Auto Passport® All-In-One Reader/Antenna Power Requirements
Power for the Auto Passport reader/antenna is supplied by the Auto Sentry flex.
The Auto Sentry
flex
has terminal blocks located inside the base for power termination.
Wire Gauge and Conduit Size
When planning the orientation of the wiring runs, follow the applicable ICS wiring diagrams and consider the layout of the
components at the site. To determine conduit size needed, see the table below for more information.

Recommended and Accepted Grounding Methods
The Auto Passport equipment must be properly grounded. Proper system grounding is an extremely important part of the system
installation. Grounds for all devices should be wired to the main service electrical panel ground bus bar which, in turn, should be
grounded to a ground rod. A conduit ground does not provide a sufficient ground. It is recommended that the neutral and ground bus
bars be bonded together when it is not prohibited by local codes.
The universal ground symbol identifies the grounding terminal
located in the Auto Sentry unit near the terminal blocks.
WARIGE:
Failure to properly ground the unit
could result in unit failure and/or bodily
injury. Ground wire must be connected
to the ground terminals.
NOTE:
Improper grounding will void equipment warranty.
