1. Introduction
This manual describes the MGG electric fence energizer model :
MGG EF-SRS6-S250
2. Important safety introduction
WARNING: Please read all instructions
⚫Do not touch a live fence
⚫Do not drench with water.
⚫This product is for use in controlling livestock. Any other use is
prohibited.
⚫Keep fence clear of weeds, branches etc to avoid electrical shorts resulting
in battery drainage.
⚫Do not climb over, through or under a multi -wire electric fence. Use a gate
or a specially designed crossing point.
⚫Do NOT become entangled in the fence. Avoid electric fence constructions
that are likely to lead to the entanglement of animals or persons.
⚫Electric animal fences shall be installed and operated so that they cause
no electrical hazard to persons, animals or their surroundings.
⚫It is recommended that in all areas where there is a likely presence of
unsupervised children who will be unaware of the dangers of electric
fencing, that a suitably rated current limiting device having a resistance of
4
not less than 500 ohms be connected between the energizer and the
electric fence in this area.
⚫The appliance is not intended for use by young children or infirm persons
without supervision.
⚫Do not place combustible materials near the fence or energizer
connections. In times of extreme fire risk, disconnect energizer.
⚫Don't dismantle. Don't make any changes to this energizer. Don't touch
high voltage parts which can cause electric shock. This energizer is not
user-servicable.
⚫Young children should be supervised to ensure that they do not play with
the appliance.
⚫An electric animal fence shall not be supplied from two separate
energizers or from independent fence circuits of the same energizer. That
is very dangerous.
⚫For any two separate electric fences, each supplied from a separate
energizer independently timed, the distance between the wires of the two
electric animal fences shall be at least 2.5m.
⚫Barbed wire or razor wire must not be electrified by an energizer.
⚫A non-electrified fence incorporating barbed wire or razor wire may be
used to support one or more off-set electrified wires of an electric animal
fence. The supporting devices for the electrified wires shall be constructed
so as to ensure that these wires are positioned at a minimum distance of
150 mm from the vertical plane of the non-electrified wires. The barbed
wire and razor wire shall be earthed at regular intervals.
⚫Where an electric animal fence crosses a public pathway, a non-electrified
gate shall be incorporated in the electric fence at that point or a crossing by
means of stiles. At any such crossing the adjacent electrified wires must
carry warning signs.
⚫In areas of public access, use an electric fence warning sign every 10m
(33ft) to identify the electrified wire(s).
⚫Crossing with overhead power lines should be avoided wherever possible.
If such a crossing cannot be avoided, it should be made underneath the
power line and as nearly as possible at right angles to the power line.
⚫If connecting leads and electric fence wires are installed near an over head
power line, the clearances should be not less than those shown below:
Power Line Voltage
V
Clearance
M
≤1000
＞1000 ≤33000
＞33000
3

8
⚫If connecting leads and electric fence wires are installed near an over head
power line their height above the ground should not exceed 3m.
5
This height applies either side of the projection of the outermost
conductors of the power line on the ground surface, for a distance of:
• 2 m for power lines operating at a nominal voltage not exceeding 1000V;
• 15 m for power lines operating at a nominal voltage exceeding 1000V.
⚫Electric animal fences intended for deterring birds, household pet
containment need only be supplied from low output energizers to obtain
satisfactory and safe performance.
⚫Fence wiring should be installed well away from any telephone or
telegraph line or radio aerial.
⚫The size of the warning sign shall be at least 100mm x 200mm.
⚫The background colour of both sides of the warning sign shall be yellow.
The inscription on the sign shall be black and shall be either:
-the substance of “CAUTION: Electric Animal Fence” or,
-the symbol shown:
⚫The inscription shall be indelible, inscribed on both sides of the warning
sign and have a height of at least 25mm.
⚫Ensure that all mains operated ancillary equipment connected to the
electric animal fence circuit provides a degree of isolation between the
fence circuit and the supply mains equivalent to that provided by the
energizer.
⚫Protection from the weather shall be provided for the ancillary equipment
unless this equipment is certified by the manufacturer as being suitable for
use outdoors and is of a type with a minimum degree of protection IPX4.
This energizer complies with international safety regulations and is
manufactured to international standards. MGG reserves the right to make
changes without notice to any product specification to improve reliability,
function or design.

4. Installation guide
Positioning the energizer
Install the energizer:
Adjacent to the electric fence
Preferably in the middle of the electric fence and where it will receive the most daily sun
throughout the season
Where a good earth can be obtained
On firm ground away from flooding and out of reach of animals and children (inside a
protective fence, if required). The solar panel should face true north in the southern
hemisphere and true south in the northern hemisphere.
Mounting the energizer
The energizer can be mounted directly onto a 3cm x 2cm wooden batten using the
post-mounting slot at the rear. To mount onto a wooden post screw the batten to the post.
Also available from MGG are 3cm x 2cm plated steel stands.
Connecting to an electric fence
1 Push a 1m to 2m plated earth rod fully into firm ground. Must be plated as electricity will
not pass through rust.
2 Connect the black lead from the Fence earth terminal on the energizer to the earthing
system.
3 Connect the red lead from the Fence output terminal on the energizer to the fence.
Make sure there is a good contact.
Caution! Make sure the connecting leads drop downwards from the energizer to prevent
water from collecting at the terminals.
Operation
Switching on and off
1 When switched on the pulse indicator light flashes once for each output pulse.
2 When switched off the pulse indicator light stops
Battery protection
7
An intelligent battery management feature puts the energizer into Battery protection mode
when the battery charge falls below a ‘safe operating level’. When in Battery protection
mode the energizer is still on but it will not deliver a pulse to the electric fence.
The energizer will resume delivering pulses when the solar panel has charged the battery
so that it is above the ‘safe operating level’.
Alternatively, the battery can be recharged with a 12v battery charger connected to the
charge port on the rear of the energizer. The correct chargers are available from MGG
Products.
When fully charged, the battery should be able to power the energizer for up to two weeks
with no sunlight.
Replacing the battery
If a replacement battery isrequired, use a 7.4V, 10Ah, rechargeable lithium battery. Do not
use a non-rechargeable battery.
Do not dispose of the battery in a land-fill or in a fire.
Energizer maintenance
Clean the solar panel regularly with a soft cloth using glass cleaner or a mild solution of
detergent and water. This ensures the solar panel functions efficiently.
When transporting the energizer protect the solar panel to prevent the glass surface from
being damaged.
Energizer storage
If the energizer is stored for an extended period, the battery may self discharge and
become damaged.
The energizer should be stored inside with power off, better next to a window, where
sunlight can shine on the energizer each day.
If the energizer cannot be stored in a sunny position, it should be kept in a cool place. The
battery should be fully charged and powered off. The battery should be recharged
manually every three months using a suitable 12V battery charger.
Troubleshooting
Problem and action
1 The Pulse indicator light is flashing, but the electric shock delivered by the fence is
weak.
Check that the energizer is adequate for the length of the fence. If necessary, reduce the
length of the fence or reduce the number of fence wires. Alternatively, divide the fence-line
into smaller zones, with each zone powered by a separate energizer. NEVER EVER PUT
MORE THAN ONE ENERGISER ON THE SAME WIRE. THAT IS VERYDANGEROUS.
2 The Pulse indicator light is not flashing.
3 The battery needs frequent replacement.
Check that the solar panel is clean and is not damaged. Make sure the energizer is
positioned to receive maximum sunlight. If necessary, remove any objects or vegetation
8
that might be casting a shadow on the energizer.
5. Maintenance
Warning: Other than changing batteries, there are no user-servicable parts. If repair is
required please contact MGG.
Fault
Solution
The Pulse
indicator light is
flashing, but the
electric shock
delivered by the
fence is weak.
Check that all connections in the fence and earth system are firm
and secure. If necessary, clean away any corrosion.
Check that the earth rod is pushed firmly into firm ground and is
not rusty.
Check for faults in the fence-line caused by trees or vegetation. If
necessary remove obstructions and mend the fence.
Check that the energizer is adequate for the length of the fence. If
necessary reduce the length of the fence or reduce the number of
fence wires. Alternatively, divide the fence-line into smaller zones
with each zone powered by a separate energizer.
The Pulse
indicator light is
not flashing.
Check that the energizer is switched on.
If there has been insufficient sunlight to charge the battery the
energizer may be in Battery protection mode. Charge the battery
by placing the energizer in full sunlight with the solar panel facing
true north in the southern hemisphere and true south in the
northern hemisphere .
Try charging the battery manually using a suitable battery
charger. Replace the battery with a new battery. Before installing
a new battery charge it fully using a suitable battery charger or
leave in sun for 3 days with energizer turned off.
If the pulse indicator light is still not flashing, return the energizer
to the MGG for service
The battery needs
frequent
replacement.
Check that the solar panel is clean and is not damaged. Make
sure the energizer is positioned to receive maximum sunlight. If
necessary, remove any objects or vegetation that might be
casting a shadow on the energizer.
