P The drive and the chopper will withstand this continuous braking power. The braking is considered continuous if the
brcont
braking time exceeds 30 s.
Note: The braking energy transmitted to the specified resistor(s) in 400 seconds may not exceed E
R Resistance value for the listed resistor assembly. Note: This is also the minimum allowed resistance for the braking
resistor.
E Short energy pulse that the resistor assembly withstands every 400 seconds. This energy will heat the resistor
R
element from 40°C (104°F) to the maximum allowable temperature.
P Continuous power (heat) dissipation of the resistor when placed correctly. Energy E

All braking resistors must be installed outside the converter module. The SACE braking resistors are built in an IP21 metal
housing. The SAFUR braking resistors are built in an IP00 metal frame. Note: The SACE and SAFUR resistors are not UL
listed.

Resistor installation and wiring

All resistors must be installed outside the drive module in a place where they will
cool.
WARNING! The materials near the brake resistor must be non-flammable. The
surface temperature of the resistor is high. Air flowing from the resistor is of
hundreds of degrees Celsius. Protect the resistor against contact.
Use the cable type used for drive input cabling (see to chapter
ensure the input fuses will also protect the resistor cable. Alternatively, two-
conductor shielded cable with the same cross-sectional area can be used. The
maximum length of the resistor cable(s) is 10 m (33 ft). For the connections, see the
power connection diagram of the drive.
