Resistor braking 165
P
brcont
The drive and the chopper will withstand this continuous braking power. The braking is
considered continuous if the braking time exceeds 30 s.
Note: Check that the braking energy transmitted to the specified resistor(s) in 400 seconds
does not exceed
E
R
.
R Resistance value for the listed resistor assembly. Note: This is also the minimum allowed
resistance for the brake resistor.
E
R
Short energy pulse that the resistor assembly withstands every 400 seconds. This energy will
heat the resistor element from 40 °C (104 °F) to the maximum allowable temperature.
P
Rcont
Continuous power (heat) dissipation of the resistor when placed correctly. Energy E
R
dissipates in 400 seconds.

22 kW with standard 22 ohm resistor and 33 kW with 32…37 ohm resistor
All brake resistors must be installed outside the drive. The SACE brake resistors are built in an
IP21 metal housing. The SAFUR brake 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 (refer to
Technical data on page 105)
to 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.
