Chapter 2: Meter Installation

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.
