Opening and Closing Enclosures

Procedures for opening the IND570 terminal panel-mount and harsh enclosures differ and are
described in the following sections.
2.1.1. Panel-Mount Enclosure
The panel-mount version of the IND570 is opened by removing the three Phillips-head screws on
the back panel (see Figure 2-1). The rear panel can then be removed to gain access to the internal
workings of the terminal.
2.1.2. Harsh Enclosure
2.1.2.1. Opening the Harsh Enclosure
The front panel of the harsh enclosure IND570 terminal is locked in place by four spring clips
attached to the enclosure body. These four clips are located toward the corners of the enclosure.
Two additional clips can be found along the sides of the enclosure. These two clips do not engage
with the front cover, and are only there to guarantee proper placement and spacing during
installation of the front cover on to the enclosure.
To gain access to the terminal's PCB for internal wiring and setting switches, separate the front
panel from the enclosure as follows:
1. Place the harsh terminal on a stable, flat surface, with its front panel facing up.
2. Preferred method: Insert the metal part of the clip release tool, Figure 2-2, (for the order
