2.7 Notes on decommissioning
Danger
HAZARD caused by high operating voltage and electric
shock!
Extremely hazardous voltages of up to 850 V may occur!
Please observe the following precautions in order to avoid muscle cramps, burns,
unconsciousness, respiratory standstill, etc., and death:
Have commissioning jobs carried out by qualified personnel only, see
chapter 1.1.3 "Qualified personnel", page 12.
Prior to commissioning, please do the following:
Reattach dismantled protective equipment and check it for proper
functioning.
By doing so, you will prevent accidents resulting from moving parts.
Secure the servo amplifier JetMove 204-480 against accidental contact
with conductive parts and components.
Only connect devices or electrical components to the signal lines of the
digital servo amplifier JetMove 204-480 (Enable, Limit+/-, REF, BRAKE 1
and BRAKE 2) that have been sufficiently isolated against the connected
electric circuits. These signal lines may only be connected with units that
have got the ground potential of the DC 24 V power supply.
The digital servo amplifier JetMove 204-480 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.
Each commissioning, even a short functional test, must always be carried
out with a PE (GND) bus correctly connected.
Before returning the device, remove the cable strap serving as strain relief
and motor cable shield.
