1. PREPARATION
DANGER: Electrical shock or burn hazard.
Installation of this Transient Voltage Surge
Suppressor should only be made by qualified
personnel. 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 be sure that power
has been removed from all associated wiring, electrical
panels, and other electrical equipment.
CAUTION NOTES:
1. The installation of this Surge Protector should
follow all applicable electrical codes, such as the
National Electrical Code, or the Canadian Electrical
Code.
2. Check to make sure line voltage does not exceed
Surge Protector voltage requirement.
3. Prior to installation ensure that the TDS is of the
correct voltage, current, and frequency rating for
your application.
4. The 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 Mega-Ohm
Meter (Megger) to test circuits that are protected
with TDS modules. Damage may occur to the TDS
modules.
6. Follow all instructions to ensure correct and safe
operation. All installations should observe the
requirements of the National Electrical Code,
Canadian Electric Code and/or applicable local
codes
7. Do not attempt to open or tamper with the TDS units
in any way as this may compromise performance
and will void warranty.
2. INTRODUCTION
Transient Discriminating Suppressors (TDS) can be selected
for use on single phase distribution systems of nominal RMS
voltages 120V, 240V (2W+G) or 120/240V (3W+G). Multiple
units can be used to protect other power distribution systems.
The 120Vac unit also operates on nominal 125Vdc supplies.
3. QUICK INSTALLATION OVERVIEW
Install in the following manner:
1. Ensure that power is removed from the area and the
circuits that will be connected.
2. Snap lock the TDS module to the DIN rail.
3. Install overcurrent protection if appropriate.
4. Connect wiring to the indicated L, N & E and (if used)
alarm terminals.
5. Apply power and observe correct operation of the Status
Indication, and alarm connections.
4. MOUNTING
TDSs are designed to clip to 35mm (top hat) DIN rails
(standard EN50022). Unless otherwise mechanically
restrained, use horizontal DIN rails with the TDS module spring
clips to the bottom and the label text the correct way up.
NOTE: TDS modules must be installed in an enclosure or
panel that:
• prevents the TDS unit temperature from exceeding
122°F (50°C)
• provides adequate electrical and safety protection
• prevents the ingress of moisture and water
• allows TDS status indicators to be inspected
5. ELECTRICAL CONNECTION
The interconnecting wiring should:
•
be of size #10 to #14 AWG (2.5mm² to 6mm²) solid or
stranded conductor. The wire insulation should be
stripped back 5/16" (8mm). NOTE: Do not use greater
than 9inlbs (1Nm) of torque when tightening the terminals.
For UL compliance where two wires may need to be
terminated into one terminal, the permissible wire size is
18AWG each
•
be as short as possible (preferably not exceeding 12
inches (300mm)
•
avoid sharp bends (ideally 4 inch (100mm) radius
recommended)
•
have the conductors twisted together where possible
