Warnings and Notes

Danger:
• Make your ground connections first.
• Only a qualified personnel should install or replace this equipment.
• Confirm that the DC power source is OFF during installation. The power source should be a
safety extra-low voltage (SELV) source.
• Turn off power at the power source before you install or remove power cords.
• Before working on equipment that is connected to power, remove jewelry, such as rings,
necklaces, and watches. When metal objects are in contact with power and ground, serious burns
can occur or the objects can be welded to the terminals.
• You must use cables which meet local electrical code requirements.
• AC power cord set supplied with this product is strictly restricted for use with this product only.
The AC power cord set must not be used for any other purposes or any other products. When
applying power to the chassis, be sure to use the supplied AC power cord set, and make sure that
you do not use any other product's AC power cord set.
Japanese note:
• The unit should be connected to a DC branch circuit with a maximum 20A circuit breaker or fuse
which meets the requirements for branch circuit protection. A suitable disconnect device must be
provided in the DC branch, either a circuit breaker or switch that can be employed to disconnect
power to the system during servicing.
Caution:
• This product relies on the building's installation for short-circuit (over current) protection.
Ensure that a circuit breaker, or other equivalent means, rated 20A, is used in the building's AC
branch circuit for the current carrying conductors.
