MICROMASTER 420 Operating Instructions

6SE6400-5AA00-0BP0

The control, power supply and motor leads must be laid separately. Do not feed them
through the same cable conduit/trunking. Never use high voltage insulation test
equipment on cables connected to the inverter.

All inverters will operate at full specification with cable lengths up to 50 m screened or
100 m unscreened.

♦  Isolate the mains electrical supply before making or changing connections to the

unit.

♦  Ensure that the motor is configured for the correct supply voltage: single / three-

phase 230 V MICROMASTERS must not be connected to a 400 V three-phase
supply.

♦  When synchronous machines are connected or when coupling several motors in

parallel, the inverter must be operated with voltage/frequency control characteristic
(P1300 = 0, 2 or 3).

After connecting the power and motor cables to the proper terminals, make sure that the
covers have been replaced properly before supplying power to the unit!

♦  Ensure that the appropriate circuit-breakers/fuses with the specified current rating

are connected between the power supply and inverter (see table on Page 93).

♦  Use Class 1 60/75

o

C copper wire only (for UL compliance). Tightening torque for

the power terminals is 1.1 Nm.

♦  To tighten up the power terminal screws use a 4 - 5 mm cross-tip screwdriver.

The procedure for accessing the power and motor terminals on the MICROMASTER 420
Inverter is illustrated in Appendices B and C. Please also refer to the photographs
showing the Power Terminal connections and the Control Terminal connections on the
inside of the back cover of this manual.

When the covers have been removed to reveal the terminals, connect the power and
motor connections as shown on the next page.
