Note:
Fuses listed in the table below are the standard fuses that are factory installed,
Note
unless otherwise specified.
Fuse ratings may differ due to:
• Unique customer-specific configurations or requirements, or
• Product specification changes
When changing fuses, always check original fuse for value and type, and
ensure the replacement fuse you use is of that value and type. Do not assume
that installed fuse is of the correct value.
