Safety information
Warning
Indicates a hazardous situation which, if not avoided, could result in death or serious injury.
To avoid risk of electric shock:
•Features in adjacent components may pose a risk to insulation and lead to electric
shock. Before repair work commences, assess the surrounding area for potential
hazards posed by adjacent components and plan the task to avoid those hazards.
This might include sharp edges, traps, fiddly or hard to reach areas. Temporarily
remove and replace adjacent components that could prevent safe access to the
working area or could be over stressed or damaged during the repair.
•If not fitted correctly, connectors can separate and lead to electric shock. Ensure all
connectors are fully pushed home and secure.
•Lose wires and cables can lead to excesses stress on insulation and lead to electric
shock. Ensure wires and cables are properly secured using the fixing locations
provided.
•Wires or cables getting trapped between parts during reassembly can lead to
compromise of insulation and lead to electric shock. This can occur between bosses
or enclosure parts. Check that no wires or cables are trapped when parts are
reassembled.

•Using incompatible parts can affect integrity and safety and might lead to electric
shock. Where a Mk3 parts is specified, replace with a Mk3 part. Same for Mk2.
•Using parts of inappropriate design or quality can lead to electric shock. Only use
genuine RootWave spares that have been supplied by RootWave.
•Accidental damage to insulation during repair caused by tools such as cutters used
for removing zip ties can lead to electric shock. Ensure care is taken when using sharp
or abrasive tools not to damage insulation. If in any doubt about whether a part has
been damaged replace the part with a new one.
•Accidentally leaving parts, debris, waste or tools inside repaired equipment can lead
to damage to insulation or compromise creepage and clearance distances and lead
to electric shock. Thoroughly check for foreign bodies before closing enclosers.
•Fluid spills into the equipment can lead to electric shock. Keep drinks, food and any
other liquids away from equipment during repairs.
•Damaged enclosures can lead to electric shock. Check integrity of enclosures and if
necessary replace with new parts.
•You should not fault find with the Power Module lid removed and the system
powered on and HV activated.
•Wear dielectric insulating boots.
•Ensure that screw fixings are tightened to a suitable torque. This is particularly
important for those making electrical connections, for example, the HV connection in
the Treatment Return.
•Repairs being completed by technicians without adequate technical training and
expertise may lead to errors that result in electric shock. If you are carrying out
repair tasks ensure you meet the required criteria to qualify as a Technician for these
activities.
•Carrying out repairs at an inadequate workstation can lead to errors and electric
shock. Repairs to be carried out in suitable workstation environment –see below.
•Once repair is complete use a electrical insulation tester to check for any indication
of breakdown –see below for further instructions.
•During repairs do a visual inspection of the internals look for any signs of arcing
including carbon deposits or heat damaged or melted components, cracks, any signs
of damage, loose connections. Always change parts that show any of the above signs.
•If in any doubt please contact RootWave support.

Final Checks
Once any repairs are complete
1. Electrical continuity test
Complete an electrical continuity test. This is detailed in SG2.
2. High voltage electrical insulation breakdown test
An insulation breakdown test must be carried out following either:
•Repairs to high voltage components
•Repairs carried out to areas adjacent to high voltage components that could cause
unintended compromise to high voltage components.
This checks the state of electrical insulation and the presence of any shorts which if
undetected could be hazardous or lethal to operators.
For details of how to safely perform insulation breakdown testing see RootWave document
PRO_Work_Intruction_09.
Insulation breakdown tests can also be used to support annual service checks and fault
diagnosis.
3. Functional check
Complete a functional check to ensure the system functions correctly after any repair work.
Follow the Pro Functional Check Protocol U-FCP-PRO-001-3, which is available for download
from rootwave.com/pro.
4. Labels
Once the system has been qualified, a tamper evident label can be applied to the enclosure.
You should also attach a service by and date sticker.

Technician qualification
The technician should be qualified to the following levels:
•Qualified as a minimum to NVQ level 3, or an equivalent European standard, in an
electrical subject, or demonstrably equivalent skills and experience. The qualification
must demonstrate that they can apply technical knowledge and skills to a range of
activities - including some that are complex and non-routine - and can act
responsibly, with autonomy and may be able to supervise others.
•Familiar with the use of standard workshop tools such as side cutters, knives, torx
and screw drivers, riveting tools, spanners, drills, torque drivers, crimping tools,
multimeters and electrical insulation testers.
•Competent in workshop and electrical Health and Safety, including high voltage
Alternating Current (AC) systems, able to carry out a risk assessment and define and
follow safe working practices and maintain a tidy and organised environment.
•Follow instructions without taking shortcuts, will abide by warnings and cautions, will
ask for help or clarification if they are unsure or if something is unclear.
•Complete all work to a high standard and inspect at key steps.
•Competent to sign off systems for release to users following repair, upgrade and

•A generator and a long power cable are available - a long power cable allows the
generator to be placed at a sufficient distance from the Power Module so that the
safety contact relays or any unwanted noise from the machine can be heard.
•The equipment under test is easily accessible.
•Fire suppression equipment is easily accessible and in good condition.
•A first aid kit is available and in good condition.
•If loan working is required then this has been risk assessed and a suitable protocol is
in place.
The workstation can be at a temporary outdoor location if all the above requirements are
met.
Key features
Earthing and safety
•The Power Module enclosure is earthed to the supply and through the Safety Earth
•The Secondary side of the transformer is earth referenced.
•The input side of the transformer is tied between Live and Neutral.
•Each connector link used to couple the Treatment Return and Safety Earth are
directly tied to Power Module enclosure.
•A single channel Industrial safety relay is used to interrupt the 24V coil drive signal to
each of the three intermediary drive relays. The outputs of each intermediary drive
relay loop through the mechanically linked normally closed contacts of the other two
safety contactors to prevent multiple tapings on the primary side of the transformer
being driven simultaneously. So, if High is being actively driven, the drives to the
Medium and Low contactors are disabled.
•Each safety contactor is a three-pole variant and the transformer drive signal loops
back through three times, so if any one of the three phase contacts fails closed two
others remain to prevent injury. The auxiliary contacts of each contactor only close if
all the three internal phase contacts open at de-energisation. Therefore, the system
is fault tolerant to two phases of any single contactor failing closed.
•The industrial safety relay and its emergency stop are independent of all other
control systems.
•No energy storage mechanisms are utilised in the high-power pathway.
•A Lance loopback is included to ensure the main Power Module to Treatment Lance
cable is connected before the safety relay will turn on.
Deployment and access control
•Without Treatment Return and Safety Earth foot compression the system will remain
open.
•If the safety relay is activated it is not possible to reset the system until, the E-Stop
fault is cleared, and the foot compression is confirmed.
