5. To maintain the proper spacing between the turntable and the
ground ring, it may be necessary to shim or pull the ground
ring into position before fastening.
ELECTRICAL INSTALLATION
CAUTION It is important that this electrical installation procedure
be performed by a qualified electrician, in accordance with local
and national electrical standards prior to energizing the unit.
The Model 2087 is configured to operate using 230 VAC, single
phase, 50/60 Hz service. It is recommended to operate at this
voltage level to reduce the surge currents necessary to operate an
electric motor.
1. The branch circuit supplying power to the motorbase 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. Check to ensure that 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 an unterminated
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. The
following conductor color code is observed:
Brown: AC high
Blue: AC neutral
Green/Yellow: Protective Earth/Safety ground
