Ingersoll Rand Starter Motors for Solar Turbines - ATEX Product Safety Information (10550663)
This manual sets out the ATEX product safety conditions for Ingersoll Rand starter motors supplied for Solar turbines and used in potentially explosive atmospheres. It explains the II 3 GD c IIB 71°C X marking, the special conditions for installation, operation and maintenance, the measured maximum surface temperature, and the recommended full-rebuild interval in start cycles for each covered model. It closes with the safety signal words and a Declaration of Conformity listing the models and standards; it is meant for turbine packagers, installers and maintenance staff.

Frequently Asked Questions
What does the ATEX marking II 3 GD c IIB 71°C X mean on these starter motors?
Per the manual: Group II non-mine equipment, Category 3, evaluated for gas (G) and dust (D) atmospheres, protection by constructional safety (c), gas group IIB, a 71°C maximum surface temperature, and X for special conditions that must be followed.
How often should an ATEX starter motor for a Solar turbine be rebuilt?
The manual recommends a complete rebuild every 1000, 2000 or 4000 start cycles depending on the model; for example, the TS1425 and ST925G-RC350 are listed at 4000 start cycles.
What surface temperature was measured on these starter motors?
A maximum of 71°C at 21°C ambient, with the motor at free speed on 90 psig (6.2 bar) inlet air.
Can these ATEX starters be used on equipment other than Solar turbines?
No. The document states the ATEX designation applies only to use on Solar turbines and the product is not for non-Solar applications.
What grounding is required for these starter motors?
The manual requires the motor to be grounded at all times with a resistance to earth below 10000 Ohms to avoid electrostatic discharge.
