Power Up Sequence

There is no power switch. Supply power to the unit only after it is mounted.

CAUTION: To prevent electrical shock, make sure the switch is grounded

properly. If you do not ground your equipment correctly, excessive emissions

can result. Use a qualified electrician to ensure that the power cables meet

your local electrical requirements.

NOTE: A US AC power cable is included in the shipping container for powering

up an AC power supply. All other power cables must be ordered separately.

S25N

The S25N has two AC receptacles in the PSU side of the unit. The system can

use either power source independently, or act in load-sharing mode.

S25V

The S25V has both an AC (3-prong plug receptacle) and a DC (-48V terminal-

type) connection on the PSU side of the unit. Each power source can be used

independently or in load-sharing combination. In other words, you have three

options for providing power to the switch — AC only, DC only, or using both

AC and DC sources.

•

To use AC only, connect the supplied AC power cord first to the switch

(receptacle on the right as you face the PSU side of the unit) and then to the

power source. Connect the plug to the AC receptacle, making sure that the

power cord is secure.

•

For DC power, you must provide your own cables to connect to the power

source. Cables must be sized for 11.5 A service at no more than -48 VDC

input.

Step

Task

Make sure that the remote power source (the circuit breaker panel) is in

the OFF position.

Remove the safety cover from the DC terminal block.
