When press brake was shipped to the factory of buyers,the next thing is to install.we would like to say that nothing should be careless.it is more obvious to connect electricity.first of all,you need to confirm the machine is 50 Hz or 60 Hz,and this conform to your standard.then,you should begin to arrange lines.wrong connection would kill the operator or other people.so,we seriously ask the professional people to join in.we can not say too much in words.only take a note to you,all electrical must be connected with ground.all lines should be in the pipe in case the link is worn in future.
