ASME B20.1-2015 defines a qualified person as a person who, by possession of a
recognized degree or certificate of professional standing, or by extensive knowledge,
training, and experience, has successfully demonstrated his/her ability to solve
problems relating to the subject matter and work.
Personnel to carry out work at the brake must exclusively be qualified personnel
who - based upon their education, experience, instructions as well as knowledge
concerning relevant standards and provisions, accident prevention, regulations
and operating conditions - have been authorized by the person being responsible
for safety, to carry out the activities described in these instructions and who - when
doing so - are in a position to recognize possible risks early and to avoid them.

NOTICE
Safety Warnings
High Voltage! Installation or maintenance work may only be performed
when no power is available to the motor. Electric motors, electrical
brakes, and variable frequency drives contain potentially dangerous
high-voltage. Shut down the power at the circuit breaker or power
switch. Employees servicing or maintaining VRCs may be exposed to
death or serious personal injury if hazardous energy is not properly
controlled. De-energize any circuit before work is begun. Follow your facilities
procedures or OSHA lockout/tagout (LOTO) procedures anytime maintenance or
service is being performed on any electrical box or component.
Burn Hazard! Surfaces of motors and gear units may become hot
during operation or shortly after start-up. In some instances additional
protection against accidental contact may be necessary. Use caution to
avoid burns or serious injury!

Keep clear of unsupported platforms. Stay out of the area under a raised
platform. If a maintenance operation requires the carriage to remain in
the raised position, physically secure the carriage at the upper level using
adequately sized maintenance chains, maintenance pins, DeckLocks, or straps
with shackles around the drivebase that are capable of supporting the weight of
the carriage to provide additional safety.
