Model 2181 Electrical Installation
The Model 2181 Turntable is configured to operate using 200-230 VAC, single
phase, 50/60 Hz service. It is recommended to operate at this voltage level 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 inside the main bearing on one of the
bearing support blocks. 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.
3. The motor base assembly is provided with a non-terminated flexible
conduit with input power leads exposed. The flexible conduit is to be
terminated into a junction box fitted on or near the motor base. Terminate
the power leads of the motor base assembly according to local electrical
code requirements. 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 Model 2090 Series Multi-Device 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.
