parallel resistors, 200 Hp or more parallel braking units.
(7) Ground terminal
The grounding connector should be sized in accordance
with the NEC or Canadian Electrical Code. The connec-
tion should be made by a UL listed or CSA certified
closed-loop termianl connector sized for the wire gauge
involved. The connector is to be fixed using the crimp tool
specified by the connector manufacturer.
(8) Auxiliary power switching connector (CN UX) (for
drives of 40 Hp or more)
When a drive of 40 Hp or more requires main circuit
power voltage as listed below, disconnect the auxiliary
power switching connector CN UX from U1 and connect
to U2. For the switching method, see Fig. 2-3-6.

CAUTION
• Check that the number of phases and rated
voltage match those of the AC power supply.
• Do not connect the AC power supply to the
output terminals (U, V, W). Injury may result.
• Do not directly connect a braking resistor to
the DC terminals (P[+] and N[-]). Fire may
result.
The switching connectors are mounted on the power PCB
above the control PCB as shown on the right.
Note: To remove a connector, unlock the connector (using
the locking mechanism) and pull. To install, firmly push the
connector until it click locks.
