screw driver, and insert the wire.
Wire removal
앫
Pull the wire with pushing the open/close button all the way down firmly with a flathead screwdriver.
4.4.4 Wiring Instructions
앫
Terminals PC, 5, and SE are all common terminals (0 V) for I/O signals and are isolated from each other. Avoid connecting the
terminal PC and 5 and the terminal SE and 5 (ground). Terminal PC is a common terminal for the contact input terminals (STF,
STR, RH, RM and RL).
앫
Use shielded or twisted cables for connection to the control circuit terminals and run them away from the main and power circuits
(including the 230 V relay sequence circuit).
앫
Use two or more parallel micro-signal contacts or twin
contacts to prevent a contact faults when using contact inputs
since the control circuit input signals are micro-currents.
앫
Do not apply a voltage to the contact input terminals (e. g. STF)
of the control circuit.
앫
Always apply a voltage to the alarm output terminals (A, B, C)
via a relay coil, lamp, etc. In no way must a voltage be short-
circuited by these relay contacts.
앫
It is recommended to use the cables of 0.3mm² to 0.75mm² gauge for connection to the control circuit terminals.
The wiring length should be 30 m maximum.
앫
The level of the control signals can be switched over between positive (SOURCE) and negative (SINK) logic. The input signals are
set to source logic when shipped from the factory. To change the control logic, the jumper connector above the control circuit
terminal block must bemoved to the other position.
앫
Do not short terminal PC and SD. Inverter may be damaged.
CAUTION
앫
When using a stranded wire without a bar terminal, twist enough to avoid short circuit with a nearby terminals or wires.
앫
Place the flathead screwdriver vertical to the open/close button. In case the blade tip slips, it may cause to damage of inverter
or injury.
CAUTION
앫
Use a small flathead screwdriver (Tip thickness: 0.4 mm/tip width: 2.5 mm, such as SZF 0-0,4x2,5 (Phoenix Contact Co., Ltd.)). If
a flathead screwdriver with a narrow tip is used, terminal block may be damaged.
앫
Place the flathead screwdriver vertical to the open/close button. In case the blade tip slips, it may cause to damage of inverter
or injury.
