4-2 Installation Issued Nov-09
IStran. Do not install any other wiring through the same hole or allow
other wires to share a cable or conduit with the intrinsically safe wiring.
Secure the intrinsically safe wiring and limit slack to ensure that, should
one of the intrinsically safe wires become dislodged from an IStran
terminal, it must still maintain a 2” separation with either the IStran
non-hazardous interface wiring or any other circuits except those on the
IStran hazardous interface.
Refer to Figures 3-1 through 3-4 in Chapter 3 when you connect wires
between an optional modem or radio and an IStran assembly.
Note: MDS and Freewave radios use different RXD/TXD naming
conventions. MDS uses RXD and TXD to mean “receive input”
and “transmit output” respectively, while Freewave uses RXD
for “transmit output” and TXD for “receive input.”
Refer to Chapter 3 when you connect wires between an externally
powered CW-GFC-IS and an IStran.
