RMBA-01 User’s manual iii
Safety instructions
Overview This chapter states the general safety instructions that
must be followed when installing and operating the
RMBA-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.
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.
