Please use shielded twisted-pair cable when analog signal is inputted externally. It’s recommended to use 0.5 - 1 mm 2 cable as control circuit cable. Terminal block of EM600 inverter shall be through control circuit connection terminal. Please use a PH0 cross screwdriver for installation with tightening torque of 0.5 N.m. 3.3.10 Attentions for Control Circuit Wiring Separate control circuit cable from other cable. Separate cable of control circuit terminals EA, EB, EC, Y1 and Y2 from cable of other control circuit terminals. To prevent malfunctions caused by interference, use shielded twisted-pair cable for control circuit, with the wiring distance less than 50m.
Wrap shield net with insulating tape to prevent the shield net from contacting with other signal cable and housing of device. It’s not allowed to contact various ports or components without ESD measures. 43 Host Controller 上RS位48机5 RCSo4m8m5通un讯ica接tio口n Interface +端+ -端- GND +端+ -端-
