1. Preparation
Danger:
Electrical shock or burn hazard. Qualified
personnel should only install this product. Failure to lockout
electrical power during installation or maintenance can
result in fatal electrocution or severe burns. Before making
any connections to this electrical panel please ensure that
power has been removed from all associated wiring,
electrical panels, and other electrical equipment.
Caution Notes:
1. The installation of this Transient Discriminating Surge
Diverter (TDS) should follow all applicable national electrical
codes.
2. Check to ensure that the power frequency line voltage
does not exceed the maximum continuous operating
voltage (Uc) of the TDS.
3. Prior to installation, ensure that the TDS is of the correct
voltage, current, and frequency.
4. The ground (earth) terminal must be connected to a low
impedance earth (<10 ohms) for correct operation.
5. Do not perform a “Flash Test” or use a Megger to test
circuits that are protected with these TDS units. This may
damage the TDS(s) and affect the insulation readings being
performed.
6. Follow all instructions to ensure correct and safe
operation and observe nationally recognized codes of
authorities having jurisdiction.
7. Do not attempt to open or tamper with the TDS unit in
any way as this may compromise performance and will void
warranty.
2. Introduction
The Transient Discriminating Surge Diverter (TDS) series has
been designed to provide one mode of protection to single-phase
power distribution systems (TDS150 or TDS1100), multi-modes in
a split phase distribution system (TDS50) or in a three-phase
distribution system (TDS350).
Units can be connected (L-N), (L-G) or (N-G) depending on the
type of power distribution system.
Multiple TDS units can be used to provide multi-modes of
protection or to protect three-phase distribution systems.
TDS units are available with maximum continuous operating
voltages (Uc) of: 170V, 275V, 320V and 610V for the protection of
distribution systems with nominal RMS voltages of 120Vac,
220Vac, 240Vac and 480Vac, respectively. TDS units may also be
used to protect DC power systems - ref. Table 1.
3. Quick Installation Overview
Please follow the sequence indicated:
1. First, ensure that power is removed from the area and the
circuits to be connected.
2. Install earth leakage protection (RCD) if appropriate or where
required by national codes and authorities having jurisdiction.
Note: When connecting surge protection L-G it is preferable to
install the device before the RCD to avoid “nuisance tripping”
which may occur when the SPD operates.
3. Connect wiring to the two primary terminals indicated.
4. Connect the alarm terminals if remote monitoring is required.
5. Apply power and observe correct operation of the TDS and
status indication is not tripped.
4. Mounting
TDS’s are designed to clip to 35mm (top hat) DIN rails (standard
EN50022) set in the horizontal position with the TDS securing clips
towards the bottom of the rail and the label text facing the correct
way up.
Note:
TDS modules must be installed in an enclosure or switch
board panel in such a way that :
DANGER
ELECTRICAL SHOCK OR BURN HAZARD. HAZARDOUS VOLTAGES EXIST INTERNAL TO THE TDS. THIS UNIT SHOULD BE INSTALLED AND SERVICED ONLY BY
QUALIFIED PERSONNEL IN CONFORMANCE WITH ALL GOVERNING CODES AND INSTRUCTIONS. FAILURE TO LOCKOUT ELECTRICAL POWER DURING INSTALLATION
OR MAINTENANCE CAN RESULT IN FATAL ELECTROCUTION, SEVERE BURNS, OR OTHER INJURIES. BEFORE WORKING WITH OR MAKING ANY CONNECTIONS TO THIS
DEVICE, BE SURE THAT POWER HAS BEEN REMOVED FROM ALL ASSOCIATED WIRING, ELECTRICAL PANELS, AND OTHER ELECTRICAL EQUIPMENT.
1. The power supply to the TDS should always be turned (and locked) OFF before the unit is accessed for any reason.
2. Prior to installation, ensure that the TDS is of the correct voltage, current, phasing, and frequency for the applicable rating of the power distribution system.
3. This unit must be installed on the load side of the main over-current protection.
