Siemens SINAMICS SL150 - Cooling System Test; Static Pressure Test

3.3 Cooling system test
3.3.1 Static pressure test
Fundamentals
Tests are performed according to IEC 61800-5-1 and DIN EN 805.
The drive cooling system is checked for leaks and pressure drop for one hour.
Test procedure
1. The cooling system is filled with coolant and the valves in the supply and return lines are
closed.
2. With the valves closed, pressure is increased to a test pressure of p
t
and is controlled for the
next 10 min.
3. After a total of 30 min, pressure p
1
is measured.
4. After a total of 60 min, pressure p
2
is measured.

Result
The test is passed if the differential pressure is ≤ 0.4 bar and no leaks have occurred in the
cooling system.
