6.1 Configuring the FRENIC-Mini
This section lists the names and features of peripheral equipment and options for the FRENIC-Mini series
of inverters and includes a configuration example for reference. Refer to Figure 6.1 for a quick overview
of available options.

6.2 Selecting Wires and Crimp Terminals
This section contains information needed to select wires for connecting the inverter to commercial power
lines, motor or any of the optional/peripheral equipment. The level of electric noise issued from the
inverter or received by the inverter from external sources may vary depending upon wiring and routing. To
solve such noise-related problems, refer to Appendix A "Advantageous Use of Inverters (Notes on
electrical noise)."
Select wires that satisfy the following requirements:
-
Sufficient capacity to flow the rated average current (allowable current capacity).
- Protective device coordination with an overcurrent circuit breaker such as an MCCB in the
overcurrent zone for overcurrent protection.
-
Voltage loss due to the wire length is within the allowable range.
-
Suitable for the type and size of terminals of the optional equipment to be used.
Recommended wires are listed below. Use these wires unless otherwise specified.
600V class of vinyl-insulated wires (IV wires)
Use this class of wire for the power circuits. This class of wire is hard to twist, so using it for the control
signal circuits is not recommended. Maximum ambient temperature for this wire is 60 C (140 F).
600V heat-resistant PVC insulated wires or 600V polyethylene insulated wires (HIV wires)
As wires in this class are smaller in diameter and more flexible than IV wires and can be used at a higher
ambient temperature 75 C (167 F), they can be used for both of the main power and control signal circuits.
To use this class of wire for the control circuits, you need to correctly twist the wires and keep the wiring
length for equipment being connected as short as possible.
600V cross-linked polyethylene-insulated wires (FSLC wires)
Use this class of wire mainly for power and grounding circuits. These wires are smaller in diameter and
more flexible than those of the IV and HIV classes of wires, meaning that these wires can be used to save
on space and increase operation efficiency of your power system, even in high temperature environments.
The maximum allowable ambient temperature for this class of wires is 90 C (194 F). The (Boardlex) wire
range available from Furukawa Electric Co., Ltd. satisfies these requirements.
Shielded-Twisted cables for internal wiring of electronic/electric equipment
Use this category of cables for the control circuits of the inverter so as to prevent the signal lines from
being affected by noise from external sources, including the power input/output lines of the inverter
themselves. Even if the signal lines are inside the power control cabinet, always use this category of cables
when the length of wiring is longer than normal. Cables satisfying these requirements are the Furukawa's
BEAMEX S shielded cables of the XEBV and XEWV ranges. 6.2 Selecting Wires and Crimp Terminals

Currents Flowing across the Inverter Terminals
Table 6.1 summarizes average (effective) electric currents flowing across the terminals of each inverter
model for ease of reference when selecting peripheral equipment, options and electric wires for each
inverter--including supplied power voltage and applicable motor rating.
