SAFETY STANDARDS TO COMPLY WITH WHEN THE EQUIPMENT IS TURNED OFF
Before servicing the equipment, disconnect all circuits.
Make sure that no voltage whatsoever is present in the circuit.
Clean and dry the whole area.
Remove pins, rings, brackets or any accessories which may hinder operations or turn into a potential
electrical conductor.
Ground discharge to earth or short circuit the capacitor terminals connected with the deactivated circuit.
Remove the fuses only after the circuit has been deactivated.
SAFETY STANDARDS TO COMPLY WITH WHEN SERVICING LIVE EQUIPMENT
Add the following provisions to those under items 2, 3 and 4 above:
• Personnel must never operate alone
• If possible, use only one hand to perform work required
• Check wires and instruments regularly
• Use only approved procedures to bypass the interlocks
• Ensure that operators are familiar with equipment parts and maintenance procedures, before servicing the unit
• Use a pair of safety gloves
• Open all contacts which feed power to the equipment before measuring resistance levels; verify there is no high
voltage in the low voltage circuits
• Do not use magnetic tools RDXC in the proximity of strong magnetic fields
SAFETY STANDARDS TO COMPLY WITH WHEN SERVICING THE UNIT
If continuous duty is not required, the system must be turned off. Before commencing work, the following
is required:
• Check that the maintenance technician is not carrying any objects which may act as conductors
• Inspect the work area to make sure the floor is clean and dry
• Check work tools. They must be suitable for their designated task and in good working order to ensure safe
maintenance operations
• Check that all gauges are regularly calibrated
• Check servicing procedures before commencing work by inspecting the wiring diagram and visualizing the system
structure
When carrying out electrical maintenance operations, the following is required:
• The maintenance technician must be familiar with high voltage circuits
• No resistance measurements are to be carried out on live circuits
• Use only one hand to take measurements on live circuits
• Earth all instrument terminals before taking measurements on live circuits
• The above recommendations must be strictly adhered to
Maintenance operations shall be deemed to have been completed only when all parts have been re-
installed and the product has regained its original appearance
FIRE HAZARDS
No direct danger
TOXIC SUBSTANCES
None
DANGERS ARISING FROM FLUIDS
Danger only arises if the fluid is dispersed in the installation site. This creates danger for passage by
persons.
The same danger exists if condensate, generated by the unit, is not collected and discharged to a suitable
drain.
