Safety instructions

Overview

This chapter states the general safety instructions that must be

followed when installing and operating the FMBA-01 Modbus

Adapter 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.

WARNING! All electrical installation and maintenance work on the

drive should be carried out by qualified electricians.

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.
