IMPORTANT WARNING!
Prior to relocating the sterilizer to a new power source,
electrical phase rotation should be checked by a qualified
technician. Failure to verify phase rotation may cause
damage to the system and void the warranty.
208V 60 Hz Power
200V and 208V (Block 2)
For versions employing 208V, 60 Hz power, the sterilizer
requires a NEMA L21-20 five wire grounding twist lock
outlet attached to a dedicated 20 Amp 3 phase 208 Volt
circuit with separate neutral and ground conductors.
380 - 415V 50 Hz Power
380V, 398V and 415V (Block 2)
The sterilizer requires a five wire grounding outlet attached
to a dedicated 10 AMP, 3 phase, 380V circuit with separate
neutral and ground conductors.
Phase Rotation
The system requires CBA phase rotation. The phase
rotation is adjusted to match the system requirements at
installation.
