2.2 J1 & J6
– Inputs and Grounding
J1
– IF/RF Input
The IF/RF input connector is a 50 ohm coaxial connector (N or SMA Type). This connector is DC-blocked.
Do not /- 7VDC on this port.
J6
– Ground Terminal
A #10
–32 screw and lock washers are used to ground ATOM. Ensure the unit is grounded before powering
it on by a skilled person.
2.3 J3
– DC/AC Power
The 80W ATOM power input requires either 20V to 56V DC power (DC unit) or 3-phase 208V AC power
(AC unit). Each ATOM is supplied with a mating connector for the power interface. Only instructed person
may provide connection to the supplied connector per instructions below.
DC Power Option
The DC unit typically requires 20V to 56V DC power (80W ATOM). Refer to specific configuration of the
unit for the exact voltage range. Power is supplied through a four pin type cylindrical connector. Two pins
are used to deliver the positive connection and two pins are used for the negative connection in order to
reduce resistance. The negative connection is internally connected to case ground. The negative power
connection may alternatively be applied directly to the ground screw terminal on the aluminum housing.
Connector Type
The J3 connector for the DC unit is a four pin cylindrical connector (Amphenol® MS3102E22-22P). The
connector is a receptacle with pins and requires the mating connector to be a plug with sockets (e.g
Amphenol® MS-3106E22-22S). A range of plug-compatible mating connectors may be used to add options
to the plug such as right-angle, stress relief clamp, metal color/finish, etc. Please contact the connector
manufacturer for more information and/or refer to the Amphenol® catalog 12-070. Ensure the supply cable
is capable of supplying at least 540W of power (for 80W ATOM).
