Grounding
The VECTOR V1100 provides an external and internal grounding connection. The external
grounding connection accepts up to a 10 AWG [4 mm²] gage wire. The grounding conductor
is secured by means of a stainless steel screw, #10-32, with a captive washer. The internal
ground connection is attached to the metal housing and exits the threaded ½" NPT as a 14
AWG, (GREEN/YELLOW) lead wire. This grounding connection is typically tied to the internal
earth grounding terminal of the field device or junction box.
WARNING
Ground equipment as required by national, regional, local
electrical codes and practices.
Antenna Positioning
The VECTOR V1100 has an internal antenna which radiates out from top cap in a 360°
pattern. Position the VECTOR V1100 vertically and approximately one meter from any metal
or conductive material which could impact the wireless HART communications. The VECTOR
V1100 can placed anywhere on the current loop and does not need to be positioned directly
next to the field device. This allows positioning the VECTOR V1100 in an optimal location for
RF coverage.
The operating range can be reduced by interference from other nearby devices transmitting
in the 2.4 GHz ISM band. These external sources of interference can prevent the
establishment of wireless HART connection and may result in intermittent loss of network
connections causing HART network message retries. To maintain optimum antenna
performance periodically remove any accumulated material from the dome; such as, dust,
fiber, snow and ice. Use caution in removing any material off the resin dome so as not to
damage the dome or mechanically stress the NPT threaded connection.
