PROTECTION SYSTEMS
• Short Circuit Protection – The RITE-POWER Generator will shut down until the fault is
removed. It will signal this by flashing the red LED continuously and a beeper will be heard.
• Overload Protection – The RITE-POWER Generator will shut down until the load is reduced.
It will however allow small overloads up to 120% for short periods of time up to a minute. It
will signal this by flashing the red LED continuously 5 times which will then be repeated and a
beeper will be heard until the fault condition is removed.
• Over Temperature Protection – The RITE-POWER Generator will shut down until it has cooled
sufficiently to allow it to function again It will signal this by flashing the red LED continuously 4
times which will then be repeated and a beeper will be heard until the fault condition
is removed.
• Low Battery Voltage – The RITE-POWER Generator will shut down until the battery has been
recharged sufficiently It will signal this by flashing the red LED continuously and a beeper will
be heard until the unit is switched off or recharged.
• Low Battery Capacity Shut Off – The RITE-POWER generator has shut down due to insufficient
battery capacity. It will signal this by flashing the red LED continuously twice which will then
be repeated and a beeper will be heard until the unit is switched off or recharged.
• Automatic shut down - The RITE-POWER Generator will automatically switch the inverter
output off if no load or a small load is detected aer 12 hours. Switch power button off then
on to reset unit to resume normal function.
• Over Voltage Protection – The RITE-POWER Generator will shut down if the voltage from
the battery/charger rises above a particular threshold, if this happens this would suggest a
permanent fault in the charging system or an incompatible charger has been connected, the
issue should be investigated by a competent person – please contact Ritelite (Systems) Ltd or
its authorised distributor. It will signal this by flashing the red LED continuously 3 times which
will then be repeated and a beeper will be heard until the fault condition is removed.
Note in most cases the inverter will automatically reset itself aer a fault condition has been
removed, in some cases it may be necessary to switch off then back on the power switch to
reset the unit.

11
The RITE-POWER Generator is fitted with an appropriate 110V or 230V 30mA RCBO to add an
additional layer of protection over that mentioned above. However, all these protection systems
can’t mitigate against all dangers and situations. Please see the HSE document 482/2 https://
www.hse.gov.uk/foi/internalops/ocs/400-499/oc482_2.htm which should be strongly
considered and the appropriate risk assessments made to protect all users and those likely to
come in to contact with the mains power generated by the RITE-POWER Generator. There is
particular onus on regular inspection of cables, plugs, sockets and equipment connected by a
competent person to make sure any likely hazards are significantly reduced. Appropriate cables,
plugs, sockets and equipment must be used for the environment in which the RITE-POWER
Generator is to be used.
GUIDANCE ON EARTHING AND PROTECTING USERS
The RITE-POWER battery generator references the neutral to the earth system. This allows the
RCBO fitted help protect users as much as reasonably possible in the event of a fault occurring
with cables and/or equipment connected to the output.
In addition, there is an external earth point (Next to the outlet socket) on the product that can
be connected to true earth using a suitable recognised earth cable, please seek the advice of a
qualified electrician if this is to be done. Feasible methods for true earth connections are:
1) An earth rod driven to a depth of not less than 1 metre.
2) The earth terminal of an adjacent fixed installation.
3) Permanent Structural steelwork.
4) Exposed reinforcement bars in concrete foundations or structures.
5) A suitable metal structure known to be earthed.
It should be stressed that it is paramount to use equipment and cables suitable for the
environment they are to be used in to make sure a user can be afforded the maximum protection
against the likelihood of electrical shocks especially in harsh environments where cables and
equipment are subjected to far more physical damage.
Consideration should be given for environments where water is present or could be present
from rain or other liquids from elsewhere. Equipment and cables, plugs and sockets should be
examined regularly for signs of damage, both physically or through water ingress. Regular PAT
(Portable Appliance Testing) should be done according to the associated risks in the environment
the equipment is to be used.
The RITE-POWER Generator and equipment powered from it should be inspected before and
aer use and those inspections documented. If any damage or concerns are highlighted, then
the RITE-POWER Generator and/or equipment must be taken out of service and marked up
accordingly so it can’t be used until repair/inspected by a suitable qualified person.

12
Section 4: SETTING UP THE RITE-POWER GENERATOR
Inspect the proposed area for use.
An inspection of the proposed area in which to set up the RITE-POWER generator is necessary to
ensure it is suitable for safe operation. This inspection should be performed by the operator prior
to using the RITE-POWER generator.
The area should be free from moving vehicles, machinery, pedestrians or other factors which may
mean the RITE-POWER generator could form a hazard.
Set the RITE-POWER generator up in such a way that it cannot obstruct walkways or areas that
form emergency exit routes.
Do not leave unattended if there is potential for minors or non-competent persons to tamper with
the RITE-POWER generator whilst in use.
Operators should be aware of the following possible hazardous situations. The operator
should also remember these hazards, watch and avoid them while moving, setting up and
operating the RITE-POWER generator.
• Forming a trip hazard
• Mains electricity at 110V AC or 230V AC (depending on model) is produced by
this product.
• Minors or non-competent persons
• Debris either on proposed site or on route to site
• Inadequate surface support to withstand the RITE-POWER generator weight
• Water which could allow the RITE-POWER generator to be submersed
• All other possible unsafe conditions

13
Section 5: OPERATING INSTRUCTIONS
Do not use the RITE-POWER generator for any purpose other than that for which it is designed – as
a portable mains electricity generator.
If more than one operator is expected to set up or use a RITE-POWER generator at different times,
each operator is required to follow all safety rules and instructions in the operator’s manual. That
means every new operator should perform a pre-operation inspection and function tests before
using the unit.
5a) PRE-OPERATION INSPECTION
Always perform a pre-operation inspection.
The Pre-operation inspection is a visual inspection performed by the operator prior to each use of
the RITE-POWER generator. This inspection is designed to discover if anything is obviously wrong
with a unit prior to use.
A damaged or modified RITE-POWER generator must never be used. If any damage is discovered
the RITE-POWER generator must be removed from service until it has been repaired and
appropriate clear labelling added to warn and prevent its use.
Maintenance and repairs can be executed only by authorised personnel. If any person maintaining
or repairing the device is in any doubt, they should contact their supplying dealer or Ritelite
(Systems) Ltd.
Check the following parts or areas for any signs of damage or missing parts.
• Cables (for kinks, frays, abrasions, bare conductors showing)
• Plugs and Sockets for physical damage
• Catches and locking mechanisms.
• Make sure the case is free from cracks or areas of damage where water could enter
• Make sure all labels and warnings are present and readable on the product as detailed on the
following pages.

RITE-POWER 3850
RITE-POWER 7700
Note All labels shown above show one voltage only. Labels will differ between 110V and 240V
units. Units with built in chargers will have slightly different labels to include extra weight and
different basic instructions for use.

15
5b) USING THE RITE-POWER GENERATOR
1. Check there is sufficient battery capacity for the
task in hand, this is indicated by the display on the
front of the unit showing the battery capacity in a
percentage, where 100% is full capacity.
3. Make sure the RITE-POWER generator is
switched off via the button next to the display. The
display will automatically light up when the unit is
switched on and go dark when the unit is switched
off to conserve power when not in use.
4. Make connections to the mains output socket at
the rear of the RITE-POWER generator. Making sure
the output voltage of the RITE-POWER generator
is within the constraints of the equipment to be
powered from it.
2. If necessary, recharge the RITE-POWER
generator. As a point of note it is good practice to
always recharge the unit to full aer every use.
Chose a suitable location, heeding the warnings in sections 4 & 5 of this manual.

16
5. Check the device to be powered is within the maximum constraints of the RITE-POWER generator, see
technical specifications contained within this manual and on the RITE-POWER generator. Heed the notes in
the section Applications and Restrictions of use with regard to Inductive, Resistive and capacitive loads and
their limitations.
6. Once everything is connected press the power on
button. The display will light up and a red LED should
light in the middle of the switch to indicate that mains
power is on and everything is ok.
7. Note the estimated run time on the display, this will
vary according to the load driven by the RITE-POWER
generator. In the example here the display indicates 3
hours, 54 minutes remaining at the current
power drawn.

The display also shows various other parameters such as wattage, this can be a useful gauge to understand
what different powers are consumed by different equipment and the runtime that might be expected.

17
8. Certain equipment such as some lighting can be
dimmed, this can be useful to extend the runtime
required while still potentially providing enough
light for the task in hand.
9. In use note the fall of the battery capacity so
power isn’t suddenly lost unexpectedly. Once the
RITE-POWER generator gets towards the end of the
available capacity a beeping will be heard from the
unit and the red LED in the middle of the switch will
flash to denote the low power level, depending on
the size of the load being drawn will dictate how
soon until the load is then switched off.
10. Once the load has been switched off from the
depleted power pack the switch should be pressed
to switch the system off and the pack placed on
charge as soon as possible.
Note – If the battery is le to run completely
empty aer the low battery warning has
been indicating so for a while, the battery will
completely shut down and the display turn
completely off to preserve it’s lifetime. Please
ensure it is then recharged within 12 hours.
See note under charging.

18
5c) RECHARGING THE RITE-POWER GENERATOR
1. The RITE-POWER generator should be placed on charge to return it to full capacity once used. Choose
a suitable location to recharge the unit away from any aforementioned hazards. Ideally the RITE-POWER
generator should be charged in a cool ventilated environment.
Note – It is good practice to always keep the RITE-POWER generator fully charged up so it is always ready
for use.
3. Plug the charger into a suitable mains supply and
switch the power on.
Note – charger connections to the RITE-POWER
generator should always be done with the mains
power off to the charger, once connected the mains
supply to the charger can then be switched on.
2. Plug in either the SLK350CH, SLK750CH
or SLK1000CH charger into the RITE-POWER
Generator via the white 32A industrial connector,
turn the plug locking ring to secure the plug to the
socket and aid a secure connection.

19
5. Check the display on the RITE-POWER generator, once the charger is connected and everything is ok
the display will blink slowly as energy flows into the battery to recharge it. You can monitor progress on the
display, the capacity percentage will gradually rise as will the capacity in AH and the voltage. The run time
display will now show an estimated time to complete the charge process. You may notice the energy go in
slowly to start with, this depends on the state of discharge of the battery.
4. The charger will display via its LED indication once powered up, see the instruction manual for the charger
for a full guide to it’s operation.
ESTIMATED RECHARGE TIME TO
FULL 100%
Note – If the display is blank or no energy appears to be flowing into the battery on the display, switch
the power button on, this should wake up the battery to start charging - this only happens if the battery
has been le in an over discharged stage. Once energy is seen to be flowing in the power button can be
switched off - make sure any mains plugs are disconnected from the output.

20
6. Once the display shows 100% the power pack is fully recharged, the charger can be switched off and
disconnected from the power pack. Make sure the power pack is always switched off via the button next to
the display when not in use to prevent any unnecessary discharge.
5d) OPTIONAL ‘PASS THROUGH’ POWER TRANSFER SYSTEM
If this option is fitted this allows a 3850 or 7700 battery generator to receive mains power in from either a 110V
or a 240V AC source (the source must be the same voltage rating as the battery generator) and pass it through
to the output socket of the battery generator to drive a load. The load must be not greater than the max output
of the battery generator as per its specifications and limitations as detailed in ‘Applications For Use’ on page 4
of this manual.
This option is useful if a simple mains failure back up is needed to provide power in the event of a grid failure or
power failure from a traditional petrol or diesel generator.
In addition, you can link multiple battery generators together which have this same functionality, effectively
this will give a longer duration to run the load and as the first supplying battery generator runs out of charge
this will automatically cause the next in line to take over and so on. All that’s required is a 3 core mains cable
with a male plug to female coupler in the appropriate voltage type linking the packs. Switch over time is
typically less than 20 milliseconds.
Setting up a system
To set up a system connect a suitable power cable from the mains outlet of a fixed installation or generator to
the battery generator input socket. Use appropriate connectors with the same IP67 locking system to provide
a secure and watertight connection. Use an appropriate outdoor cable with the connectors such as a rubber
HO7RN-F with a 2.5mm cross section cable, an earth conductor MUST be used to afford the safest setup
and allow any RCBO’s to work effectively. Note – Ritelite (Systems) Ltd can supply suitable cables as required,
please contact the sales office for information.
Before connecting any output loads to the battery generator turn the red battery isolator switch to ‘On’, then
switch on the battery generator by depressing the green button, the LED on the green button should now
show a constant red (if it flashes this indicates a fault condition, please see ‘Protection Systems’ page 10 and
‘Troubleshooting’ page 23 in this manual if this occurs).
