Payload EM Board Operation Guide

Connecting the Board to Power

WARNING: Throughout this process, make sure that the positive and negative power lines DO NOT TOUCH. Keep them well away from each other to prevent a short from happening

1. Put on the ESD wrist strap, ensure that it is connected to the ESD mat and that the ESD mat is grounded

2. Make sure the power and ground pins are NOT connected to the variable power supply, to prevent accidental shorts

3. While the variable power supply is NOT connected to the EM board, turn on the variable power supply and:

   1. Make sure it is on Constant Voltage (C.V.)

   2. Set it to 6.40 V

   3. Turn off the power supply

   4. Hook up the multimeter to the power supply and set the multimeter to measure voltage

   5. Turn on the power supply

   6. Check the voltage using a multimeter

   7. Turn off the variable power supply

4. Plug the ground cable onto the PWR_NEG pin on the board

5. Plug the power cable onto the PWER_POS pin on the board

6. Connect the ground cable to the variable power supply's negative (black) power terminal with the alligator clip

7. Connect the power cable to the variable power supply's positive (red) power terminal with the alligator clip

8. Turn on the variable power supply
