3.4.1 Supply
Power
The outdoor models of the Gateway enclosure are supplied with two holes for 3/4”
conduit in the bottom of the enclosure. The installer must use the proper fittings to
maintain the weatherproof integrity of the enclosure.
The manufacturer does not
recommend adding additional holes to the enclosure. However, if additional
holes are added, proper Type 4 seals must be used to prevent water from
leaking into the enclosure.
The indoor models of the Gateway are supplied with two bushings installed for the
user to connect DC supply and the Ethernet cable (if used for your model).
The Gateway is a Category II device.
The outdoor models of the Gateway require an external SELV source of 12-24V
DC.
The indoor models of the Gateway require the use of a 12 – 24V DC supply.
The wiring must be in accordance with any national, state and/or local regulations.
This equipment is considered Class 1 which uses a protective earth ground.
Verify that the cables from the cover to the printed circuit board are properly
connected. Close the cover and secure the two latches.
Fuses F1 and F2 are permanently soldered on the PCB. They are installed only for
catastrophic failure and are not considered serviceable by an end user. The
connections for this power are located as follows:
