2 Safety information for service technicians
Safety information for service technicians
2.
BOWA-electronic places great emphasis on safety when working with electrosurgical units. This section contains information on:
Safety instructions
Warnings
The safety instructions in the User Manual contain information relevant to correct handling of the electrosurgical unit.
2.1.
Safety information
Electrosurgical equipment is subject to rigorous inspections by specially trained personnel. Only experienced and trained personnel may work with the electrosurgical unit. BOWA assumes that the electrosurgical unit will be maintained by qualified or authorised personnel. Service technicians must be trained and familiar with the basic principles, rules of maintenance and risks posed by the electrosurgical unit in order to ensure that patients, personnel and equipment are never put in danger.
2.2.
Warnings and safety instructions
2.2.1.
General instructions
20
Only use the electrosurgical unit until the self-test has been performed correctly (see User Manual). Position the electrosurgical unit safely; do not place it on top of electrical equipment.
Do not place any objects (e.g. tools) on the electrosurgical unit.
Avoid harmful interference effects by placing the electrosurgical unit as far away as possible from other electrical equipment.
Take suitable safety precautions before working on the electrosurgical unit, use isolating transformers, insulated tools and materials.
Connect the accessories only to the sockets specified.
Set the activation signal volume so it is loud enough to be heard.

900-400_SM_V2.1.0_11747-S0-20160601-EN
2 Safety information for service technicians
2.2.2.
Special instructions
If necessary, the electrosurgical unit can be connected to the potential equalisation system by means of an earthing cable.
Replace sub-assemblies only with sub-assemblies of the same type and quality.
Use antistatic containers to transport components that could be damaged by static electricity.
2.2.3.
Working with the unit switched on DANGER Since the unit's components are not insulated against contact with foreign objects, there is high risk of electric shock with potentially fatal consequences!
Work must only be carried out by qualified or authorised personnel.
Connect the electrosurgical unit directly to an earthed socket.
Do not use mains extension cables, adapters or multi-way sockets.
Use a 1000 VA isolating transformer if you are working on the unit when it is open. Ensure that the electrosurgical unit and all of its accessory parts are operated in dry conditions. Do not touch any unprotected cables or PCBs.
Do not use any earthing straps when working on a live electrosurgical unit.
Overheated or unsuitable components and inflammable materials pose the risk of fire or explosion.
Ensure that the electrosurgical unit has sufficient cooling.
Do not use any inflammable materials, such as anaesthetics, gases or fluids, around the electrosurgical unit.
If accessories are overheated, remove them from the electrosurgical unit and keep them away from the unit and personnel.

2 Safety information for service technicians
2.2.4.
Working with the unit switched off
The components are not insulated against contact with foreign objects. There is a risk of electric shock from electrically charged components even after the unit is switched off.
Switch off the electrosurgical unit and pull out the plug at least 5 minutes before commencing any service work.
Check for zero voltage by measuring the DC voltage between measuring points JP8 and JP3 on the power board (see Figure 2-1)
JP8
JP3
Figure 2-1: Zero voltage measuring points
CAUTION Risk of injury due to electric shock!
Voltages up to 380 V DC may be present.
Set a suitable voltage range on the measuring device.
Use an electrostatic discharge wrist strap and ESD mats, in order to prevent damage to the electronic components.
The electrosurgical unit can be damaged by incorrect use of tools and associated materials.
Do not clean the electrosurgical unit with cleaning agents which could cause damage or scratching.
Follow the cleaning instructions in the User Manual. When carrying out maintenance work, also observe the warnings and safety instructions in the User Manual.
