When using a single wire or stranded wires without a blade terminal, push the open/close button all the way down with a flathead screwdriver, and insert the wire. 2 3 Open/close button 5 Flathead screwdriver 5 6 NOTE • When using stranded wires without a blade terminal, twist enough to avoid short circuit with a nearby terminals or wires. 7 • Place the flathead screwdriver vertical to the open/close button. In case the blade tip slips, it may cause an inverter damage or injury. 8 Wire removal Pull the wire while pushing the open/close button all the way down firmly with a flathead screwdriver.
9 Open/close button 10 Flathead screwdriver NOTE • Pulling out the wire forcefully without pushing the open/close button all the way down may damage the terminal block. • Use a small flathead screwdriver (tip thickness: 0.4 mm / tip width: 2.5 mm). • Place the flathead screwdriver vertical to the open/close button. In case the blade tip slips, it may cause an inverter damage If a flathead screwdriver with a narrow tip is used, terminal block may be damaged. or injury. Common terminals of the control circuit (SD, PC, 5) • Terminal SD (sink logic) and terminal 5 are common terminals (0 V) for input signals (all common terminals are isolated from each other).
Do not earth (ground) these terminals. Avoid connecting the terminal SD with terminal 5 (when sink logic is selected). • In the sink logic, terminal SD is a common terminal for the contact input terminals (STF, STR, RH, RM, RL). The open collector circuit is isolated from the internal control circuit by photocoupler. • In the source logic, terminal PC is a common terminal for the contact input terminals (STF, STR, RH, RM, RL). The open collector circuit is isolated from the internal control circuit by photocoupler. 39 2.
