Equipotential bonding between terminal box and machine housing 

The equipotential bonding between the PE terminals in the relevant terminal box enclosure 

and the motor housing is established via a fixing bolt on each terminal box housing. The 

contact point underneath the bolt head is bare metal and protected against corrosion.

Final steps 

1.

 

Before  closing  the  terminal  box,  please  check  that: 
– The cables are connected in accordance with the terminal diagram inside the terminal 

box cover 

– The inside of the terminal box is clean and free of any cable residue 
– The cable glands are firmly tightened, are suitable with respect to the degree of 

protection, type of cable routing, permissible cable diameter, etc., and have been 

mounted in full compliance with specifications and regulations 

– The connecting cables are arranged so that they do not come into contact with the 

machine, and the cable insulation cannot be damaged 

– The threads in the terminal plate are sealed using cable entries or sealing plugs that 

are suitable for the applicable degree of protection. 

– If necessary, any cable entries that are not in use are sealed and the plugs are tightly 

screwed in (i.e., so that they can only be removed using the suitable tools) 

– All of the seals/gaskets and sealing surfaces of the terminal box are in good condition 
– If bolt terminals are being used, all of the terminal bolts have been firmly tightened. 

This also applies to any unused terminals
