Intrinsically Safe Antenna Coupler
for use in Hazardous Areas
Installation & Operation Manual
OVERVIEW
The Solexy M series intrinsically safe antenna barrier is a
multichannel protection device that facilitates non-Ex
certified radio antenna installation in hazardous areas. The M
series features a barrier circuit which blocks power voltage in
the event of a radio transmitter/receiver fault. By limiting
transmitted power per local regulations and ensuring the
threshold power requirements for the area of installation are
met, the M series can easily be used with most passive
antennas. The M series protect the radio output signal using
a cable to connect to an antenna that is installed in a
hazardous area.
Note: The information in this manual is intended to assist
with equipment design and ensure proper installation.
READ THIS INSTRUCTION FIRST
To avoid serious or fatal personal injury or major property
damage, read and follow all safety instruction in this manual.
If you require additional assistance, please contact SOLEXY.

be installed and maintained according to suitable
standards for electrical application in potentially explosive
atmospheres (IEC/EN 60079-14, IEC/EN60079-17 and/or
other national standards).
▪Suitably trained personnel shall carry out installation
according to applicable code practice.
▪Read this first and keep this instruction manual always
available.
▪For proper installation, see the applicable control drawing
DDCD-0012 attached.

WARNINGS
1. Solexy M series shall only be installed in a non-hazardous
location (safe area or inside an approved enclosure, e.g.
Ex d, Ex t enclosure or Ex p panel)
2. Solexy M series antenna barrier must be connected to RF
source with a minimum internal impedance of 50Ω.
3. Connected antennas must be assessed, installed and
maintained according to suitable standards for electrical
application in potentially explosive atmospheres (e.g.
IEC/EN60079-0, IEC/EN60079-14, IEC/EN60079-17 or
other national standards).
4. Solexy M series antenna barrier does not provide any RF
power limitation. The threshold power must be limited by
the user to achieve the levels defined in IEC/EN60079-0
Table 5.
5. The user should not repair this equipment.
6. The user should not modify the unit.
7. The unit should not paint from the user.
8. If the equipment is likely to come in to contact with
aggressive substances, it is the responsibility of the user
to take suitable precautions that prevent it from being
adversely affected, thus ensuring that the type of
protection is not compromised. Aggressive substances:
example Acids, liquids, gases with can affected metals.
9. Maximum RF power input shall not exceed the value listed
into product specification paragraph below and control
drawing DDCD-0012.
10. The device can only be supplied by equipment rated for
max overvoltage category II.
11. The device must be installed following the earthing
requirements of IEC/EN 60079-14 using the ground
connection available on the device's housing.
INSTALLATION
For proper installation, see the applicable control drawing
DDCD-0012
1. If the lightning suppressor is used, connect to the output
side of the coupler.
2. Antenna and cable connections should be finger
tightened only. Over tightening can cause permanent
damage resulting in equipment failure.

This value does not consider any cable loss between the RF
transmitter and the M series and may therefore be
considered as the maximum allowable RF transmitter output
power when the M series is directly connected to an RF
transmitter.
Added cable loss between the RF transmitter and the M series
may allow the RF transmitter output power to exceed the
value above as long as the cable loss ensures the power at the
input of the M series is less than or equal to the above values.

It is permissible limited the maximum power output of the
transmitter by a programmable or software setting but it
must not be possible for an end-user to override it.
MAXIMUM PERMITTED
RF THRESHOLD POWER (Pth)
The RF threshold power, sometimes called the effective
isotropic radiated power (EIRP), as defined in IEC/EN60079-0,
is the product of the effective output power of a radio
transmitter multiplied by the power gain of a connected
antenna. The maximum threshold powers for each
equipment group as defined by Table 5 in IEC/EN60079-0 are
provided above.
Because most antennas list the gain relative to an isotropic
radiator (dBi) instead of the raw power gain, it is often easier
to simply add the antenna gain in dBi to the radio output
power in decibel-milliwatts (dBm). Any added cable loss
between the RF transmitter output and the M series input, or
the M series output and the antenna may also be factored in.

▪The resulting threshold power calculated by the above
formula MUST be below the threshold power for the
operating area group rating given above.
▪Consideration of fault conditions in the radio transmitter
is not necessary. The max radio transmitter’s RF power
output should be taken from the manufacturer’s
datasheet in normal operation.
▪A radio output power lower than those provided above
may be used to allow for an antenna with a higher gain.
▪In case of a device with multiple outputs and multiple
antennas, each threshold power is calculated separately
for each output/antenna.
▪Gain of multiband antennas should be evaluated
separately at each frequency.
▪High gain directional antennas on the same device should
not be directed in the same direction.
