Qualified Personnel; Due Diligence; Intended Use - Danfoss VLT ISD 410 Operating Instructions Manual

Safety Instructions
•
In addition to the L1, L2 and L3 supply voltage
inputs on the power supply module, the servo
system has other supply voltage inputs, including
external 24 V DC. Before commencing repair
work, check that all supply voltage inputs have
been switched off and that the necessary
3 3
discharge time for the intermediate circuit
capacitors has elapsed.
•
The supply of power to the servo system must be
switched off for repair work. Before disconnecting
or connecting the hybrid cable or disconnecting
cables from the connection box and/or the power
supply module, ensure that the mains supply is
disconnected and the necessary discharge time
has elapsed.
WARNING
HIGH VOLTAGE
The ISD 410 servomotors are electrically powered servo
drives with DC link circuits. The capacitors in the DC links
hold stored energy even after the supply voltage has been
switched off. The total capacitance of the DC link is higher
than that of an individual servomotor because the
servomotors in the system are configured as a group with
their DC links connected in parallel. For this reason, the
capacitor discharge times must always be observed
without fail.
CAUTION
Never connect or disconnect the hybrid cable to or from
the servomotor when voltage is present. Doing so will
damage the electronic circuitry. Observe the discharge
time for the DC link capacitors.

3.4 Qualified Personnel

Installation, commissioning and maintenance of the
ISD 410 servo system may only be carried out by qualified
personnel.
For the purposes of this document and the safety
instructions in this document, qualified staff are trained
staff who are authorised to fit, install, commission, earth
and label equipment, systems and circuits in accordance
with the standards for safety technology and who are
familiar with the safety concepts of automation
engineering.
Additionally, the personnel must be familiar with all the
instructions and safety measures described in these
operating instructions.
They must have suitable safety equipment and be trained
in first aid.
