Grounding - GE PACSystems RX3i CPE400 Quick Start Manual

Overvoltage protection
In the CPE400, the voltage to the inner loads is clamped to 33Vdc. At 33Vdc, the
internal clamping diode starts conducting at 1mA. Any further increase in the voltage
will cause the internal current fuse to blow and/or the clamping diode to break.

CAUTION – EQUIPMENT REPAIR REQUIRED – Internal components must be
repaired at the factory; they are not field replaceable. Contact the GE
support team at
Overcurrent protection
The function protects the internal circuitry from overcurrent conditions before serious
damage can occur, such as overheating of the equipment. The fuse is rated for 4A
continuous current. Once the sensed current reaches 40A, the fuse will blow after a
period of 10ms to 100ms.

Grounding

Grounding via the FGND connection on the 3-pin 24Vdc In power header is
recommended (see section 2.4), but is not required if the CPE400 is mounted to a
grounded metal panel. Furthermore, if an Energy Pack is connected, be sure to
comply with grounding procedures as described in PACSystems RX3i Rackless Energy
Pack IC695ACC403 Quick Start Guide, GFK-3000.
