The TP-P Series surge protector provides surge protection for field mounted process transmitters and is available
for 1/2’’NPT, 20mm ISO and G1/2” threaded conduit entries. The TP-P Series is certified and approved for use in
hazardous areas. More details of this are shown throughout this installation guide.

3 3..1 1 Disconnect and isolate existing circuit.
Select conduit entry to be used for installa-
tion, and remove any blanking plug. Note:
If direct installation onto the apparatus itself
is impossible e.g. because all conduit entries
are in use already, an external junction box
or conduit hub can be used. The TP-P Series
s supplied with 300mm leads, which should
be sufficient for them to reach the transmit-
ter terminals from a junction box. If these
leads are not long enough then use supple-
mentary terminals and wiring. Installation
should be within 1m of, and bonded to, the
transmitter.
3 3..2 2 Ensure that the TP-P body thread matches
the conduit entry. Thread types are not interchangeable, but adapters may be used where necessary.
For explosionproof (EEx d) installations, only certified or approved adapters are permitted.
3 3..3 3 Remove apparatus terminal housing cover.
3 3..4 4 Insert connecting wires into apparatus body and start threading unit into conduit entry using moderate
hand-force, with lubricants as necessary.
3 3..5 5 Tighten fully (hand-tight plus 1/2 turn of 23mm A/F spanner). The steel body of the TP-P device is not
used as part of the electrical circuit, therefore sealing of the thread with PTFE tape or other sealing com
pounds will not affect the performance of the TP-P device.
N No otte e:: In Explosionproof (EEx d) applications, sealing of the thread is not permitted – the TP-P should be treated in
the same way as any other cable gland/hub into similar equipment.
3 3..6 6 For effective protection, the leads of the TP-P should be as short as possible. Before wiring to the trans-
mitter terminals, cut the leads to the appropriate length and strip back 10mm of insulation. Do not try
to coil excess lengths of cable into the transmitter housing as this will degrade the protection given by
the surge protector.
3 3..7 7 Connect the flying leads to the terminals indicated below;-
N No otte e:: The protection circuit needs to be connected in series with the transmitter 4-20mA current loop.

3 3..8 8 Ensure that all connections are tight, particularly the earth bonding connection, which is likely to be
via a stud within the apparatus terminal housing.
3 3..9 9 Refit apparatus terminal housing cover.
3 3..1 10 0 The field wiring is next connected to the provided three position plug. Cve to the terminal
marked “+”, Connect –ve to the terminal marked “-“, and connect the ground wire or shield (if present)
to the terminal marked “G”. Wire strip length is 5mm (0.196”).
3 3..1 11 1 Using a long nose pliers, insert the plug into the socket inside the TP-P body. This connector must be
orientated correctly for full seating and connectivity.
3 3..1 12 2 Complete the installation by mounting an appropriate fitting and/or conduit for the location used.
3 3..1 13 3 Reconnect circuit and test system to verify operational status.

The TP-P earth wire (Green/Yellow) should be connected to the earth terminal or stud usually provided inside
the transmitter housing. In the unlikely event that no such stud exists, make the connection to a structural
mounting part, such as a terminal block fixing screw.

At intervals of not more than one year (more frequently for particularly harsh environments) visually check the
installation and ensure that:
i) Device and/or enclosure is firmly attached to mounting
ii) There are no signs of external damage or corrosion
iii) Interconnecting cables are not frayed or otherwise damaged
iv) All connections are properly made with clear labelling
If this unit suffers damage send back to MTL Surge Technologies for evaluation which should only be carried
out by MTL Surge Technologies. This product is not field repairable.

In hazardous locations check the marking on the device to ensure that it is appropriate for the application. Mark
the appropriate box (figure 2) to indicate the type of protection being utilised. For marking use a punch mark.
The product range has been designed to meet the fault tolerant requirements of Electrical Apparatus for
Category ‘ia’. Entity parameters: See Certificate number Baseefa06ATEX0034X

The following relate to installations to Baseefa06ATEX0034X:
1. The apparatus is to be installed such that the flying leads are afforded a degree of protection of at least
IP54.
2. Although all versions of the TP-P Series Surge Protection Devices meet the 500V test to the metal case
the electrical circuit within the Surge Protection Devices are not capable of withstanding the 500V voltage
withstand test for one minute without breakdown to the Green/Yellow wire. This must be taken into con-
sideration in any installation.
3. These devices are not provided with an external connection facility for an earthing or bonding conductor. It
is the user’s responsibility to ensure adequate earth continuity via the mounting arrangement.
4. This apparatus is also afforded Flameproof Certification to Baseefa06ATEX0035X and is dual marked. It
is the user’s responsibility to determine the relevant protection concept and to permanently mark the
