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.
