[. . . ] Understand the following details (indications and symbols) before reading the body text, and follow the instructions. ⷠAfter the installation work has been completed, perform a trial operation to check for any problems. [. . . ] Power supply Power consumption Operating temperature/humidity Storage temperature Chassis material Dimensions Mass Input type Input points Power meter input Input registance Input "ON" current Input pulse condition 220V - 240VAC, 50/60Hz 4W 0 to 40 °C, 10 to 90% RH -20 to +60 °C Galvanized sheet metal 0. Use the following wiring materials to connect the signal lines and power lines. Line Type 1 For RS-485 Wire size Length Type 2 For connection to power meter Wire size Length 3 For power Type Wire size H07 RN-F or 245IEC66 0. There are five installation methods for this relay interface as shown below: surface mount and wall mounts. Place where there is a TV set or radio within one meter · A side space for connecting through cable inlets and an upper space for maintenance must be reserved before installation. Connect power cables, earth wires, and communication cables to the specified terminals on the terminal block. To connect 2 cables, change the preset cable clamp to the provided one and fix the cables with the cable clamp as shown in the figure. Touch Screen Controller or other central controller Power meter Secure each cable with a cable clamp. Power supply 220-240VAC (50/60Hz) Length of stripped power cable When inserting two RS-485 communication cables into a single terminal for connection to another interface, crimp them using the attached pin terminal. This appliance must be connected to the main power supply by a circuit breaker or switch with a contact separation of at least 3mm. The following describes a connection example of Energy Monitoring Relay Interface. When they are connected to inappropriate input terminal, the unit may not operate properly. [. . . ] In the test mode, when the external inputs connected to the input terminals DI-1 to DI-8 are ON, the respective LEDs will goes on so you can confirm the connection. Confirming procedure: Set the operation mode switch SW2 to "3", and push the reset switch SW6 to enter the test mode. [. . . ]
