Standard for Electrical Installations, Section 32
NFPA 70, and the National Fire Alarm and signaling Code,
NFPA 72
The installation of the units must also be in accordance with
any local codes that may apply and should only be carried
out by a competent electrical engineer who has the
necessary training.
2.2 Ingress Protection Ratings
The product is rated for ingress Protection as follows:
IP rating per EN60529: IP66
Type rating per UL50E / NEMA250: 4 / 4X / 3R / 13
Suitable for exposure to Acetone , Ammonium Hydroxide ,
Diethyl Ether , Ethyl Acetate , Ethylene Dichloride , Furfural,
n-hexane , Methyl Ethyl Ketone , Methanol , 2-NitroPropane
and Toluene.
To maintain the ingress protection rating, the cable entries
must be fitted with suitably rated, certified cable entry and/or
blanking devices during installation.
2.3 Electrical Ratings
It is important that a suitable power supply is used to run the
equipment. The power supply selected must have the
necessary capacity to provide the input current to all the units.
The input current will vary according to the voltage input level.
3) Special Conditions of Use
The enclosure coating is non-conductive and may generate an
ignition-capable level of electrostatic charges under certain
extreme conditions. The user should ensure that the
equipment is not installed in a location where it may be
subjected to external conditions (such as high pressure steam)
which might cause a buildup of electrostatic charges on non-
conducting surfaces. Additionally, cleaning of the equipment
should be done only with a damp cloth.

4) Installation
There are no restrictions on unit orientation.
4.1 Safe Installation Requirements
To maintain the ingress protection rating and mode of
protection, the cable entries must be fitted with suitably
certified cable entry and/or blanking devices during
installation. If conduit is used for installation, seal conduit
within 18 inches from the enclosure.
If entries are fitted with adaptors they must be suitably certified
for the application. Fitting of blanking elements into adaptors
is not permitted.
Check that the ‘O’ ring seal is in place before replacing the
explosionproof cover.
5) Location and Mounting
The Junction Box should only be fixed to services that can
carry the weight of the unit.
The D1xJ2X Junction box can be mounted using one of three
methods.
1. The Junction Box can be surface mounted by removing,
rotating and reinstalling the stowed mounting lugs. These
are suitable for 6mm diameter fixings.
a. Remove 2 x M5 fasteners per
mounting lug
b. Reverse and rotate lug and
reseat onto enclosure
c. Secure lug using the 2 x M5
Fasteners
2. Alternatively the Junction Box can be conduit mounted
using the ¾”NPT entry on the base of the unit.
3. Additionally, the Junction Box can be mounted using the
ratchet adjustable stainless-steel wall bracket assembly.
This is available as an accessory – part code: SP77-0001.
Dimensions in mm[in.]
Fig. 1 Fixing Location for Junction Box
6) Access to the Enclosure
In order to connect the electrical supply cables to the junction
box, it is necessary to open the explosion proof enclosure.
Loosen the locking grub screw in the junction box cover and
then remove the lid to gain access to the chamber. This can
be achieved by unscrewing the cover, taking extreme care
not to damage the threads when doing so.
Fig. 2 Accessing the Enclosure.
On completion of the installation the flameproof threads should
be inspected to ensure that they are clean and that they have
not been damaged during installation. Ensure the O-ring seal
is in place and undamaged.
When fitting the flameproof cover ensure the thread is
engaged correctly. Fully tighten the cover all the way, ensure
no gap is visible between the cover and base of the enclosure.
7) Selection of Cable, Cable Glands, Blanking
Elements & Adapters
When selecting the cable size, consideration must be given to
the input current that each unit is carrying (see section 2.3).
The cable size selected must have the necessary capacity to
provide the input current to all of the units connected to the
line.
The entries are 2-off M20 x 1.5 thread & 5-off ¾” NPT thread
If a high IP (Ingress Protection) rating is required then a
suitable sealing washer must be fitted under the cable glands
or blanking plugs.
For use in explosive dust atmospheres, a minimum ingress
protection rating of IP6X must be maintained.
For use in explosive gas atmospheres, a minimum ingress
protection rating of IP54 must be maintained.

NPT plugs should be greased before insertion.
For high ambient temperatures the cable entry temperature
or the cable branching point temperature may exceed 60ºC
and therefore suitable heat resisting cables and cable glands
must be used, with a rated service temperature of at least the

8) Cable Connections
The units have 2-off M20 x 1.5 threaded entries and 5-off ¾”
NPT x 14 threaded entries.
Electrical connections are to be made into the terminal blocks
or DIN-rail mounted inside the junction box enclosure. See
section 5 of this manual for access to the enclosure.
Wires having a cross sectional area between 0.5 mm² to
2.5mm² can be connected to each terminal way. If fitting 2-off
wires to one terminal way the sum of the 2-off wires must be a
maximum cross sectional area of 2.5mm². For Terminals strip
wires to 5mm, for DIN rails strip to 8mm. Wires may also be
fitted using ferrules. Terminal screws need to be tightened
down with a tightening torque of 0.4Nm / 3.5lb-in and DIN rails
screws to 0.56 Nm / 5 Lb-in. When connecting wires to any
terminals great care should be taken to dress the wires so that
when the cover is inserted into the chamber the wires do not
exert excess pressure on the terminal blocks. This is
particularly important when using cables with large cross
sectional areas such as 2.5mm².
9) Variants
The D1xJ2 Junction boxes are available pre-fitted with 12-way
terminal (Fig. 3a) or DIN Rail (Fig. 3b) connections. A
D1xJ2M01 custom module variant is also available, please
refer to the website for further info.
Fig. 3a – D2xJ2T01 12-way terminal block variant.
Fig. 3b – D2xJ2D01 12-way DIN Rail variant.
10) Earthing
The unit has an external and an internal earth terminal, (please
see fig 4).
Internal earthing connections should be made to the internal
Earth terminal in the base of the housing using a ring crimped
terminal to secure the earth conductor under the earth clamp.
The earth conductor should be at least equal in size and rating
to the incoming power conductors.
External earthing connections should be made to the M5 earth
stud, using a ring crimp terminal to secure the earth conductor
to the earth stud. The external earth conductor should be at
least 4mm2 in size.
