ELECTRICAL INSTALLATION
The Model 2303 Positioner is designed to operate using 208/230 VAC single phase
50/60 Hz power. The motor drive will not operate on a lower voltage, such as 110
VAC. The power inlet assembly has an integral 10 A fuse. Normal current draw for
the drive is less than 6 A. The branch circuit supplying power to the motor drive
must be protected from excess current according to local electrical codes.
Ensure the distance from the mains power source is appropriate for the wire
gauge used and that the wire gauge is adequate for the motor load.
Prior to servicing the turntable, remove the power connection. Trigger, Reset, Fiber
Optic connections are found on the Control 3-Axis box (PN 1725357).
High Voltage:
Unsafe practice could

Turntable Electrical Installation
The 2303 Turntable is configured to operate using 208/230 VAC, single phase,
50/60 Hz service. This voltage level is recommended for operation to reduce the
surge currents necessary to power an electric motor.
1. The branch circuit supplying power to the motor base should be protected
from excess current according to local electrical codes. An integral circuit
breaker is mounted on the control box. The circuit breaker is specifically
designed for the inductive load presented by the electric motor.
2. Make sure the conductor size is adequate for the motor load and the
distance from the mains source. Improperly sized conductors will lead to
a high voltage drop in the power conductors and cause reduced starting
torque and premature motor failure.
Following is the conductor color code:
Brown: AC high
Blue: AC neutral
Green/Yellow: Protective earth/safety ground
Connect the fiber optic control cable and install the power connection
according to local electrical code. See the controller manual for information on
connecting the fiber optic cable. After the fiber optic cable is installed, secure it
with a wire tie to one of the leveling screws.
To feed the fiber optic connectors through a waveguide in the chamber, cables
are included to connect from the feedthroughs on the penetration panel to the
controller and motor base.
Electrical installation
must be performed by
a qualified electrician,
and in accordance
with local and national
electrical standards.
High Voltage:
Unsafe practice could
result in severe personal
injury or death.
Do not, at any time,
place hands or feet in
the vicinity of the drive
pinion on the turntable.
Stay clear of all moving
components.
