Installation Guidelines AC wiring specifications: If an AC wiring extension is required, use the same type of AC wiring that is used in the cabinet. RS485 wiring specifications: Cable type: Min. 3-wire shielded twisted pair (a 4-wire cable may be used) Wire cross-section area: 0.2-1 mm² (a CAT6 cable may be used) NOTE If using RS485 cable longer than 10 meters in areas where there is a risk of induced voltage surges by lightning, it is recommend to use surge protection devices. If grounded metal conduits are used for routing the communication wires, there is no need for a lightning protection device. Additional Guidelines: The inline meter is considered “permanently connected equipment” and requires a disconnect means (circuit breaker, switch, or disconnect) and overcurrent protection (fuse or circuit breaker). The rating of any switches, disconnects, fuses, and/or circuit breakers is determined by the inline meter's current rating, the mains voltage, and the current interruption rating required. The switch, disconnect, or circuit breaker must be located near the inline meter and be easily operated. Use grouped circuit breakers when monitoring more than one line. The circuit breakers or fuses must protect the mains terminals labeled L1, L2, and L3. In the rare case in which neutral has overcurrent protection, the overcurrent protection device must interrupt both neutral and the ungrounded conductors simultaneously. The circuit protection / disconnect system must meet IEC 60947-1 and IEC 60947-3, as well as all national and local electrical codes. Chapter 2: Meter Installation     15 Inline Energy Meter with SolarEdge Energy Net Communications

NOTE Make sure the inline meter's rating is within maximum permitted current limitations. In export/import applications, check that the rating of the main circuit breaker is within maximum permitted current limitations. Mounting the Inline Meter To mount the inline meter on a DIN rail: The inline meter is designed for permanent installation in indoor locations. It is intended for installation in switch cabinets or in small-installation distributors on a 35 mm mounting rail as per DIN EN 60715. Mount the inline meter on the DIN rail as shown in the figure below. Fit the slot on the back of the meter over the DIN rail (see steps 1 and 2), and secure it in place on the DIN rail using the latching mechanism at the bottom of the meter. Figure 8: Mounting the inline meter on a DIN-rail To detach the inline meter from the DIN rail:  1. Disconnect all AC wires and RS485 cable (if connected), or Energy Net antenna.  2. Detach the meter from the DIN rail by releasing the lever at the bottom of the meter, and then separating it from the rail.
