This section provides alternate methods of supplying AC power to the MICROS POS System.
When providing the Preferred AC Power System is cost prohibitive and/or would require major structural changes, we have defined a relaxed AC Power System based on Oracle MICROS Approved Power Conditioners. However, the Preferred AC Power System is recommended by Oracle MICROS.
The Relaxed/Power Conditioned AC Power System is described as follows:
MICROS-approved Power Conditioners are required at all MICROS equipment locations.
MICROS-approved Uninterruptable Power Conditioners (UPC) are required at each server.
Ensure all MICROS AC Power branch circuits originate from the same Non-Dedicated Power Panel. Ensure this Panel is equipped with an isolated ground bus that is electrically isolated from the panel frame. Install an insulated equipment grounding conductor (sized the same as the supply conductors) in the same conduit as the supply conductors from the main or source power panel. Terminate the equipment grounding conductor on the ground bus in the main or source panel and on the isolated ground bus in the Non-Dedicated Power Panel.
Do not select the Power Panel supplying heavy equipment within the facility as the Non-Dedicated Power Panel supplying the MICROS equipment.
Dedicate all MICROS AC Power Circuits for MICROS equipment. Do not use these circuits to supply any equipment other than MICROS equipment.
Install all MICROS AC Power Circuits in a dedicated conduit system. This dedicated conduit system cannot contain circuits other than MICROS circuits. Ensure the conduit used for the MICROS AC Power Circuits is ferrous metallic. Flexible, rigid, or greenfield-metallic conduit is acceptable. Aluminum conduit is not acceptable.
For each dedicated MICROS AC Power circuit, include a full size (same as supply conductors) insulated equipment grounding conductor installed within the same dedicated conduit system as the supply conductors. Terminate this ground conductor at the isolated ground bus in the Non-Dedicated Power Panel and on the grounding terminal of each Isolated Ground AC Power Receptacle.
Ensure all AC Power Receptacles are the isolating ground type. Install according to the specifications in the AC Power Receptacles Grounding section.
When choosing a base, mid-level, or premium Power Conditioning system, an upgrade to the next level is required if problems occur (e.g. power problems generated by the power company or other equipment in the building).
This method is an acceptable alternative when the Preferred or Relaxed/ Power Conditioned AC Power System is cost prohibitive and/or would require major structural changes. However, the Preferred AC Power System is recommended by MICROS.
The Power Conditioned AC Power System is described as follows:
MICROS-approved AC Power Conditioners are required at all MICROS equipment locations.
MICROS-approved Uninterruptable Power Conditioners (UPC) are required at each server.
Whenever possible, all MICROS equipment should be installed on the same sub panel. However, MICROS equipment can be supplied by different non-dedicated AC power sub panels, but the sub panels should be supplied by the same main or source panel. If multiple main or source panels are utilized, ground potential problems could arise and severely degrade the performance of the system, even if AC power conditioners are used. Line Drivers or Optical Isolation Devices may be required on selected data transmission cable runs to eliminate the effects of ground potential problems.
Whenever possible, any Power Panel supplying heavy equipment within the facility should not be selected as the power panel supplying MICROS AC Power Circuits. Equipment problems resulting from utilizing a Power Panel supplying heavy equipment will be reviewed on an individual basis.
When choosing a base, mid-level, or premium Power Conditioning system, an upgrade to the next level may be required if problems arise. This could be due to power problems generated by the power company or other equipment in the building.
