*1 For IP20 protection, use wires that are in the range of applicable gauges.
*2 Remove insulation from the ends of wires to expose the length of wire shown.
*3 For wire gauges more than 30 mm
*4 Install an RCM/RCD with this wire gauge to maintain compliance with IEC/EN 61800-5-1:2007.
*5 Terminals - and +1 have two screws. The Recommended Gauge is the wire gauge for one terminal.
*6 A junction terminal is necessary to connect a braking resistor unit (LKEB-series) to terminals B1 and B2.

Connect a Fuse to the Input Side (Primary Side)
The drive circuit protection must comply with IEC/EN 61800-5-1:2007 for protection against a short circuit in the
internal circuitry. The manufacturer recommends connecting semiconductor protection fuses on the input side for
branch circuit protection.
WARNING! Electrical Shock Hazard. Do not immediately energize the drive or operate peripheral devices after the drive blows
a fuse or trips an RCM/RCD. Wait for the time specified on the warning label at a minimum and make sure that all indicators are
OFF. Then check the wiring and peripheral device ratings to find the cause of the problem. Contact the manufacturer before
energizing the drive or peripheral devices if the cause is not known. Failure to obey can cause death or serious injury and
damage to the drive.
*1 The manufacturer recommends a fuse with a large rated current for applications with repeated loads.
