CAUTION

1. If a circuit protector is shared by several drive units, the circuit protector may

not activate when a short-circuit fault occurs in a small capacity drive unit. This
is dangerous, so never share the circuit protector by several drive units.
Always install the circuit protector for each drive unit.

2. If the control power (CN22) must be protected, select according to the section

"5-4 Selection of control power supply".
