Installation Safety Precautions (cont'd)
14) Do not connect control circuit terminal block return connections marked CC to
inverter earth ground terminals marked GND(E). See
Standard Connection
Diagrams page 4-1 and Terminal Connections and Functions page 5-3.
15) If a secondary Magnetic Contactor (MC) is used between the inverter output
and the load, it should be interlocked so the ST-CC terminals are disconnected
before the output contactor is opened. If the output contactor is used for bypass
operation, it must also be interlocked so that commercial power is never applied
to the inverter output terminals (U,V,W).
16) Power factor improvement capacitors or surge absorbers must not be installed
on the inverter's output.
17) Only qualified personnel should install this equipment.
Operating Safety Precautions
1) Do not power up the inverter until this entire operation manual is reviewed.
2) The input voltage must be within +/-10% of the specified input voltage. Voltages
outside of this permissible tolerance range may cause internal protection
devices to turn on or can cause damage to the unit. Also, the input frequency
should be within +/-2 Hz of the specified input frequency.
3) Do not use this inverter with a motor whose rated input is greater than the rated
inverter output.
4) This inverter is designed to operate NEMA B motors. Consult the factory before
using the inverter for special applications such as an explosion proof motor or
one with a repetitive type piston load.
5)
Do not touch any internal part with power applied to the inverter; first remove
the power supply from the drive and wait until charge LED (see page 5-1 for location)
is no longer illuminated. Charged capacitors can present a hazard even if source
power is removed.

7) Do not apply commercial power to the output terminals T1 (U), T2 (V), or T3
(W) even if the inverter source power is off. Disconnect the inverter from the
motor before megging or applying bypass voltage to the motor.
