Connecting the Sytronix system SvP 7030 electrically
XD04: External braking resistor
Function
Is used to connect the integrated or external braking resistor HLR. The braking
resistor is connected to the DC bus using an internal switch.
Installation instructions
Maximum allowed line length to external braking resistor: 5 m
Twist unshielded lines.
Overview
There are different types of connections:
● Screw connection at device (
● Screw connection at connector (
● Spring terminal at connector (

WARNING
50 V! Hot housing surfaces!
Risk of fatal electric shock! Risk of burning! Risk of fire!
The temperature of the housing surface of an external
HLR braking resistor can rise up to 150 °C. Run the
connection lines with a sufficient distance (> 200 mm)
to the housing of the HLR braking resistor to avoid dam-
aging the insulation of the connection lines. Outside of
the control cabinet, run the connection lines of an HLR
braking resistor in a metal pipe with a wall thickness of
at least 1 mm.
Do not touch any hot housing surfaces! Mount the HLR
braking resistor on a temperature-resistant mounting sur-
face. Provide a sufficient distance between the HLR
braking resistor and heat-sensitive materials. Make sure
the cooling air supply is unrestricted. Take care that the
environment can discharge the dissipation heat.
Danger by inadequate installation!
NOTICE
Protect the lines with the appropriate fusing elements in
the supply feeder.
For the connection lines at XD04, use at least the cross
section of the lines for mains connection at XD03. If this
is impossible, select the cross section of the connection
line at XD04 in accordance with the continuous power of
the braking resistor.
