Observe intrinsic safety requirements regarding proximity to<br />
external sources of potential electric or magnetic interference.<br />
Refer to IEC 10079-14 section 12.2.2.5 on installation of cables<br />
and wiring.<br />
If the <strong>2150EX</strong> and <strong>AV</strong> <strong>2150EX</strong> sensor are not located in a potentially<br />
explosive atmosphere, the RS232EX isolator cable can be<br />
connected directly to the top of the <strong>2150EX</strong>.<br />

2.6.3 Connecting to a 2100<br />
Series Network Device<br />
The <strong>2150EX</strong> can be connected to a 2100 Series network device<br />
located in a safe area (with the exception of the 2102 Wireless<br />
module). In order for the <strong>2150EX</strong> to communicate with a 2100<br />
Series network device other than the 2194EX, the two must be<br />
connected by an <strong>Isco</strong> RS485EX Isolator Cable (P/N 60-2004-340).<br />
The hazardous area end, labeled with proper entity parameters,<br />
connects to the EX Network cable.<br />
Observe intrinsic safety requirements regarding proximity to<br />
external sources of potential electric or magnetic interference.<br />
Refer to IEC 10079-14 section 12.2.2.5 on installation of cables<br />
and wiring.<br />
If the <strong>2150EX</strong> and <strong>AV</strong><strong>2150EX</strong> sensor are not located in a potentially<br />
explosive atmosphere, the RS485EX isolator cable can be<br />
connected directly to the top of the <strong>2150EX</strong>.<br />
