Electrical installation
Warning!
Damage to neighbouring assemblies and risk of injury due to hot surfaces
on the external braking resistor!
Carelessness may result in serious burns.
x Intensive thermal radiation is produced by the braking resistor (>300 °C).
x For this reason maintain sufficient clearance to neighbouring assemblies or install the braking
resistor outside the switch cabinet.
x If the braking resistor is mounted outside the switch cabinet, please provide adequate protection
against touching that reliably protects against hot surfaces.
For technical data on the design of the braking resistor, see “A.1.1 Technical data, brake
chopper” in the appendix.

DANGER! Risk of injury due to electrical power!
Carelessness will result in serious injuries or death.
x
Terminal BR is permanently connected to DC link potential (>300 V DC).
x Never make or disconnect electrical connections while they are electrically live! Always dis-
connect 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! Any existing additional DC link connections as well as the
connections for all components in the mains input area are to be checked in relation to each
other and in relation to earth to ensure they are not carrying any electrical power. If necessary,
all cable connections are to be discharged using suitable means.
Caution! Damage to the ext. braking resistor due to lack of temperature monitoring!
Carelessness can result in overheating of the ext. braking resistor.
x The external braking resistor must be monitored by the ServoOne CM-L charging module. The
temperature sensor (Klixon) in the braking resistor must have, as a minimum, basic isolation as
per EN 61800-5-1 in relation to the body of the resistor at mains potential.
x In the event of overtemperature, the supply unit is disconnected from the mains.
