Figure 2-1 - Gateway Board Mounting Dimensions
The Gateway should be mounted in an environment
with ambient temperature between -40°F and 150°F, with a
non-condensing relative humidity between 5% and 95%.
Gateway boards are not supplied with an enclosure but
come with a snap-track for easy installation. The insulation
sheet and I/O board must be removed from the track before
the track is mounted. The snap-track is mounted using the
0.1875" mounting slots. Figure 2-2 shows this installation
procedure.

Table 3-1 - Gateway Power Requirements
The Gateway requires 24VAC power from a Class 2
center-tapped transformer.
CPC supplies several sizes of center-tapped transform-
ers for powering multiple 16AIs, 8ROs, and other RS485
peripheral boards of the E2, Einstein, and REFLECS sys-
tems.
Refer to your controller's user manual for information
on how to use the center-tapped transformers listed in Ta-
ble 3-1 to power multiple RS485 I/O devices for the US and
Canada.
Figure 3-1 shows how to connect the 56VA and 80VA
transformers to the Gateway power connector.
