1) Use ring terminals with insulating sleeves as shown in the fi gure to connect to
the terminal block.
2) Securely clamp the ring terminals to the cables using an appropriate tool so that
the cables do not come loose.
3) Use the specifi ed cables, connect them securely, and fasten them so that there is
no stress placed on the terminals.
