[UL Standard, Low Voltage Directive]
Ensure that the installation conditions described in the "ALPHA7 Series" servo
amplifier instruction manual and user's manual are satisfied.
[EMC Directive]
Ensure that the installation conditions described in the "ALPHA7 Series" servo
amplifier instruction manual and user's manual are satisfied.
Compatibility with the EMC Directive may vary depending on conditions such as
the actual product configuration and wiring, and therefore compatibility should
be checked on the customer's machine at which EMC countermeasures have
