3.1.2 Inspection
 DANGER
 
◆
The user is responsible for ensuring that the motor, AC drive, and 
other components are installed and connected in accordance with the 
recognized technical rules in the country of installation and with other 
applicable regional regulations. Special attention should be paid to cable 
dimensions, fuses, grounding, shutdown, disconnection, and overcurrent 
protection.
 
◆
If an item of protective gear trips in a branch circuit, a leakage current may 
have been disconnected. To reduce the risk of re or an electric shock, the 
current-carrying parts of the AC drive and other components in the cabinet 
should be inspected and damaged parts should be replaced. When an 
item of protective gear trips, the cause of the trip must be identied and 
rectied.
3.1.3 General

electricity. Wear a grounded wrist strap when operating the circuit board. 
Do not touch the circuit board unless necessary.
