DANGER- When terminals P (+) and N (-) of
the inverter are not used, leave terminals
open. If P(+) is connected to N (-) the bus
voltage will be shorted, or if braking resistor is
connected directly, the resistor can cause
fire.
d. Auxiliary contacts 1 and 2 of the braking
unit are polarity sensitive. To connect the
braking unit, refer to the "TECO Inverter
Speecon Braking Unit Manual”.

7. Inverter ground terminal
To ensure safety and noise reduction, always bond the inverter ground terminal. Also,
metal frames of electrical equipment must be grounded as specified in applicable codes
The connection procedure is as follows:
a. Ground all metal frames and chassis to a ground terminal (Ground resistance: ≤10Ω).
b. In accordance with applicable codes, use a suitable ground cable to connect the inverter
system to ground.
8. Placement of connector (CN UX) for inverters 40HP/CT, 50HP/VT and higher.
When an inverter of 40HP or higher is connected to an input voltage listed in Table 2-3-2,
disconnect the auxiliary power connector CN UX from U1 and connect to U2.
(Refer to Fig. 2-3-7)
Table 2-3-2 Main Input Voltage Requiring Auxiliary Power Connector Change
Frequency [Hz] Input voltage range [VAC]
50 380 - 398
60 380 - 430
9. Placement of fan power connector (CN RXTX) for inverters 40HP/CT, 50HP/VT or higher.
An inverter of 40HP/CT, 50HP/VT or greater uses an AC cooling fan. When the inverter is being
operated with DC Input power, the fan must still be energized from an AC power
source. To do this, position the fan connector (CN RTXT) as shown in Fig. 2-3-9
and provide AC voltage to auxiliary input terminals R0 and T0. For the (CN RTXT)
connector placement method, see Fig. 2-3-7.
Note: When shipped, the fan connector (CN RXTX) is connected to L1/R-L3/T. Do not change the
connector position unless DC power is being used.
