Sam4POS Quick Start v1.1 Introduction - 11 -
Power Requirements
Plug the Sam4POS terminal into a grounded 3-prong outlet.
• Be aware that other electrical devices on the same circuit can cause your ECR to malfunction.
Avoid plugging your ECR into outlets where other high-current devices are connected.
• Be aware that power quality issues, including voltage fluctuations, electrical noise, spikes,
outages, interruptions, and other power viruses can disrupt or damage modern electronic
equipment, including ECRs and PCs.
• When ECRs are interconnected in networks, connected to PCs or where communications
cables connect peripherals, particular care must be taken with power sources and
communication cable routing. Your authorized dealer can provide detailed power
specifications for these applications. Failure to implement installation requirements for
networked systems may cause system failures and/or poor system performance.
• The Sam4s Sam4POS-500 is a modern computerized network device. As with all network
systems, it requires appropriate electrical power wiring and proper routing of communication
cabling for reliable operation and maximizing the life of the equipment.
• When installed in a merchant location, CRS recommends a PowerVAR ABC065-11 power
conditioner, CRS P/N 701002. An uninterruptible power supply (UPS) is recommended
where frequent power disruptions occur. Without a UPS, the SAM4POS-500 will shut down
and reboot when power is disrupted. (The SAM4POS-500 reboots in less than one minute.)
CRS also recommends:
• Dedicated branch circuits for Sam4POS-530 equipment.
• Isolated Grounding for all equipment within the Sam4POS-500 system.
Safe Operation
Do not locate your Sam4s Sam4POS-500 in a damp or wet environment. Avoid high
humidity, direct sunlight and temperature extremes.
Always plug your Sam4POS-500 into a grounded three-prong outlet. Never use two-prong
adaptors or ungrounded outlets.
Check to make sure the power outlet provides the correct voltage: (120V +/- 10%).
Immediately disconnect the ECR from the power source in case of spilled liquid in the ECR,
smoke, or strange smells. Call your authorized dealer for assistance.
Do not operate the ECR with wet hands.
Use a soft dry cloth to clean the ECR cabinet. Do not use wet cloths or solvents.
Do not open the ECR case to attempt repairs. Dangerous voltages can cause shock. Service
attempts by untrained personnel can cause unnecessary damage to your ECR.
