The meter can be powered from an AC or DC power source.
• L1 and L2 are non-polarized. If using an AC power supply with neutral, connect neutral to the meter’s L2 terminal.
• Always use a fuse on L1. Fuse L2 when connecting an ungrounded neutral to the control power.
• If using a control power transformer, fuse both primary and secondary sides of the transformer.
• The fuses / circuit breakers must be rated for the installation voltage and sized for the available fault current.
