Mechanical Installation
Manual Motor Starters
Provides 3-phase power for electric blowers often required
for larger motors. Power for the starters is provided from
the load side of any supplied contactor, circuit breaker, or
disconnect switch. Power is fused before each motor
starter, and is off when the incoming power to the
3 3
frequency converter is off. Up to 2 starters are allowed
(one if a 30 A, fuse-protected circuit is ordered). Integrated
into the frequency converter's safe-stop circuit.
Unit features include:
•
Operation switch (on/off)
•
Short-circuit and overload protection with test
function
•
Manual reset function
30 A, Fuse-Protected Terminals
•
3-phase power matching incoming mains voltage
for powering auxiliary customer equipment
•
Not available if 2 manual motor starters are
selected
•
Terminals are off when the incoming power to
the frequency converter is off
•
Power for the fused protected terminals will be
provided from the load side of any supplied
contactor, circuit breaker, or disconnect switch.
24 V DC Power Supply
•
5 A, 120 W, 24 V DC
•
Protected against output over-current, overload,
short circuits, and over-temperature
•
For powering customer-supplied accessory
devices such as sensors, PLC I/O, contactors,
temperature probes, indicator lights, and/or other
electronic hardware
•
Diagnostics include a dry DC-ok contact, a green
DC-ok LED, and a red overload LED
External Temperature Monitoring
Designed for monitoring temperatures of external system
components, such as the motor windings and/or bearings.
Includes five universal input modules. The modules are
integrated into the frequency converter's safe-stop circuit
and can be monitored via a fieldbus network (requires the
purchase of a separate module/bus coupler).
Universal inputs (5)
Signal types:
•
RTD inputs (including PT100), 3-wire or 4-wire
•
Thermocouple
•
Analog current or analog voltage
Additional features:
•
One universal output, configurable for analog
voltage or analog current
•
2 output relays (N.O.)
