MicroSale POS terminals and printers rely on a local network for seamless operation. Proper electrical power wiring and communication cabling routing are essential to ensure reliability and maximize equipment lifespan.
Summary of Requirements
- Use designated (static) IP addresses/ Windows “Hosts” file/ avoid “daisy-chained” switches
- “Home Groups”/ workgroups/ Windows network names (use location or function for consistency)
- Wireless devices require an extra firewall; MAC address restrictions recommended
- IP security cameras must be on a separated network to avoid network bandwidth issues
Pre-Installation Requirements:
A. Dedicated Circuits:
- Supply all MicroSale equipment through dedicated grounded 120VAC, 15, or 20 Amp branch circuits.
- Each branch circuit must consist of four conductors: hot, neutral, isolated ground, and building ground (conduit).
- Recommend supplying the entire MicroSale system from the same phase.
- POS workstations require a dedicated duplex 120VAC outlet, while requisition printers need a simplex 120VAC outlet each.
- All MicroSale equipment must share a single low-impedance Isolated Ground (IG) for optimal network performance.
B. Communication Cable:
- Utilize Shielded Category 5 STP, 4 twisted pair cable for MicroSale's star communication network.
- Keep communication cable at least one foot away from AC wiring, fluorescent lighting, and five feet away from large transformers or motors.
- Cross AC wiring at a 90° angle if necessary.
- CAT 5 communications cabling system must adhere to the EIA/TIA 568B termination standard.
C. Electrical:
- Follow guidelines for appropriate electrical power wiring and communication cabling routing.
- PowerVar GroundGuard conditioners are certified alternatives for isolated/dedicated electrical wiring.
- Electricians must read the MicroSale Power and Wiring Guide before starting electrical work.
- MicroSale representative will guide the electrician on power requirements and provide assistance if needed.
II. Electrical Install:
A. Guidelines:
- MicroSale installations must conform to provided guidelines.
- MicroSale representative, in consultation with the site owner, will determine the location and number of required electrical outlets.
- Inspection by MicroSale after installation for required modifications or corrections.
B. Responsibilities:
-
Compliance with Regulations:
- Follow governmental regulations and applicable building codes for electrical system installation and safety.
-
Communication Cable:
- Ensure Category 5 certified routing for industry-standard Ethernet TCP/IP communications.
-
Uninterruptible Power Supply (UPS):
- Install a UPS if required by the site.
-
Unused Outlets:
- Disable or cover any unused outlets to prevent unauthorized plug-ins.
-
Workstation/Printer Branch Circuits:
- Each workstation/printer will have its own branch circuit conduits.
- A maximum of six branch circuit conduits may share a single 15/20 Amp breaker at the electrical sub-panel.
- No other equipment may share dedicated circuits.
-
Daisy Chaining (Exception):
- Daisy chaining of dedicated/isolated outlets is allowed for close proximity instances.
- Clearly identify and record all chained outlets in the "exception" area.
-
Maximum Distance for Daisy Chaining:
- The maximum distance from the first daisy-chained power receptacle to the last receptacle is 50 feet.
C. Grounding Specifications:
- All MicroSale equipment must share a single low-impedance Isolated Ground (IG) for optimal network performance.
- This IG ground must be common even for MicroSale equipment on separate 15/20 Amp (MicroSale dedicated) circuits.
Conclusion: Following these guidelines ensures a smooth MicroSale POS system installation, promoting reliability, and extending the lifespan of your equipment. Consult MicroSale support for any difficulties or questions during the implementation process.
