Magnum 6K32F/FR/FC/FRC Managed Switch Installation and User Guide (05/08)
Note: The GND should be hooked up first. The 6K32F Series units have a floating
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 "+".
The connection procedure is straightforward. Simply connect the DC leads to
the Switch's power terminals, positive (+) and negative (-) screws. Ensure that each lead
is securely tightened.
The 24VDC and 125VDC terminal block on Magnum 6K32F Series is similar
to that described in the –48VDC information above.

3. Use only with Listed 10 A circuit breaker provided in building installation.
4. "Complies with FDA radiation performance standards, 21 CFR subchapter J."
or equivalent.
5. Fastening torque of the lugs on the terminal block: 9 inch pound max.
6. Centralized DC Power Source cable securement, use at least four Minimum 14
AWG cable ties to secure the cable to the rack at least 4 inches apart with the
first one located within 6 inches of the terminal block.
