GIRBAU PB32 Series Installation, Operation And Maintenance Instructions Manual page 11

14. BEFORE CARRYING OUT ANY inspection routine, adjustment, maintenance, repairs, cleaning or
any work on the machine, DISCONNECT IT FROM ALL THE ENERGY SOURCES.
- COMPLETELY disconnect the machine from the power supply and prevent the possibility of
accidental reconnection by mechanically locking the automatic external switch and/or the switch
breaker. Stopping the machine with the NORMAL STOP key or push-button is not enough.
- Disconnect the electrical connection of any circuit external to the machine; for example external
dosing equipment, external vending units, folders or ironer feeders. These circuits are independent
of the supply to the machine.
- Before beginning any procedure on machines equipped with an inverter or equipment with
capacitative loads, wait for at least five minutes (10 minutes on equipment with a power rating
greater than 25 kW) after the electrical disconnection, to eliminate risk of residual voltage.
- Close and mechanically lock the manual WATER, GAS, STEAM, THERMAL OIL, COMPRESSED
AIR, etc. supply valves.
- Check that the water bath has COMPLETELY drained, that no part of the machine is at an
excessively high temperature and that no parts are in movement through inertia.
15. DANGER! Some fault localisation procedures require checking at different points of the electric circuit
with the machine connected to the power supply and other supply sources. When carrying out these
procedures, respect the following instructions:
- The appropriate checks must be carried out by ONLY ONE PERSON.
- During these procedures, ONLY remove the protective covers from the electric circuit and/or the
inverter. Never remove the covers protecting the moving parts of the machine.
16. THE MANUFACTURER ACCEPTS NO RESPONSIBILITY IF THESE SAFETY INSTRUCTIONS
