Commissioning
7.3 Switching on
● If it runs perfectly, connect a load. Check that it runs smoothly, and read off and
document the values for voltage, current and power. As far as possible, read off and
document the corresponding values for the driven machine as well.
● Monitor and document the temperatures of the bearings, windings, etc. until the system
reaches a steady state, in as much as this is possible with the available measuring
instruments.
Measures to take when commissioning explosion-proof machines
After installation or inspections, the following measures are recommended for normal start-
up of the machines:
● Start the machine without a load; to do this, close the motor starter protector and do not
switch the machine off prematurely.
● You should limit how often you switch the machine off while it is starting up and still
running at a slow speed, for checking the direction of rotation or the required dimensions,
for example.
● Allow machines to reach a standstill before switching them back on.
