Network cable.
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.
If the 2150EX and AV2150EX sensor are not located in a poten-
tially explosive atmosphere, the RS485EX isolator cable can be
connected directly to the top of the 2150EX.
A site example using the Field Wizard is shown in Figure 2-2.
Figure 2-18 RS485EX Isolator Cable for Connection to a 2100 Series Network Device
To connect the EX Network and RS485EX isolator cables:
1. Remove the protective cap from the communication
connector on the top of the 2150EX module.
2. Store the protective cap in the holder next to the connector.
3. Push the 6-pin end of the EX Network cable onto the com-
munication connector on the top of the 2150EX module.
