Always follow your company's safety practices and
installation guidelines when installing an L900 MIU. Never
perform an installation during a lightening storm or under
excessively wet conditions.
Installation and operation in moderate temperatures increase
reliability and product life. See "L900 MIU Pit Environmental
Conditions" on page4.
Follow these guidelines when selecting a location to install the
L900 MIU.
l For best results, select a location where there is no chance that
another object can be set over the antenna.
l Avoid installing the L900 MIU behind metal fences or walls.
l Make sure the pit location gives adequate room for installing
both the L900 MIU and the pit antenna.
For maximum performance, the flange of the pit antenna
needs to be located above the pit lid.
l For maximum performance, Neptune recommends that pit
antennas be installed above the lid as illustrated in Figure 11.
