wiring requirements as specified in Section 2.03.
A. Connections to 208 / 230 - Volt Power
The 208 / 230 - Volt power supply includes a factory - installed input power cable for single - phase input power.
1. Check your power source for correct voltage before connecting the unit.
2. Connect the ends of the individual wires to a customer supplied plug or main disconnect as follows:
CAUTION
The primary power source and power cable must conform to local electrical code and the recommended circuit

B. Connections to 400 - Volt, 460 - Volt, or 600 - Volt Three - Phase Power
These Power Supplies are equipped with a four - conductor input power cable for three - phase input power. The 400 - Volt and
460 - Volt Power Supplies will accept Single - Phase input power with a change of input power cable.
1. The input cable's outer covering is stripped back at the factory to expose the individual wires at the free end
of the cable.
2. Connect the ends of the individual wires to a customer supplied plug or main disconnect as follows:
CAUTION
The primary power source and power cable must conform to local electrical code and the recommended circuit
protection and wiring requirements (refer to table in Section 2 ). All the input cable wires must be connected for three
