14 Electrical Installation
Pinout for the connector can be found in chapter "Connector Pinout" from p.131. Pinout
of the servo amplifier's end can be found in the instructions manual of the servo amplifier.
14.1 Important notes
Only staff qualified and trained in electrical engineering are allowed to wire up the motor.
Always make sure that the motors are de-energized during assembly and
wiring, i.e. no voltage may be switched on for any piece of equipment
which is to be connected.
There is a risk of death or severe injury from touching exposed contacts.
Ensure that the switch cabinet remains turned off (barrier, warning signs
etc.). The individual voltages will only be turned on again during setup.
Never undo the electrical connections to the motor while it is energised.
Risk of electric shock ! In unfavorable circumstances, electric arcs can
arise causing harm to people and damaging contacts.
A dangerous voltage, resulting from residual charge, can be still present
on the capacitors up to 10 minutes after switch-off of the mains supply.
Even when the motor is not rotating, control and power leads may be live.
Measure the DC-link voltage and wait until it has fallen below 40V.
The ground symbol X, which you will find in the wiring diagrams, indicates that you
must provide an electrical connection, with as large a surface area as possible, between
the unit indicated and the mounting plate in the switch cabinet. This connection is to sup-
press HF interference and must not be confused with the PE (protective earth) symbol
(protective measure to EN 60204).
To wire up the motor, use the wiring diagrams in the Installation and Setup Instructions of
the servo amplifier which is used.
