equipment designed for nominal 24 volts. The maximum battery voltage should never exceed the
maximum specified input voltage.
Mounting the Enclosure
N OTE : The enclosure is intended for indoor use only.
Mount the enclosure using the four 0.312-inch (8 mm) diameter holes located on the mounting flanges
with ¼-inch (M6) hardware. The 370-301 is not supplied with conduit or cable openings.
Remove the front panel and drill or punch entry openings in the rear section of the enclosure
Refer to Figure 2 for the suggested locations. There must be a minimum of ½ inch (13 mm) of material
between entry holes. The station is suitable for top or bottom entry per Figure 2. However, GAI-Tronics
recommends bottom entry only wherever possible.
The standard orientation shown in Figure 2 locates the power supply housing in the upper left corner.
The orientation of the enclosure can be rotated 180º to allow clear access to the top.
The 69856-xxx PCBA can then be rotated for correct orientation.
For specific details including mounting hole dimensions, refer to Figure 2. When mounting the enclosure,
use caution to avoid damaging the internal components.
