Transmitter AC Connection
For conduit connections to the transmitter refer to the Outline Drawing Top View.
MULTI-CABINET NOTE:
AC Connections will be similar across all cabinets in multi-cabinet transmitter models.
Be sure to verify all connections using the correct schematic drawings.
!
WARNING:
DISABLE AND LOCK OUT STATION PRIMARY POWER BEFORE PRIMARY POWER
CABLES ARE CONNECTED TO THE EQUIPMENT.
NOTE:
The Atlas transmitter uses a 3-phase autotransformer. No neutral connection is
required in the cabinet. DO NOT run a neutral connection to the transmitter
as there is no connection point and the neutral should not be connected to
the cabinet ground. A safety ground wire is required and connects to E2 which
is shown in Figure 2-2 on page 2-17.
The Atlas Analogue transmitters are 3 phase 208/220/240Vac or 3 phase 380/400/
415Vac at 50/60Hz delta or wye. If voltage variations in excess of ±10% are
anticipated, the transmitter power input must be equipped with automatic voltage
regulators (optional equipment) capable of correcting the mains voltage.
NOTE:
It is important that the correct voltage be specified as the MOV protection com-
ponents are different for delta or wye configurations.
Connect the Primary AC conduit to the top of the transmitter cabinet.
The top of the transmitter cabinet has pre-cut holes for conduit connections as shown in
the Outline Drawing.
NOTE:
For the following two steps it may be helpful to remove the top access cover of
the transmitter.
Connect the AC wires to the primary AC terminal block TB5.
The AC input wires will connect to TB5 located on the ceiling of the transmitter (see
Figure 2-2, below). It will be necessary to use a screw driver to insert-and-pry open the
