Note 1. Ampacity is based on a single conductor in free air, 26-30 °C ambient temperature, with the conductor rated at
60 °C. Ampacity ratings decrease when wires are bundled an at higher ambient temperatures.
Note 2. Resistance is in ohms/1000 feet, at 20 °C wire temperature.
Along with conductor temperature, you must also consider voltage drop when selecting wire sizes. Although the power
supply will compensate for the voltage in the load wires, it is recommended to minimize the voltage drop as much as
possible to prevent excessive output power consumption from the power supply and poor dynamic response to load
changes. Larger diameter wire sizes will help minimize load-wire voltage drops. Twisting or bundling load wires will help
reduce transient voltage drops.
Single Load Connections
As shown in the following figure, terminate all load wires with the proper wire terminal lugs securely attached. DO
NOT use unterminated wires when making connections at the power supply.
The following figures illustrates the recommended hardware sizes. A hardware kit is shipped with your unit. You must
provide the cables and terminations. Ensure that the cable-mounting hardware does not short the output terminals.
