3.3.1 Chassis Ground Interfaces
CAUTION – PROPER GROUNDING PROTECTION IS REQUIRED. THE INSTALLATION
INSTRUCTIONS REQUIRE THAT YOU MUST ENSURE THE INTEGRITY OF THE
PROTECTIVE EARTH AND THAT YOU MUST MAINTAIN THE EQUIPMENT'S
CONNECTION TO THE PROTECTIVE EARTH AT ALL TIMES.
THE CRS-300 IS DESIGNED FOR CONNECTION TO A POWER SYSTEM THAT HAS
SEPARATE GROUND, LINE, AND NEUTRAL CONDUCTORS. THE EQUIPMENT IS NOT
DESIGNED FOR CONNECTION TO A POWER SYSTEM THAT HAS NO DIRECT
CONNECTION TO GROUND. IT IS THEREFORE IMPERATIVE DURING INSTALLATION,
CONFIGURATION, AND OPERATION THAT YOU PROPERLY GROUND THE UNIT USING
THE GROUND STUD PROVIDED ON THE REAR PANEL OF THE UNIT.
Use the #10-32 stud, located adjacent to the power interface on the CRS-230 or CRS-250 Power
Supply Module (Figure 3-1), for connecting a common chassis ground among equipment.
The AC power interface provides the safety ground.
