Safety Grounding Procedures
Each power supply has an M5 stud, starwasher, and nut on the rear
panel for connecting to earth ground. Both power supplies should be
connected to earth ground using a minimum 1.3 mm
with a suitable Listed/Certified M5, or equivalent crimp-on ring
terminal.
This equipment must be connected to earth ground to assure
continued safe operation, to prevent damage from electrostatic
discharge, and to assure compliance with electromagnetic
compatibility requirements.

Connecting the Power Supply

Disconnect power from the source before connecting power to
the product or before accessing the product's power terminals.
The DC source can supply high levels of current capable of
causing serious burns and arcing that can produce molten metal.
The steps required to connect the power supply are:
1. Connect the earth ground cable.
2. Connect the DC power cable.
3. Attach the cable strain relief.
4. Verify the power supply is installed correctly.
