6.6. Maintenance of electrical system 

 

 

 

 

  Attention

 

Before  taking 

any 

action 

on 

electrical 

components disconnect  the machine from the 
mains. 

 
Always  carefully  check  the  isolating  covers,  the 
clamps  and  the  grip  of  the  sheaths;

 

seal  gaskets

 

cannot guarantee the IP level of protection declared 
by  the  manufacturer  if  they  are  not  correctly 
positioned or if they are damaged. 
Replace sheaths and cables if their isolating covers 
are ruined or damaged. 
Check  and  restore,  if  necessary,  the  identification 
labels  and  stickers  of  the  wires  and  of  the 
components keeping to the indications shown in the 
electrical diagrams. 
Make sure that the identification plate of the electric 
panel  and    the  adhesive  electric  hazard  plaque  are 
perfectly  legible  and  firmly  attached;  otherwise 
replace  them  by  requesting  new  ones  from  the 
manufacturer. 
The replacement of faulty control components must 
always  be  carried  out  according  to  the  norms  in 
force, 

using 

components 

with 

technical 

characteristics  complying  with  those  of  the 
components that need to be replaced. 
 
 

Use  exclusively  original  SELMI  spare 
parts 
The 

manufacturer 

will 

take 

no 

responsibility  for  accidents  or  damages 
in  the case o fuse  of  non-original spare 
parts. 
 

 

 

6.6.1 Disconnection and reconnection of the motor 

 
If  the  motor  needs  to  be  replaced  an  electrical 
technician will need to intervene. He will firstly have 
to disconnect the damaged motor and then connect 
the new motor. 
Follow these steps to disconnect the motor: 
 
1)  Remove  the  lateral  fixed  protective  panels 

following the instructions given in section 6.5.1 

2)  Remove  the  screws  of  the  connection  terminal 

protective box 

3)  Disconnect  the  wires  paying  attention  to  the 

terminal each wire is connected to. You will need 
to  remember  this  when  you  come  to  reconnect 
the wires 

4)  Free the cable from the cable holder that holds it 

to the motor and pull it out 

 

 

 

 

 

  Attention

 

Never  connect  the  power  supply  when  one  or 
more  of  the  electrical  components  of  the 
machine are disconnected and the conductors 
are not correctly isolated. 

 
To connect the new motor follow these steps: 
 
1)  Make  sure  that  the  electrical  characteristics  of 

the  new  motor  are  compatible  with  the  original 
one’s 

2)  Unscrew  the  protective  box  of  the  connection 

terminal 

3)  Reinstate  the  motor  power  cable  into  the 

appropriate cable holder 

4)  Tighten the cable holder until it has a good grip of 

the  cable,  paying  attention  not  to  use  too  much 
force,  as  there  is  danger  of  damaging  the  cable 
or the cable holder 

5)  Reconnect the wires into the connection terminal 
6)  Remount  the  protective  box  of  the  connection 

terminal and fix it in place with the screws.
