Tightening torques for clamping
screws
Tightening the clamping screw with
the appropriate torque guarantees:
• secure and gas-tight connection
• No mechanical damage the
clamping parts
• A voltage drop well below the
permissible limit
The test torque IEC 60947-1 the
torque specified the manufacturer
is the lower value the permissible
torque range.
