(５) Connecting Currently Used Cables (When the Power-factor Improvement DC Reactor Is Not Used)
１．Remove the terminal block cover ①. There are cables connected to the currently used servo
amplifier. Remove them and connect them to the terminal block of Renewal Kit. (Signal names are
different. See Fig. 1 to check the signal names before connecting the cables.)
* If you are going to use the power-factor improvement DC reactor, you need to follow different
steps to make connections. See paragraph (6).
* Use caution not to incorrectly
connect the currently used cables.
The amplifier will be broken if you make
an incorrect connection.
２． Attach the terminal block cover ① on
the terminal block of Renewal Kit.
３．Connect the currently used grounding
wire ② to the grounding terminal on
TE bracket 2 ③.
