Starting Up
Please consider the Hints included in the chapter 4 “General Safety Instructions for IT Equipment”.
When used as intended the KISS 4U V2 EATX platform is to operate only closed and locked.
Only when the cover is properly installed, secured with the knurled screws on the rear and the cover
fastening screw on the front, and the access panel is locked with the key, it is ensured that the user
doesn’t have access to the internal parts of the KISS 4U V2 EATX platform, loaded with hazardous
energy.
The rated voltage of the AC or DC mains must agree with the voltage value on the type label.

To connect the KISS 4U V2 EATX platform to an AC power supply, perform the following steps:
1. The KISS 4U V2 EATX systems with grounding studs marked with a PE symbol have to be grounded by establishing a
large-area contact between the grounding stud (at the rear side) and an appropriate grounding connection point (see
chapter 7.3.3 “Grounding Stud”, Fig. 27 and Fig. 28).
2. Connect the AC power cord to the AC input connector.
3. Connect the other end of the AC power cord to a corresponding mains outlet.
Make sure that the mains power supply (power outlet) is properly grounded and that the power cord is
in perfect condition without any visible damage. An ungrounded power supply is not permissible.
