- IMMEDIATELY GET AWAY if you hear unusual sounds in the compressor. They can indicate that terminal pin ejection may be imminent. This may sound like electrical arcing (sizzling, sputtering or popping). However, terminal venting may still occur even if you do not hear any unusual sounds. © 2024 Copeland LP www.copeland.com... - Page 5 POE lubricant. Handle POE oil with care. Refer to the Safety Data Sheet (SDS) for further details. • Before energizing the system: 1. Securely fasten the protective terminal cover or molded plug to the compressor, and 2. Check that the compressor is properly grounded per the applicable system and compressor requirements. © 2024 Copeland LP www.copeland.com...
