Safety instructions

Overview This chapter states the general safety instructions that

must be followed when installing and operating the

RAIO-01 Analogue I/O Extension module.

The material in this chapter must be studied before

attempting any work on, or with, the unit.

In addition to the safety instructions given below, read

the complete safety instructions of the specific drive you

are working on.

General safety

instructions

WARNING! All electrical installation and maintenance

work on the drive should be carried out by qualified

electricians only.

The drive and adjoining equipment must be properly

earthed.

Do not attempt any work on a powered drive. After

switching off the mains, always allow the intermediate

circuit capacitors 5 minutes to discharge before working

on the frequency converter, the motor or the motor

cable. It is good practice to check (with a voltage

indicating instrument) that the drive is in fact discharged

before beginning work.

The motor cable terminals of the drive are at a

dangerously high voltage when mains power is applied,

regardless of motor operation.

There can be dangerous voltages inside the drive from

external control circuits even when the drive mains

power is shut off. Exercise appropriate care when

working on the unit. Neglecting these instructions can

cause physical injury or death.
