Section 2: INSTALLATION AND INSTRUCTIONS FOR USAGE
The BR7000 is designed as panel mounting instrument in PFC-systems. This requires a
cut out of 138 x 138 mm according to DIN 43700 / IEC 61554. The controller has to be
inserted from the front and fixed with the clamps (included in delivery). The device may
only be installed by qualified personnel and may only be operated according the given
safety regulations. In addition the relevant legal and safety instructions have to be
obeyed.
The measuring input is designed for 1- and 3-phase grids with or without neutral
conductor. The maximum measuring voltage is 440V~ (L-N) / 760V ~ (L-L).
The supply voltage is 110...440 V +/-10%.
Wiring connections must be suitable for the particular voltages. Input leads have to be
protected by over-current-protection devices. The supply voltage must be protected by a
fuse; it must be possible to switch off the supply voltage by a separator.
The device must not be operated without protective earth contactor connected!
Before connecting the BR7000, it has to be checked that all connections are at zero
potential; current transformers have to be short circuited. Correct phasing of measuring
voltage and measuring current have to be checked. The measuring current circuits must
2
be wired with minimum 2.5 mm Cu.
Terminals may only be plugged when de-energized!
Attention!
During single-phase operation the coil voltage for the capacitor contactors must be drawn
from the same phase as the measuring voltage as only the measuring voltage is
monitored. (Protection against direct re-switching of contactors during a short-term
single-phase voltage drop.)
The controller may only be operated when installed. The complete programming of all
application-specific parameters is done according chapter programming. Then the device
is set to automatic operation by pushing the operation mode button. The controller is now
ready for operation.
Operating the controller without following to these operating instructions may be harmful
and dangerous!
