NOTE

Attach the accompanying gasket around the panel

cut-out to prevent oil and dust from getting into it.

Reinforce the right and left sides of the panel

cut-out in the power magnetics cabinet by using

fittings such as angles to maintain satisfactory

contact between the power magnetics cabinet and

the amplifier.

NOTE

1 Always install the circuit breakers, magnetic

contactor, and AC line filter.

2 To protect the equipment from lightning surge

voltages, install a lightning surge absorber across

each pair of power lines and across each power line

and the grounding line at the power inlet of the

power magnetics cabinet.

WARNING

Defects, such as a loose screw and an incorrectly

inserted connector, can lead to a motor malfunction,

excessive heat generation, and a ground fault.

Exercise adequate care in installing servo

amplifiers.

A loose screw (or, if a connector is used, a loose

connector contact or an incorrect connector

pin-to-cable connection) on high-current carrying

power supply wires or motor power wires can lead

to fire. Exercise adequate care in wiring.
