For 100-240 VAC rated equipment, an appropriately rated circuit breaker must
be installed.
Use only #16 gage copper wiring when connecting terminal blocks.
A circuit breaker is not required for 12, 24 or 48 VDC rated equipment.
Power input terminals have reverse polarity protection for 12, 24 and 48 VDC
rated equipment.
Equipment must be installed according to applicable local wiring codes and
standards.
