NOTICE
Damage to Equipment. When you use the drive with a non-grounding, high-resistance
grounding, or asymmetric-grounding network, put the EMC Filter screw or screws in the OFF position to disable
the built-in EMC filter. If you do not disable the built-in EMC filter, it will cause damage to the drive.
If you lose an EMC filter switch screw, use Table 1.9 to find the correct replacement screw and
install the new screw with the correct tightening torque.
NOTICE
Only use the screws specified in this manual. If you use screws that are not approved, it
can cause damage to the drive.
