Be sure to wire correctly according to the terminal arrangement and wiring diagrams.
No. | Function | Terminal type |
---|---|---|
1 | 1, R, R | Phoenix terminal M3 screw with slotted head |
2 | 2, N, S | |
3 | 3, T, T | |
4 | Unused terminal (N.C.) | |
5 | Pulse output(+) | Phoenix terminal M2 screw with slotted head |
6 | Pulse output(-) | |
7 | RS-485(+) | |
8 | RS-485(-) | |
9 | RS-485(E) |
(Note): | RS-485 (E) terminal is not an SG (signal ground) terminal. Do not connect it to the grounding wire of a shielded cable. |

1) | Terminal fastening torque should be 0.5 to 0.6 N・m for No.1 to No.4 (M3 screw) and 0.22 to 0.25 N・m for No.5 to No.9 (M2 screw). |
---|---|
2) | Use wire with its cross section of 0.14~1.5mm2(AWG#26~14) for voltage input terminal (No.1, 2, 3), use wire with its cross section of 0.14~1.0mm2(AWG#26~16) for pulse output terminal (No.5, 6), use wire with its cross section of 0.3~1.0mm2(AWG#22~16) for communication terminal (No.7, 8, 9). When connecting 2 or more wires to communication terminal, use same wire with its cross section of 0.3 to 0.34mm2. |
3) | This has no built-in power switch, circuit breaker or fuse. Therefore it is necessary to install them in the circuit near this unit. |
4) | We recommend the below ferrules (terminals) for wiring. (We don’t recommend them when 2 or more wires are connected.) |
Terminal No. | Product number for Ferrule (PHOENIX CONTACT) |
---|---|
No.1 to No.4 (M3 screw) | AI 0.25-8YE AI 0.34-8TQ AI 0.5-8WH AI 0.75-8GY AI 1.0-8RD AI 1.5-8BK |
No.5 to No.9 (M2 screw) (When 1 wire is connected.) |
AI 0.25-8YE AI 0.34-8TQ AI 0.5-8WH |
5) | Use flame-resistant cable for each wiring. |

Please connect a breaker (3 to 15A) to the voltage input part for safety reasons and to protect the device. Grounding the secondary side of VT (Voltage transformer) and CT (Current transformer) is not necessary with low-voltage circuit.
|
|
Voltage transformer (VT) is needed when you measure a load with over rated input voltage (240V).Use VT, those secondary rating is 110V.
Grounding the secondary side of VT and CT is not necessary with low-voltage circuit.
