4.1 Notes for installation
It is imperative you pay attention to the following warnings and safety instructions prior to
and during installation.
DANGER!
Risk of injury due to electrical power!
•
Carelessness will result in serious injuries or death.
Never wire or disconnect electrical connections while they are live! Before making any change
the device is to be disconnected from the mains. Even 10 min. (Size 1 to 4) / 30 min. (Size 5 to 7)
after mains off,
dangerously high voltages of ≥50 V may still be present (capacitor charge). So
check that electrical power is not present!
Work on the device must only be carried out after the DC link voltage has dropped below a
residual voltage of 50 V
(on Size 1 to 6A to be measured on the terminals X11/L+ and L-, on Size 7 on the terminals X11/
ZK- and X11/ZK+).
Dangerous voltage may be present at the device, even if the device is not emitting
any visual or audible signals/indications (e.g. with mains voltage applied to terminal X11 and
missing control 24 V DC on X9/X10 or X44)!
WARNING
!
Risk of injury due to hot surfaces on the device (heat sink)!
•
Carelessness may result in serious burns.
The device and especially the heat sink heat up significantly during operation and can reach
temperatures of up to +100 °C (+212 °F). Prior to starting work, make sure the device has
cooled down.
On touching there is a risk of burns to the skin. For this reason provide protection against
touching.
During mounting maintain an appropriate distance to neighbouring assemblies.
WARNING
!
Risk of injury due to hot coolant!
•
Carelessness may result in serious burns.
In operation the coolant reaches high temperatures. Prior to starting work, make sure the coolant
has cooled down.
NOTE:
Along with this operation manual, it is imperative the manuals for the Power
Supply Unit or the supplying AC-AC Servo Drive are read on installing the
complete MSD Multi-Axis System.
