Internal connectors
CMOS Battery
The CMOS battery supplies the necessary power required to maintain the CMOS settings and configuration data in the UEFI flash
chip. The specified battery type is CR2450N(3V, 540mAh) or CR2477(3V, 950mAh). Because the self-discharge of all lithium batteries increases
rapidly at high temperatures the battery life time decreases by a great amount. To prevent battery leakage scheduled service/replacement is
recommended. Please contact the battery manufacturer for further details and calculation assistance for battery life time calculation.
Fuse
The main fuse protects the system against destruction in case of high energy distortions on the power line. For replacement, the system must be
opened in an ESD protected environment. Only an entitled instructed person is allowed for this operation. Replacement fuse type is Littelfuse
452004.MRL (4A slow-blow).
USB 2.0
Depending on the installed PC board the PROTOUCH-8 offers several internal USB connectors whereof one is used to connect the touchpanel.
Please contact technical support for further details and assistance.
