DANGER! Risk of injury due to electrical power!
• Carelessness will result in serious injuries or death.
Never make or disconnect electrical connections while they are electrically live! Always disconnect
the power before working on the device. Even 10min. after switching off the mains supply,
dangerously high voltages of ≥50V may still be present (capacitor charge). So check that
electrical power is not present!
Terminal L+ (Size 1 to Size 4) or BR+ (Size 5 to Size 7) is permanently connected to DC link
potential (>300VDC). The connection is not protected internally in the device.
WARNING!
Risk of injury due to hot surfaces on the ext. braking resistor!
• Carelessness may result in serious burns.
The braking resistor heats up very signicantly during operation and can reach temperatures of
up to +250 °C (+482 °F). On touching there is a risk of serious burns to the skin.
CAUTION!
Damage to the external braking resistor due to lack of tempera-
ture monitoring!
• Carelessness can result in overheating of the ext. braking resistor!
The external braking resistor must be monitored by the controller. The temperature of the
braking resistor is monitored by a temperature sensor (Klixon). In the event of overheating the
servo drive must be disconnected from the mains supply.

NOTE:
You will nd the exact specications of the braking resistors, in particular the
surface temperature, the maximum supply voltage and the dielectric strength
at high voltages in the MSDServoDrive Ordering Catalog.
Please consult your project engineer for more detailed information on the design of
braking resistors.
