5.3.3 Connection plan for mimimum wiring with internal brake resistor
Stop!
Always operate the ECS power supply modules with a brake resistor
(internal/external).
The ECS power supply modules in the standard built−in unit and push−through design
(ECSEE / ECSDE) are provided with a device−internal brake resistor.
In order to use the internal brake resistor (Rb), carry out the following wiring:
ƒ Bridge between the terminals X22/+UG and X22/BR0 (CR)
Current flow from +UG via the internal brake resistor (Rb) and the brake transistor to
−UG.
ƒ Bridge between the terminals X6/T1 and X6/T2 (CR)
Deactivate the temperature monitoring of the non−existing external brake resistor.
