.6.3 Changing the control logic
The input signals are set to sink
logic for the Japanese and NA
version, and to source logic for
the EC version.
To change the control logic, the
connector under the setting dial
must be moved to the other
position.
Change the connector position
using tweezers, a pair of long-
nose pliers etc.
Change the connector position
before switching power on.
NA and Japanese version
EC version
CAUTION
• Make sure that the front cover is installed securely.
• The front cover is fitted with the capacity plate and the inverter unit with the rating
plate. Since these plates have the same serial numbers, always replace the
removed cover onto the original inverter.
• The sink-source logic change-over connector must be fitted in only one of those
positions. If it is fitted in both positions at the same time, the inverter may be
damaged.
