Installation: Waterrower OTF Generation 3 Rower Studio Power System Power Supply User Manual

Overview

The OTF Generation 3 Rower Studio Power System Power Supply is designed for studios using WATERROWER OTF Generation 3 Rowers. It converts building power into a shared low-voltage supply for multiple rowers, allowing an organized studio installation with up to 16 connected rower nodes.

The system is intended for fixed installation. It uses a wall-mounted power supply, junction boxes, color-coded wiring, raceway protection, and short DC cables to deliver power to each rower.

Detailed Description

The power supply accepts standard wall power at either 120 VAC or 220 VAC and converts it to 24 VDC. The DC output is distributed to individual rowers through a parallel studio wiring arrangement rather than powering each machine from a separate wall outlet.

Key components include the wall-mounted power supply, IEC power cord, DC output connection, smoked plastic protective enclosure, rower junction boxes, red and black DC conductors, metal raceway tracks, rubber raceway covers, junction box lids, and male-to-male DC cables.

The junction boxes form the connection points between the main supply and each rower. The metal and rubber raceways protect and conceal the wiring between boxes, while the short DC cables connect each junction box to the DC port beneath the corresponding rower’s forward riser.

Safety

• Disconnect and isolate the power supply from mains electricity before installation or maintenance.
• Mount the unit vertically with its power terminals facing downward.
• Use four screws to secure the power supply to the wall.
• Keep the smoked plastic enclosure installed around the power supply, with its open side facing downward.
• Match wiring by color: connect black conductors only to black conductors and red conductors only to red conductors.
• Tighten terminal connections securely, but do not overtighten junction box lid screws.
• Only energize the system after all rowers, junction boxes, and protective raceways have been installed and connected.

Setup and Operation

Mount the power supply

1. Choose a suitable wall location for the power supply.
2. Position the unit vertically, keeping the power terminals at the bottom.
3. Secure the unit with four screws through the mounting holes.

Connect the input power

1. Confirm that the red rocker switch is off.
2. Insert the power cord into the IEC port on the underside of the power supply.
3. Connect the other end of the cord to the wall outlet.

Connect the DC output

1. Insert the DC power cord into either DC OUT port. Either port can be used.
2. Install the smoked plastic enclosure over the power supply.
3. Use the enclosure’s outer holes as a guide when securing it to the wall.
4. Keep the enclosure’s open end facing downward.

Wire the rower network

1. Connect the DC leads from the power supply to the first rower’s junction box.
2. Attach the black supply wire to the terminal associated with the junction box lid’s black power wire.
3. Attach the red supply wire to the terminal associated with the lid’s red power wire.
4. Tighten both connections firmly.
5. Continue from one junction box to the next in a daisy-chain arrangement.
6. For each subsequent box, connect black wires to black wires and red wires to red wires.
7. At the final rower, connect the remaining wires according to the final-box arrangement.

Secure the junction boxes and raceways

1. Fasten each junction box to the rubber floor with the provided screws.
2. Center each box beneath the front portion of its rower.
3. Align the front edge of each box with the front edge of the rower’s front feet.
4. Lay the metal raceway sections neatly between the junction boxes.
5. If required, cut the metal raceway with an angle grinder or hacksaw.
6. Leave approximately a 1/2-inch gap between each raceway end and the junction box or its base.
7. Secure the metal raceway sections to the rubber floor using the provided screws.
8. Measure and cut the rubber raceway so it reaches into the recessed areas of the junction boxes.
9. Feed the inter-rower wires into the rubber raceway’s center cavity.
10. Press the rubber raceway into the angled lips of the metal track.
11. Install each junction box lid and tighten its screws without forcing them.

Connect each rower

1. Plug one end of a short male-to-male DC cable into the DC power port beneath the rower’s forward riser.
2. Plug the other end into the female jack on the cable emerging from the junction box lid.
3. Repeat the connection for every rower in the studio.

Turn on the system

1. Check that every rower and junction box is fully connected.
2. Turn on the red rocker switch at the power supply.
3. Confirm that the system status icon, shown as a gear or WATERROWER symbol, glows steady red.
4. Wait for each connected tablet to start, display the WATERROWER logo, and enter Standby mode.
5. Swipe the tablet screen to wake it and enter Ready mode.

Troubleshooting

• Power switch does not illuminate: Turn the rocker switch off, verify that the IEC cable is fully seated, and confirm that the wall outlet provides power before switching the system on again.
• Status icon is blinking red: A short circuit has been detected. Switch off and isolate the system from mains power before checking the red and black wiring, junction box terminals, DC cables, and rower connections.
• One rower does not start: Check the short DC cable at both ends, then inspect the related junction box for loose, reversed, or incomplete red and black connections.
• Several rowers do not start: Inspect the supply connection at the first junction box and the daisy-chain connection leading to the affected rowers.
• Wires remain visible after installation: Reposition or extend the rubber raceway so it reaches into the recessed junction box areas before reinstalling the lids.
• Raceway does not fit correctly: Confirm that the metal track is aligned and that approximately a 1/2-inch clearance remains at each junction box end.
• Tablets remain in Standby: Swipe each tablet screen to wake it and enter Ready mode.

Pros & Cons

• Pros: Supports up to 16 rowers, accepts 120 VAC or 220 VAC input, provides a centralized 24 VDC supply, and includes a protected wiring layout for studio installations.
• Cons: Installation requires wall mounting, junction box wiring, raceway fitting, careful polarity matching, and electrical isolation before maintenance.
