Enclosure The ControlWave ExpressPAC enclosure is a standard NEMA 3R
rated fiberglass enclosure. The enclosure consists of the body and the
front cover. A continuous gasket seals the unit when you close the
front cover. Two latches on the enclosure’s right side secure the cover.
The enclosure includes a weatherproof connector (local port) mounted
to the bottom of the cover and connected internally to RS-232 COM
port 1.
The enclosure includes a display or display/keypad for an operator or
technician to view process values locally.
