Grounding the WMT52
The normal way to ground the WMT52 is to install it on a mast or a
cross arm that provides a good connection to earth ground. The
grounding is provided via the fixing screw (or mounting bolt), so it is
important that it makes a good ground connection. If the surface of the
mounting point is painted or has some other finishing that prevents a
good electrical connection, consider using the Bushing and Grounding
Kit and a cable to provide the ground connection.
Grounding using the Bushing and Grounding Kit
If necessary, you can run a cable from the fixing screw to a grounding
point. A Bushing and Grounding Kit (Vaisala order code: 222109) is
available for this purpose. The kit includes a longer fixing screw, two
nuts and washers, and an Abiko connector for the grounding cable.
Refer to
for an illustration on how to assemble and
install the kit.
The kit does not include the grounding cable. Use a 16 mm
2
(AWG 5)
conductor to achieve a good ground connection.
