When using this terminal as a DC common, special considerations are required.
Be sure to consult with our sales representative.
Remark
Pay close attention when using 30~75W product for DC Common.
Buying DC reactor from the outside, it can not be installed with 30~75kW product. If you
want to use DC reactor of product, please purchase type of 30~75kW product mounted
with DC reactor. P1(+) terminal is at the Reactor’s front end while P2(+) terminal at its
back-end.
In the event of using such other DCR-mounted product for DC Common, you must use
P2(+) and N(-) terminals without fail. When using P1(+) and N(-) terminals for DC
Common, it may casue damage to the product.
Use for DC Common requires several considerations besides wiring. Therefore, in the
event it should be used for DC Common inevitably, be sure to contact our Sales
Department in advance.
Likewise, in the event of connecting with exterial braking unit, you must use P2(+) and
N(-) terminals without fail. When connecting with P1(+) and N(-) terminals, it may cause
damage to the product.
