ground, so the user may elect to Ground either + or - terminal to suit the customer’s
use.
Before connecting hot lines to the Terminal Block of –48VDC, 24VDC or
125VDC, always use a digital voltmeter to measure the output voltage of the power
supply and determine the lead which is more “+ve potential”. The more “+ve” voltage
lead from 48V or –48V supply must be connected to the post labeled “+”.
An ON-OFF manual switch is optional for DC power. This can be used to cut
off power connections and as a RESET for the Magnum 6K32T & 6K32TRC Switch.
