Commissioning
2.7 2.7Notes on decommissioning
Before returning the JetMove, remove the strain relief/shielding bracket of the motor
cable.
WARNING
Hazard caused by high operating voltage!
Extremely hazardous voltages of up to DC 500 V may
occur!
Please, observe the following precautions in order to avoid injuries such as
muscle cramps, burns, unconsciousness, respiratory standstill or possibly death:
Have commissioning jobs carried out by qualified personnel only, see
chapter 1.1.3 "Qualification of Staff", page 12.
Before energizing the device make sure that the following
requirements are complied with:
Reattach dismantled protective equipment and check it for proper
functioning. This will protect the user from moving parts of the machine.
Secure the servo amplifier JetMove D203 against accidental contact with
conductive parts and components.
Only connect devices or electrical components to the signal lines of the
digital servo amplifier JetMove D203 (Enable1/2, Limit+/-, REF,
BRAKE+/-) that have been sufficiently isolated against the connected
electric circuit. These signal lines may only be connected with units that
have got the ground potential of the DC 24 V power supply.
Only connect position encoders to the servo amplifier if they are sufficiently
isolated from the connected mains and motor circuits.
The digital servo amplifier JetMove D203 has got a leakage current greater
than 3.5 mA. In order to avoid electric shocks, a second protective earth
conductor will be required.
For this, the measures listed in chapter 1.2.3 "Earthing Procedure", page
15, must be taken.
Every commissioning, even a short functional test, must always be carried
out with correctly connected PE bus.
