ZFR1811 Wireless Field Bus Router Installation Instructions

Mounting
When mounting the ZFR1811 Router to an enclosure,
mount it to the top, bottom, or side of the enclosure.
Do
not
mount the ZFR1811 Router in a horizontal
orientation. See Figure 2.
Location Considerations
Follow these guidelines when locating a ZFR1811
Router within a ZFR1800 Series System.
•
Locate the ZFR1811 Router so that it is easily
accessible.
•
For best signal transmission, vertically orient the
ZFR1811 Router with the flag end of the router
exposed below (and clear of) any pipes, duct work,
or other metal obstructions by at least 50 mm
(2 in.).
Do not
mount the ZFR1811 Router in a
horizontal orientation. See Figure 2 and Figure 3.
•
Due to the nature of the radio frequency waves, a
wireless device may have significantly different
signal strengths if its position changes relative to
another wireless device or if its environment
changes. If a ZFR1811 Router shows poor signal
strength, you may be able to improve the signal
strength by rotating the ZFR1811 Router.
•
Locate the ZFR1811 Router in line-of-sight with as
many ZFR1811 Routers and WRZ Sensors as
possible.
•
Do not mount the ZFR1811 Router in recessed
areas, metal enclosures, or shelving units.
Note:
For detailed information on location guidelines
for a ZFR1800 Series system, and for estimating the
number of ZFR1811 Routers needed as repeaters for
extending wireless transmission range, refer to the
ZFR1800 Series Wireless Field Bus System Technical
Bulletin (LIT-12011295)
