Console DTU (Data Transfer Unit) Installation Instructions Overview The TS-DTU will be installed in the dispenser when it is used as a Remote DTU or inside the building when used as a Console DTU. These installation instructions are to be used for installing the TS-DTU inside the building. When used as a Console DTU, data is received from the Remote DTU units via power line communication. The data is then sent to the System Console (TS-550 / 5000 / EMS) for processing. Unlike the Remote DTU units, the Console DTU will have no Intrinsically safe sensors connected to it. Site Inspection A licensed electrician should perform a site inspection before installing any equipment. The Console DTU must be connected to all electrical phases that supply power to dispensers containing Remote DTUs. Check for any electrical isolation. Isolation between the electrical panel and the dispenser can result in poor or no communication with the DTU. Make sure there is not a power conditioner between the Console DTU and dispenser power. Installation Procedure Tools and Supplies Needed • 1/2 " Cord grip / strain relief • Small slotted screwdriver • Multimeter • Mounting screws • 2 - wire shielded cable • 14 AWG wire (one for each phase and ground) Step 1 – Remove System Power Remove power from the TS-5XXX Series System Console and do NOT return power to the System Console or to the Console DTU until instructed to do so. Electrical Hazard! Always disconnect power supplies before installing or servicing the console TS-DTU. Use proper lock-out and tag-out procedures to ensure no power is accidentally applied to the system. Failure to do so could result in severe injury or death. Step 2 – Mounting the Console DTU Mount the Console DTU as close to the circuit breaker panel that is suppling the dispenser(s). Remove the cover and insert a screw (not supplied) into each of the four corners of the enclosure. Mount the unit to the wall. You may optionally use the supplied mounting brackets. Step 3 – Power Connection The Console DTU may use the same circuit breaker as the System Console but DO NOT connect the power for the Console DTU inside the Console enclosure. Install a junction box or wire the Console directly to the circuit breaker panel. Ideally, the circuit selected for the console power will be on the same phase as all dispensers and no further power connections will be required. If any dispensers are on a different phase, run wires from the L2 and L3 connections on the Console DTU to the appropriate circuit breakers for the required extra phases. If there is any question about what phase some of the dispensers are on, it is recommended to connect all three phases to the Console DTU. Connect the neutral for the Console DTU to the same neutral supplying the dispensers. If there is not a clean neutral return for the DTU then poor quality may result. Warning: Cycling power to the Console DTU without powering off the System Console will cause the System Console to reboot. Installer must use conduit for connecting the DTU on the power connection side. Ground L3 L2 Neutral L1 Figure 1: Power Connections to the Console DTU 1 Step 4 – Bus Termination Jumper Removal The Console DTU will provide system bus termination when installed and running. Therefore the system bus termination currently provided by the Power Supply Module needs to be removed. Refer to the TS-5XXX Series Installation Guide for instructions on how to remove a module. Be extremely careful when removing the power supply module so it does not rub against any other part of the system. After it is removed from the system, locate the system bus termination jumper JP1 and remove it (Figure 2).

Step 5 – Data Connection The Console DTU acts as an external System Console module and therefore must be connected to the system bus. This is made possible via the external BUS EXT connection, located on the power supply module. The bus connection requires 2-wire shielded cable and FFS recommends Belden 87761. On the Console DTU, the cable enters through the Intrinsically Safe (I.S.) opening but is connected outside of the I.S. area, which is not used in the Console DTU. Therefore the I.S. shield will need to be removed and discarded. Secure the bus cable on the Console DTU side using a cord grip. On the System Console communications bracket, locate the BUS EXT connector (Figure 4). The connector is removable for convenient wiring. Refer to the following table and make the proper BUS (HIGH, LOW, GND) connections (Figure 3). To make the necessary connections between the System Console and the DTU, plug the BUS EXT connector back into the System Console. Secure the bus cable so it is not accidentally disconnected.

Finally replace the Console DTU Cover. Step 7 – Power Up Return power to the System Console and the newly installed Console DTU.
