Punching Holes In The Busbars - ALFRA 03200SET.NG Manual De Instrucciones

warning!
!
when bending busbars, there is the risk that small particles are ejected with high speed
from the machining area.
• wear your personal protective equipment for all work performed on the unit
(see section 2.4 "Personal protective equipment").
• Start the bending operation by pressing the foot-operated switch to the first pressure point
(foot pedal pressed approximately half the distance, corresponds to a force of approx. 20 kg).
The hydraulic pump is activated and feeds oil to the tool.
• Keep the foot-operated switch pressed until the electronic angle shutdown switch ends the
bending operation. The pump is deactivated and the tool travels back to its initial position.
• To interrupt the bending operation: hold the Pause push-button down.
The bending operation is resumed when the Pause push-button is released.
• To cancel the bending operation: press the Stop push-button. The machine returns to the initial position
and the bending operation may need to be restarted with the foot-operated switch.
note:
Depending on the material thickness and properties, the angle setting on the unit may need
to be adjusted slightly to achieve the desired bending angle of the busbar. once the angle has
been set correctly, it does not need to be readjusted provided the same material is machined.
• To switch off the pump, turn the mains switch to the "0" position.

10. PunchIng holes In the BusBars

Holes are punched in the copper or aluminium busbars with a male die (31) and the appropriate
female die (33). Slot male and female dies have additional pins (37) or grooves (39) to simplify an
exact angular positioning.
note:
observe the details for the minimum and maximum size of the holes to be punched in the
technical specifications (see section 5 "technical specifications").

note:
use only sharp male and female dies. oil the male die regularly to extend the service life
of the tools and to simplify return travel to the initial position.
