INSTRUCTION SHEET
DANGER
ELECTRICAL SHOCK OR BURN HAZARD. HAZARDOUS VOLTAGES EXIST INTERNAL TO THE TDX. 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 TDX should always be turned (and locked) OFF before the unit is accessed for any reason.
2. Prior to installation, ensure that the TDX 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.
4. Diagrams are for reference only. Schematics are representative of typical applications and are only to be used for reference.
WARNING
1. ERICO products shall be installed and used only as indicated in ERICO product instruction sheets and training materials. Instruction sheets are available at
www.erico.com
and from your ERICO customer service representative.
2. ERICO products must never be used for a purpose other than the purpose for which they were designed or in a manner that exceeds specified load ratings.
3. All instructions must be completely followed to ensure proper and safe installation and performance.
4. Improper installation, misuse, misapplication or other failure to completely follow ERICO’s instructions and warnings may cause product malfunction, property damage, serious bodily injury and death.
SAFETY INSTRUCTIONS: All governing codes and regulations and those required by the job site must be observed. Always use appropriate safety equipment such as eye protection, hard hat, and gloves as appropriate to the application.

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 :

TDS150-1SR-xxx
TDS1100-1SR-xxx
TDS350-xxx-xxx
TDS50 120/240
