DSD INSTALLATION INSTRUCTIONS
1. WARNINGS
• Prior to installation ensure that the unit is
of the correct voltage and frequency, and is
the type recommended for the local power
distribution, and for the equipment being
protected.
• Hazardous voltages may exist internally to
the modules. The units should be installed
(and replaced) only by qualified personnel
in accordance with all relevant Electricity
Safety Standards.
• Do not power three phase connected units
without the upstream neutral connected.
Failure to do so may damage the units and/
or the load.
• Where the unit has an earth terminal, this
must be connected to a low impedance earth
(<10 Ω) for correct operation.
PAGE 4
• If connecting to the TDS Opto-coupler
alarm outputs do not reverse the +/connections or exceed the maximum
permissible ratings as damage may occur.
• Use only the TDS-AR Alarm Relay with
TDS-DINLINE.
• Use only TDS-SC Surge Counter with TDS
DINLINE.
• Units must be installed in an enclosure or
panel, ensure this does not cause the units
environmental ratings to be exceeded.
• Do not “Megger” or “Flash Test” circuits
with TDS-DINLINE units installed.
• All instructions must be followed to ensure
correct and safe operation.
• Diagrams are illustrative only, and should
not be relied on in isolation.
2. INTRODUCTION
This Installation Manual details the preferred
procedure for the installation of TDSDINLINE™ SURGE SUPPRESSORS and
options.
The TDS-DINLINE SURGE SUPPRESSORS
are available in a variety of surge ratings,
which are packaged in the 2M, 4M and 8M
“DIN 43 880” compliant enclosures. They are
designed to suit many distribution systems
including TN-C, TN-S, TN-C-S (MEN) and TT.
They can be selected for use with distribution
systems with nominal RMS voltages of 110/
120, 220/230/240V or 277V at frequencies of
50/60 Hz.
Recommended installation and connection of
the ALARM RELAY (TDS-AR) is detailed in
Section 14. Installation and connection of the
Surge Counter (TDS-SC) is detailed in section
15.
3. QUICK INSTALLATION GUIDE
Install in the following manner:
1. Ensure that power is removed from the area
and circuits to be connected.
2. Install the DIN mounting rail, if not fitted.
3. Snap lock the Surge Suppressor to the rail.
4. Connect wiring to the indicated terminals.
5. Ensure compliance with supplied
instructions.
6. Apply power and observe correct operation
of Status Indicators, and alarm facilities if
utilised.

4. PROTECTION CONCEPTS
To optimise effectiveness of installed
protection a concept of “Unprotected” and
“Protected” wiring should be followed. Wiring
from the transient source to the Surge
Suppressor should be considered
“Unprotected” and kept remote from all other
wiring (approximately 300mm) where possible.
Wiring on the equipment side of the Surge
Suppressor should be considered “Protected”.
The separation of “Protected” from
“Unprotected” wiring is recommended in order
to minimise the risk of transients conducted on
“Unprotected” wiring cross coupling on to
“Protected” circuits, thus compromising the
level of protection available from the Surge
Suppressor.

Keep other cables and
equipment away
from this area.

5. MOUNTING
Surge Suppressors are designed to clip to
35mm top hat DIN rails (to Standard
EN50022). Unless otherwise mechanically
restrained, use horizontal DIN rails with the
Surge Suppressor fixing clip to the bottom, ie
label text the correct way up.
Units must be installed in an enclosure or
panel to provide the appropriate degree of
electrical and environmental protection.

Only use enclosures that:
• Do not cause the internal temperature to
exceed 55 deg C.
• Provide adequate electrical and safety

protection.
• Prevent the ingress of moisture and water.
• Allow Surge Suppressor Status Indication
to be inspected.

6. VOLTAGE RATINGS
Ensure that the correct voltage rating unit is
installed. Exceeding the nominal voltage
rating under transient conditions may affect
product life. Do not exceed the Maximum
Permissible Abnormal Over Voltage rating.
Model Nominal Voltage Permissible
TDS XXX-120 110-120 Vac 240Vac
TDS XXX-208 208 Vac 260 Vac
TDS XXX-240 220-240 Vac 415 Vac
TDS XXX-277 220-277 Vac 480 Vac

7. PROTECTION MODES
Protection Modes refers to how the internal
protection is arranged and applied to the
circuit to be protected.
TDS-DINLINE Surge Suppressors are Single
Mode units which provide protection between
two conductors connected to the terminals
marked T1 and T2. These units can be
connected to provide protection from PhaseNeutral* or Phase-Earth* or Neutral-Earth.
To allow the status indication and alarm
circuitry to operate, a neutral connection is
required for Phase-Earth* configured units,
and a Phase* connection is required for
Neutral-Earth configured units.
* Note. Some users may be used to the
terminology “Active” or “Line”, in place of
“Phase”. For consistency “Phase” is used
throughout this documentation.

DSD INSTALLATION INSTRUCTIONS
Phase to Phase protection can also be provided
by Surge Suppressors, provided that the
nominal and maximum voltage ratings are not
exceeded.
8. CONDUCTOR SIZES
Each Surge Suppressor terminal is designed
to accept wire sizes from 1.5mm2 to 6mm2,
solid or stranded conductor. Insulation should
be stripped back 8mm before terminating into
the tunnel terminal.
Where two conductors require termination in
the same tunnel terminal, conductors should
be limited to a maximum size of 4mm2.
Do not use excessive force when tightening the
terminal.
