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 significantly 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 find the exact specifications 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.
