2. Key points in Disassembly
Points of attention in maintenance
(1) General attention
Be sure to pull off the power plug in disassembly or maintenance.
The wiring between the conductionwires mostly adopts AMP terminal. Keep the terminal in
good condition during dismantling or maintenance.
In inserting the conducting wires, be sure to plug the pins to the root and make it hard to be
pulled out.
If welding is needed,be careful not to touch the plastic or other insulation parts with the iron.
When connectingthe wires, be sure to keep the wire away from the mobile parts like the belt,
radiating pulley and jib etc., and the sharp protruding parts and the parts with high temperature
(motor). Connect and fix the wires as per their original mode.
If there's metal object at the wire fixing point, be sure to insulate with insulation materials.
Retain the dismantled screws for future usage in installation.
(2) Points of attention in usage of electric components
In case that the power is on, the earthing circuit of the computersequencer can have 220V
voltage to earth. T ake care not to get electric shock.
Store the computersequencer and driver under 4 -30 . Avoid direct sunlight.
In trouble-shooting, it may require hot-line work. Please be extremely careful to avoid electric
shock.
