fault. Since any wiring fault presents a potentially serious safety hazard, the assistance of a qualified electrician should be obtained in correcting the problem.
NOTE: The Mains Wiring indicators and status LEDs stay on even when the power switch is off. This feature allows you to check the mains wiring before powering up your equipment. These indicators are designed for continuous, ongoing use. Like a clock, they consume very little power.
UNSWITCHED OUTLET: This convenient outlet pro- vides power at all times when the PS-PRO is plugged in and operating under normal power conditions.
ON/REM/OFF SWITCH: When turned to the ON posi- tion, this key lock switch initiates an ON sequence, applying power to the PS-PRO’s switched outlets. When turned to the OFF position, it begins an OFF sequence. In the REM position, the PS-PRO will accept on/off commands from a remote switch or switches that may be connected to the rear panel terminals.

3.After the front panel switch is thrown to ON, Delay 1 outlets receive power instantly, Delay 2 outlets receive power 1-30 seconds later and Delay 3 outlets receive power 130 seconds after Delay 2 outlets are powered. When thrown to OFF, the sequence is reversed, with
Delay 3 losing power instantly, Delay 2 outlets los- ing power 1-30 seconds later and Delay 1 outlets losing power 1-30 seconds after Delay 2 outlets are shut down. The delay intervals may be altered with the screwdriver-adjustable Delay Adjust control on the front panel.
TERMINAL STRIP: Allows one or more switches to be connected to turn the PS-PRO on and off from a re- mote location. Two, and sometimes three, wires are
CIRCUIT BREAKER: The overall capacity of the PS-PRO is 20 amps. If the combined steady-state current drawn by all devices plugged into all of its nine outlets level exceeds 20 amps at any time, the circuit breaker will trip, cutting off power to your rack. If this occurs, you must reduce the load by unplugging one or more units from the PS-PRO, and reset it. You can reset the circuit breaker by simply pressing in the button, which pops out when tripped. However, because it is a thermal type, you may have to wait a few moments after it trips for it to cool down before it will allow you to reset it.
UNSWITCHED OUTLETS: The PS-PRO rear panel pro- vides clean, filtered power to this pair of unswitched outlets, adjacent to the power cord.
SWITCHED (DELAYED) OUTLETS: The PS-PRO rear panel provides three pairs of switched outlets, widely spaced to allow use of equipment with plug- in (wall wart) transformers. These switched outlet pairs are labeled Delay 1, Delay 2 and Delay
needed to install a remote switch (see “Maintained Mode”, page 6.) If a four-conductor cable is used, an LED may be installed at the remote end to indicate
that the power is on.
