PourMyBeer Tap Wall Power Diagram

*Example only, your project manager will detail specific power system requirements for your location.

Power / Electrical Requirements

  • 110V outlet, Uninterrupted Power Supply (UPS), 24V transformer, screen,
  • Power daisy-chain (4tap maximum per transformer.)
  • When designing your tap wall, space for the UPS and transformers must be considered.
  • Transformers must be within 6 feet of screens without having to run extra cable to extend the power feed.
  • There must also be a clear route to feed power cables and daisy-chain power between screens. 
  • Depending on the number of taps, we will need 1-5 outlets on a dedicated 15A circuit. Please, confirm this with your project manager.
  • Power will go from the 110v outlet, Backup Battery, 24v transformers, screens. 
  • For Direct Draw Systems, or systems where the cooler is directly behind the tapwall, the simplest way to provide power and network access is to locate it all on top of the cooler. This way the power leads and network cables can be dropped down directly to the screens. The Network Switch and UPS Battery backups will all be on top of the cooler if built like this.

Power Checklist

The PourMyBeer system needs power at the following locations:

One 110V outlet for each UPS (1-5 total).
Either on top of the walk-in cooler or in a cabinet near the tap wall without having to run extra wire. 

Check-In Station(s)
One 110V outlet for each check-in station.
These are located at the front entrance or traditional bar area. Usually located
near a POS station. Each one of these will also require an RJ45 terminated cat6 going back to the provided network switch. 

PourMyBeer Server
2 110V outlets (1 for the computer monitor, 1 for the tower).

The provided server needs an RJ45 terminated cat6 run to the provided network switch. 

It will also need a hardwired internet connection. 
These must be in place before PourMyBeer installation can be booked.
This is usually in the office or data closet.


Equipment Specs

Uninterrupted Power Supply (UPS) Battery Backup

Included with your system are Uninterrupted Power Supply (UPS) unit(s) for the tap wall, the server and your charger. By having a UPS in place, your Beer Wall can operate as a stand-alone system and will be protected from power surges. These Units have 5 surge and battery protected outlets.

We can power up to 20 Taps with 1 UPS unit.
