EEC 85xx Power Supply Connection
Introduction
This application note provides essential guidelines for proper connection of the 8500 series power supply to ensure safe and reliable operation. Adhering to these recommendations will help prevent damage to both power supply and connected devices.
1. Input Voltage and Current
A dedicated mains power source of 100 – 240V AC ± 10%, (50/60Hz ) single phase is required for models 8505, 8512, and 8520. Models 8530 & 8540 require a 200 – 240V AC ±10%, (50/60Hz) balanced/single phase input source. Please read the sticker on the rear panel of the instrument to be sure the proper input voltage is provided before powering your instrument ON. Model 8560 requires a 200 - 240V ± 10% single phase / 3 phase input source or a 346 - 416V ± 10% 3 phase input sources.
| Models | 8505 | 8512 | 8520 | 8530 | 8540 | 8560 |
| Input Voltage | 100-240V±10% | 200-240V±10% | 1Ø/3Ø3W: 200-240V±10%; 3Ø4W: 346-416V±10%; |

| Input Current Max | 8A | 18A | 30A | 22A | 30A | 1Ø: 45A; 3Ø3W: 38A; 3Ø4W: 22A |
The following chart lists the wire configuration that must be used for connection to the input and output of the different models:
| Models | INPUT | OUTPUT |
| 8505 | 14AWG/2.08mm² | 22AWG/0.326mm² |
| 8512 | 12AWG/3.31mm² | 16AWG/1.31mm² |
| 8520 | 12AWG/3.31mm² | 14AWG/2.08mm² |
| 8530 | 12AWG/3.31mm² | 12AWG/3.31mm² |
| 8540 | 12AWG/3.31mm² | 10AWG/5.26mm² |
| 8560 | 1Ø2W: 8AWG/8.37mm² 3Ø3W:10AWG/5.26mm² 3Ø4W: 12AWG/3.31mm² |
6AWG/13.3mm² |
The rear panel terminal covers should be used to prevent electric shock. The input/output terminals must be covered when using this product.
2. Connections and Wiring:
Choose appropriate mains power and follow the connection diagram listed below for the type of power that is available. Use the correct connectors rated for the application and secure each connection to prevent power issues.
Before connecting power to this instrument, the protective ground (earth) terminals of this instrument must be connected to the protective conductor of the line (mains) power cord. The main plug shall only be inserted in a socket outlet (receptacle) provided with a protective ground (earth) contact. This protective ground (earth) must not be defeated by the use of an extension cord without a protective conductor (grounding).
