2.1.2 GMW87 and GMW88 transmitter parts
The enclosure of the IP64-rated GMW87 and GMW88 transmitter models differs from the
other GMW80 transmitter models. In GMW87 and GMW88, the screw terminal block is located
on the cover of the enclosure instead of the mounting base. Wires are led into the enclosure
either through a cable gland on the bottom of the mounting base or a sealed lead-through at
the back. The enclosure is opened and closed with 4 screws instead of the opening tab used in
other models.
