Wiring Descriptions
250 mA fuse:
※
Either positive or negative charge can be used on L1/+ and L2/-. When using a neutral wire for AC power,
you need to connect the neutral wire to the L2/-.
※
Always use a fuse on L1/+. When using an ungrounded neutral wire to connect to the power, use a fuse on
L2/-. If you are using a Power Transformer (PT) or a Current Transformer (CT), use fuses on the primary
and secondary windings.
※
The rated voltage / current of the fuse, breaker, and device should be the same to prevent damage to
electrical equipment or other property.
