● Core: These units contain a wide range of components that achieve common
requirements for Medium Voltage drive performance:
– Integral isolation transformer
– NEMA 1 ventilated (IP31) enclosure
– Multiple power and amperage frame sizes
– Multiple input voltages and frequencies
– ASA 61 gray enclosure paint
– Keypad, E-Stop
– Blower for forced air cooling
– NEMA hole pattern medium voltage connections
● Pre-Engineered: These option packages allow customers to specify a variety of add-ons
to the flexible Core unit without an increase in footprint (see list below):
– Electrostatic transformer shield
– Distribution class surge arresters
– Mechanical cell bypass
– Redundant blower (or N+1)
– Blower cage with duct interface
– 24 V DC Control
– Encoder power supply for CLVC
– EMC auxiliary voltage filter
– MPM
– Space heater
– Mechanical door key interlocks
– Auxiliary voltage isolation transformers
– Industry standard communications (single or dual networks)
– Agency approval (UL, CSA, CE)
● Custom: These selections are not readily available as pre-engineered options for the
GenIV; however, our Siemens engineering staff has experience in designing these
configurations in transition cabinets as an add-on to the drive line-up (see list below):
– Synchronous transfer output reactors
– Synchronous motor exciters and field supplies
– RTD scanners
– Motor encoders
– Switchgear and full/reduced voltage motor starters
– Power quality and equipment
