* If you combine a -7-Series SERVOPACK with a -V-Series Option Module,
the following -V-Series SERVOPACKs specifications must be used: a sur-
rounding air temperature of 0°C to 55°C and an altitude of 1,000 m max. Also,
the applicable range cannot be increased by derating.
External Power Supply for Control Circuits
For the DC power supply for the control signal I/O circuits (CN1 and CN8), use
a power supply device with double insulation or reinforced insulation.
Installation of a Short-Circuit Protection Element
Always use Fuses that comply with UL standards on the main circuit power
supply line.
Use either non-time delay fuses or semiconductor fuses.
Refer to 3.3 Molded-Case Circuit Breakers and Fuses on page 28 for informa-
tion on selecting fuse voltage and current ratings.
