Dimensions and connectors on the power supplies
The connectors on the top of the bulk power supplies are:
120/230 VAC input
: Protective earth
24 VDC output
- ENA: Output enable. The wire from ENA to ENA RTN is connected at the factory.
- V OUT: DC voltage output (+)
- V OUT: DC voltage output (+)
- RTN: DC voltage return (-)
- RTN: DC voltage return (-)
- SHARE: This connection is required for redundancy and load-sharing applications.
- ENA RTN: Output enable return. The wire from ENA to ENA RTN is connected at the factory.
Alarm relay contacts
The alarm relay contacts are on the bottom of the bulk power supplies:
