Intended use / contra-indications

The Mach LED 8MC operating light is designed to illuminate an operating site in medical facilities (e.g. in a laboratory, in hospitals or doctor’s practice) with focused, low-glare, shadow-free light. It enables the user to perform a diagnosis or carry out medical interventions. The Mach LED 8MC light is an operating light that is not fail-safe when used as a single light. It is not intended for use in areas where explosions are likely although it is permissible to use it in the vicinity of HF surgical equipment.
Permanent illumination of the open human eye should be avoided when illuminating the face area.

Safety instructions

This symbol indicates possible sources of danger. Please also note the safety instructions and the hazard specification in the associated installation and operating instructions for the support arm system.
Pay attention to the instructions for use when handling the lamp.
Warning: to avoid the risk of an electric shock, this device must only be connected to a supply network that has a protective earthing conductor.
A primary-side ON/OFF switch to isolate the system from the supply network must be provided on site. The switch must meet the requirements of IEC 61058-1 for nominal voltage peaks of 4 kV.
This device is not designed for operation in environments enriched with oxygen.
The lamp may only be used for the intended purpose. Otherwise, the manufacturer will not be liable for personal injury or damage to property.
The lamp is equipped with a serializable handle at the factory and must only be used with this handle.
Changes to the light are prohibited and will invalidate the manufacturer’s certificate of conformity and all warranty claims.
Use only the mains units (or transformers) approved or supplied by the manufacturer. Non-observance will void the conformity of the product and release the manufacturer from any claims under warranty.
Installation, maintenance and repair work may only be carried out by the manufacturer or by specially trained staff.
Maintenance must be carried out on the light at least every two years
Additional equipment that is connected to medical electrical equipment, must conform to the relevant IEC- or ISO standards (e.g. IEC 60950 or IEC 62368 for data processing equipment). Moreover, all configurations must meet the requirements for medical electrical systems (see Section 16 of the latest version of IEC 60601-1). Anyone who connects additional equipment to medical electrical equipment, is configuring a medical system and is therefore responsible for ensuring that the system meets the requirements for medical electrical systems. In case of doubt, contact your local representative or our technical customer services.
The simultaneous use of several lights to illuminate a wound area may result in the maximum allowed energy input being exceeded (1,000 W/m2) and thus excessive heat development. It is the user’s responsibility to ensure that the maximum allowed limit is not exceeded.
The unprotected human eye can be damaged by direct light. Do not look directly into the light beam of the lamp. Do not point the light beam at the patient’s unprotected eye continuously.
Do not allow the laser beam to enter the eyes of the patient or user. The eyelid closing reflex of patients, in particular, may be impaired by this.
When positioning the light body, there is a risk of injury (e.g. crushing) and collisions with other objects (inventory) or walls.
Parts that fall off could injure the patient or lead to an infection of the wound area.
Do not remove the rating plate or the warning la-bels.
It is forbidden to carry out servicing or repair activities whilst the lamp is in use.
Lights with the camera preparation equipment may only be used with the camera or camera bay cover installed.
Simultaneous touching of parts on the luminaire and the patient is not permitted.

Cleaning and disinfecting

Cleaning and disinfecting work must only be done by trained staff. The respective requirements must be observed for all cleaning and disinfection work (details can be found in the manual).

Housing/protective screen

The housing and the protective screen of the lamp body can be cleaned and disinfected with many common/commercially available materials. Do not use cleaning agents or disinfectants containing active substances based on biguanides or phenols. Cameras must be removed and the camera bay cover put on prior to cleaning and disinfection.
Furthermore, only cleaning agents approved for polycarbonate (PC) may be used to clean the protective screen. To protect against mechanical damage, always use a damp cloth (never a dry one) to wipe the protective screen and after cleaning, wipe with an anti-static agent (lint-free cloth).

Serializable handle
The handle must be cleaned/disinfected before each use. It can be steam sterilized (max. 200 sterilization cycles for max. 5 minutes at a max. temperature of 134°C; details can be found in the manual).
Before installing the handle, check it for visible damage, fouling and the specified manufacturing date. Do not use damaged or dirty handles or handles that are more than two years old.

Faults

In the event of unusual operating conditions or a fault message dis-played on the display, the lamp must not be used, as safe operation cannot be guaranteed. For troubleshooting, disconnect the lamp from the mains for about 30 seconds. In the event of continuous faults, a suitably trained service technician must be contacted, stating the error code.

Information on electromagnetic compatibility

Medical electrical equipment is subject to special precautionary measures with regard to electromagnetic compatibility (EMC). They may only be installed and put into service in accordance with the EMC instructions in the accompanying documents. The Mach LED 8MC operating light has been tested for use in professional equipment of the health care system.

The lamp is suitable for use with an RF surgical device. There must be a distance of at least 50 cm between the surgical light, including the suspension system, and the RF electrode cables.
Portable and mobile RF communications equipment can affect medical electrical equipment and must not be used within 30 cm of the light, including the cable.
The use of this equipment immediately next to other equipment or with other equipment in stacked form should be avoided since this may result in faulty operation. Should use in the aforementioned manner nevertheless be necessary, this device and the other equipment should be kept under observation to ensure that they are working properly.
The use of different accessories, converters or cables to those that the manufacturer of this device has stipulated or made available may result in increased electromagnetic interference or reduced immunity to electromagnetic interference and to faulty operation.
Furthermore, the light must not be operated if the housing, cable or electromagnetic shielding is damaged.
Additional information on electromagnetic compatibility can be found in the manual.

Disposal

The light does not contain any harmful sub-stances. The components of the light should be disposed of appropriately at the end of the product’s life.
Take care that the material is carefully separated: The electrical circuit boards should be recycled appropriately. The housing of the light and the other components should be disposed of according to the materials they contain.
