Summary of Contents for Mitsubishi 700 Series

Page 1 This Instruction Manual (Basic) is intended for users who "just want to run the inverter". If you are going to utilize functions and performance, refer to the Instruction Manual (Applied) [IB-0600366ENG]. The Instruction Manual (Applied) is separately available from where you purchased the inverter or your Mitsubishi sales representative.
Page 2 This Instruction Manual (Basic) provides handling information and precautions for use of the equipment. Please forward this Instruction Manual (Basic) to the end user. 1. Electric Shock Prevention This section is specifically about safety matters WARNING Do not attempt to install, operate, maintain or inspect the While power is ON or when the inverter is running, do not inverter until you have read through the Instruction Manual open the front cover.
Page 3 3.Injury Prevention (3) Trial run CAUTION CAUTION The voltage applied to each terminal must be the ones Before starting operation, each parameter must be specified in the Instruction Manual. Otherwise burst, confirmed and adjusted. A failure to do so may cause damage, etc.
Page 4 (5) Emergency stop CAUTION A safety backup such as an emergency brake must be provided to prevent hazardous condition to the machine and equipment in case of inverter failure. When the breaker on the inverter input side trips, the wiring must be checked for fault (short circuit), and internal parts of the inverter for a damage, etc.

Page 37: Precautions For Use Of The Inverter
Precautions for use of the inverter Precautions for use of the inverter The FR-D700 series is a highly reliable product, but incorrect peripheral circuit making or operation/handling method may shorten the product life or damage the product. Before starting operation, always recheck the following items. (1) Use crimping terminals with insulation sleeve to wire the power supply and motor.

It gives an indication of replacement time. The life alarm output can be used as a guideline for life judgement.
Page 129 Inspection items (2) Measuring method of life of the main circuit capacitor If the value of capacitor capacity measured before shipment is considered as 100%, Pr. 255 bit1 is turned ON when the measured value falls below 85%. Measure the capacitor capacity according to the following procedure and check the deterioration level of the capacitor capacity.
