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.
