Pin Conguration
The DC Terminal block is designed to allow a DC cable to be attached leading to the front or to the back of
the charger. A DC cable clamp secures the DC cord to the terminal block using two Torx T10 screws. The DC
cable clamp is designed to provide optimum compression for cable diameters in the 9mm to 11mm range.
Care must be taken to prevent overtightening these screws during assembly. The recommended torque
for the DC cable clamp is 0.6Nm +/-6%.
A DC Terminal Block Cover is provided to protect the user from casual contact with the DC terminals. After
nal connections are made to the terminals, the cover is snapped into place and secured with one screw.
WARNING: Be very careful not to allow the battery voltage to be accidentally applied to the blade
terminals, as permanent damage to the charger will result.
