Power Options
The standard Scanner 2000 microEFM can be powered two ways:
• with the internal lithium battery pack supplied with each Scanner 2000 (shown in Figure 1.5)
• with an external customer-supplied power supply (6 to 30 VDC); the lithium battery provides backup
power when an external power supply is used
Wiring diagrams are provided in Section 3—Wiring the Scanner 2000.
Foundation™ eldbus models are powered by a customer-supplied eldbus power supply. In the event that
eldbus power is lost, the lithium battery will help ensure that timekeeping and volume accumulation will not
be interrupted. See Appendix C—Scanner 2000 for Foundation™ Fieldbus for details.
