HANDLING
OR
ROTATING
MACHINERY
•
Never service rotating machinery, bands or chains when rotational movements are activated.
•
Make sure that the rotational movements are switched off.
•
Make sure that nobody can switch on the movements accidentally.
•
Block the movement, if necessary.
Safe handling of tilting machinery
•
Never service tilting machinery when tilting movements are activated or brakes are released.
•
Make sure that the tilting movements are switched off.
•
Make sure that nobody can switch on the movements accidentally.
•
Block the movements, if necessary.
If you tilt the machinery during installation or during other service activities:
•
Comply with the specific service instructions.
•
Ask a second person to release the brake and to keep the tilting movement under control.
•
Avoid uncontrolled tilting movement.
•
Never release the brake longer than necessary.
Hazard of physical injury caused by heavy loads
•
Wear appropriate protective clothing, such as safety boots an gloves.
•
Take care that heavy loads are correctly lifted or carried to avoid any physical injury.
•
Ask other persons for help to handle very heavy or awkwardly shaped loads.
•
Use mechanical devices whenever it is possible.
•
Stick to the installation instructions regarding:
•
suitable tools
•
lifting devices
•
lifting/support points
•
particular safety measures
If you do not obey these instructions, there is a risk of property damage.
Safe handling of light source
Light source and adjacent parts can be very hot. They can cause severe burns.
•
Never touch the light source, light source socket, or light source bracket with your fingers immediately after use.
•
Leave the light source and adjacent parts to cool down before handling them.
Precautions Against Electrical Hazards
Hazard of electrical shock during service tasks
During installation , maintenance, and other service tasks there is a risk of electrical hazards.
•
Follow the general instructions provided in this chapter.
If you do not obey these instructions, there is a risk of property damage.
General precautions against electrical hazards
•
Switch off the mains supply.
•
Make sure that nobody can switch on the system accidentally before you start.
•
Make sure that all UPS-powered components are powerless.
•
Use a voltmeter to verify that all line disconnects are opened.
•
Remove all jewellery, such as bracelets, or rings to prevent short circuits.
Precautions concerning installation and service
Electrical installations of medically used rooms must comply with the requirements of each country.
Follow the instructions provided on the installations sheets for the specific project.
•
Always use a separate conductor for ground connection. The neutral conductor is not considered as ground
connection.
•
Do not use a three-to-two pins adapter to connect equipment provided with a power cord. Always connect the
equipment to properly grounded, three-pin power outlets.
•
Connect the system to the mains as late as possible during installation.
•
Make sure that all protective earth conductors are installed and connected before first switching on the system.
•
Always be sure that the power is switched off when installing any parts to the equipment.
•
Make sure that the large internal capacitors are completely discharged. Discharging can take several minutes.
•
Keep away water or other liquids from the inside or the equipment to avoid short-circuits or corrosion.
•
After installation or service work on electrical components the following test have to be performed to ensure the
compliance with IEC 62353:
•
Touch voltage
•
Protective earth conductor resistance
•
Earth leakage measuring
