1 Description
The SurgeX® XQ515 is a 120V 20 amp three-bank AC power sequencer incorporating SurgeX
Advanced Series Mode® power conditioning and surge protection. The surge protection is rated
A-1-1, the highest standard of the Federal Commercial Item Description for Endurance. The two
rack-space steel enclosure is designed to be installed in a 19 inch equipment rack. A total of
fourteen 120V receptacles are provided on the rear panel, two of which are always on, with the
remaining twelve configured as three sequenced banks of four receptacles, labeled A, B and C.
Bank C (which is next to the two always-on receptacles on the rear panel) can itself be
configured to be always on, increasing the number of always-on receptacles to six.
SurgeX ICE® Inrush Current Elimination circuitry is incorporated into the XQ515. This
eliminates problems associated with inrush currents from large loads such as amplifiers. With
SurgeX ICE® it is not necessary to take inrush currents into account when designing the AC
power for a system, and special time-delay circuit breakers are not required: you only need to
ensure that the steady-state currents of all products plugged into the XQ515 are within the 15
Amp rating.
The front panel houses a two-line back-lit LCD display which provides status information in
normal use and allows interaction with menu items during programming. Also on the front panel
are two screwdriver-accessible rotary encoders which are used to step through and select from a
menu of items which determine the operation of the unit. The red push button, when pressed,
causes the unit to power up or power down. This button can be disabled if not required. The red
LED above the button indicates the status of the unit. When the red LED is off the unit is fully
powered down; when it is on the unit is fully powered up; when it is flashing the unit is in the
process of powering up or down.
A built-in AC voltmeter indicates the line voltage on the LCD display. The internal voltmeter is
a peak reading type which was chosen because most electronic equipment incorporates a power
supply that charges mostly during the AC peaks. Monitoring the peak of the AC provides a more
useful indication of the real voltage available to the electronic equipment plugged into the
XQ515.
The XQ515 is microprocessor controlled and designed to be versatile and expandable. Two or
more XQ515s can be connected together to provide control and power conditioning for larger
systems. The XQ515 can also control other SurgeX products like the XR315 with its auxiliary
relay contacts and/or its 12V DC output. All options are set via the front panel and all
connections are made at the rear panel. An optional password of up to six letters can be entered
preventing unauthorized access to set-up information. All set-up information is stored in nonvolatile memory.
A plug-in Phoenix terminal block on the rear panel accommodates the remote control
connections and also the low-voltage outputs. There are three inputs which control sequencing;
one programmable 12V dc output; and one programmable auxiliary relay providing normallyopen contacts. The inputs can be controlled by an applied DC voltage from 5V to 30V, by a
contact closure, or by different types of switch; the input selection being made during
®

programming. The inputs and 12V output are designed to withstand incorrect connections
including polarity reversal and shorts.

3 Installation
The SurgeX XQ515 is designed to be installed in a 19 inch equipment rack and requires two
units (2-U) of rack space. Use the four screws provided with the product to secure the rack ears
to the rack rails. These screws can be tightened by hand and do not require tools. Connect power
to the unit by plugging the cord into a 120V ac, 15 Amp receptacle.
3.1 120 Volt Connections
The XQ515 has a total of 14 receptacles: three sequenced banks of four, and two always on.
Each receptacle is rated for a maximum load of 15 amps but the total load of the XQ515 must
not exceed 15 Amps. Plug the equipment cords into the receptacle banks as needed to turn on
equipment in the required sequence. The “always on” receptacles provide power as long as
power is supplied to the XQ515. Bank “A” always powers up first and off last.

3.2 Remote Control Connections
Pin 1 – Up Input
Pin 2 – Down Input
Pin 3 – Over-Ride Input
Pin 4 – 12 V dc Output
Pin 5 – Common
Pin 6 – Aux Relay Contact
Pin 7 – Aux Relay Contact
Remote connections are wired to the green 7-pin plug-in Phoenix terminal block on the rear of
the unit next to the power cord. The terminal block itself is provided in the accessory bag that
you will find in the shipping box. After you have made the connections to the terminal block,
plug it into the connector on the rear of the unit. Never solder (tin) wires before inserting in a
terminal block – solder creeps and you will eventually have loose connections!
The connections are shown below:
3.2.1 Up/Down XQ515uence Control Inputs
The XQ515 can be controlled by a DC voltage in the range 5V to 30V, by a contact closure (such
as a relay), or by a switch. In this manual the terms “momentary” and “latching” are used when
describing switches. A momentary switch is considered to be a switch which provides a
connection only while it is actually held pressed, and a latching switch is considered to be a
switch which remains in either the on or the off state (like a light switch). Momentary switches
are preferred for use with the XQ515 since multiple control locations can be used, and also
because some of the functions of the XQ515 are not available when a latching switch is used (see
programming section). Switches with gold contacts are recommended for the best long-term
reliability. The type of input is selected totally through programming, making the electrical
connections straightforward. The six control options are discussed below:
a) DC Voltage: The XQ515 will power up when the voltage is present and power down
when there is no voltage. Connect the positive wire to the “up” input, and the ground (or
negative) wire to “common”. Program the input for “5-30 V dc”.
b) Contact Closure: The XQ515 will power up when the contacts are closed and power
down when the contacts are open. Connect the two wires from the contacts to “up” and
“common”. Program the input for “Latching”
c) Momentary Switch(es): The XQ515 will power up when a switch is pressed once and
power down when a switch is pressed a second time. Connect the two wires from the
switch(es) to “up” and “common”. Program the input for “Momentary”.
d) Separate Up & Down Switches: The XQ515 will power up when the UP switch is
pressed and power down when the DOWN switch is pressed. Connect the two wires from
7
the UP switch to “up” and “common”, and the two wires from the DOWN switch to
“down” and “common”. Program the input for “Separate Up & Down”.
e) Center-Off Switch: The XQ515 will power up when the switch is pressed to the UP
position and power down when the switch is pressed to the DOWN position. Connect the
wire from the UP terminal to “up”, the wire from the DOWN terminal to “down”, and the
wire from the COMMON terminal to “common”. Program the input for “Separate Up &
Down”.
f) Latching Switch: The XQ515 will power up when the switch is closed and power down
when the switch is open. Connect the two wires from the switch to “up” and “common”.
Program the input for “Latching”.
Note: The front panel button will not operate with options a, b or f
3.2.2 Over-Ride Input
The XQ515 has the option of adding an over-ride function for purposes such as providing fire
safety over-ride to force the system either on or off. An over-ride is initiated by applying a dc
voltage of 5-30V or by a sustained contact closure. The selection of dc voltage or contact closure
is accomplished during programming. This topic is covered fully in the programming section.
Connect the over-ride signal to the “over-ride” input and “common”. In the case of a dc voltage,
connect the positive wire to “over-ride” and the negative wire to “common”.
3.2.3 External LED Connections
The XQ515 is able to drive external LEDs or other signaling devices through its 12V dc output
which can provide up to 40mA of current. External LEDs connected in this way will mimic the
red LED on the front panel. When connecting LEDs to the 12V output, a series resistor is
required. For example, many LEDs work well with 10mA of current, so a 1K resistor is usually a
good choice. If more than one LED is required, then use a separate series resistor for each LED.
In this example, four external LEDs could be powered at 10mA each from one XQ515. If more
than four LEDs are required, it will be necessary to increase the series resistor so that the total
load is not more than 40mA.
Connect each LED anode to “12V dc output” through a resistor, and the cathodes to “common”.
Program the 12V dc Output for “LED”. This causes LEDs connected to the XQ515 to flash
while the unit is powering up or powering down in the same manner as the front panel LED.
3.2.4 Confirmation Connection
The XQ515 offers two ways to provide confirmation feedback to a central controller: a 12V dc
output and isolated relay contacts. Confirmation tells the controller that the XQ515 has indeed
powered up or that it is fully powered down. If the 12V dc output and the aux relay contacts are
not used for any other function, you will be free to choose whichever provides the best interface
8
for the application. However, if one of these outputs is used for another function you will have to
12V dc Output
Common
use the one that is available.
To use the 12V dc output for confirmation, connect “12V dc output” to the positive input of the
controller and “common” to ground. The output will be at 12V when all banks are powered up
and will be zero when all banks are powered down. Program 12V dc Output for “Confirm”. Note
that the XQ515 common terminal is shared between the inputs and the 12V dc output. If you
need relay contacts for confirmation and you are using the aux relay for another function you can
connect a small relay between the 12V dc output and common. The relay coil current must not be
more than 40mA, and you must connect a diode such as a 1N4148 or 1N4002 across the relay
coil (cathode to +12V dc) to suppress the back-EMF from the coil. If you need assistance with
this please contact our technical support department.
Connecting a 12 volt relay to the 12V dc output
To use the auxiliary relay contacts for confirmation, connect the contacts to the input of the
controller. The relay contacts will be closed when all banks are powered up and open when all
banks are powered down. The default for menu item “Aux Output” is “Confirm” so you do not
need to program this item unless you previously changed it. The contacts are rated for 30V dc at
1 amp.
4 Quick Start
This section is intended to allow users with a simple straightforward system incorporating a
single XQ515 to get up and running with the minimum of effort. If this is not the case then skip
this section and go directly to the section on detailed programming (section 5). If you are going
to follow the quick start instructions, you only need to perform the following steps since the unit
has been shipped with default settings suitable for basic operation.
1. Make all connections as per section 3.

2. Insert the screwdriver provided in the accessory kit in the hole labeled SEL and turn it one
click clockwise. Press the red button and you will see the first menu item “Bank C Function”
on the display. Leave this set to sequence unless you want to use Bank C as Always On
receptacles. In that case insert the screwdriver in the hole labeled ADJ and turn one click
clockwise to change it to Always On.
3. Advance SEL one click to get the second menu item “Up & Down Inputs”. Select the option
required for the install by referring to section 3.2.1 and set the option by rotating ADJ.
4. Advance SEL one more click. You will now be able to set the first delay time which is for
bank A powering up. Use ADJ to set the required delay time in seconds.
5. Advancing SEL one click at a time and using ADJ to adjust the delay times, set the
remaining five delay times: B on, C on, A off, B off, C off. If you have set Bank C to be
Always On skip the delay settings for Bank C.
6. If you have connected an LED to the 12V dc output for remote signaling, step through the
menu until you reach “12V dc Output”. Then advance ADJ to select “LED”. This selection
will make the remote LED mimic the LED on the front panel which flashes while the unit is
powering up or powering down.
7. Turn SEL fully counter-clockwise and press the red button to exit programming. Place two of
the black plugs from the accessory kit into the adjustment holes to deter tampering and the
unit is ready for use.
Although the above steps are all that are required to get the XQ515 running, you may want to
take a look at the following programming options to see if you want to make use of any of these
functions. You will find these listed on the reverse side of the Programming and Connection
Guide, and they are near the end of the menu that you step through by turning SEL.
Low Voltage Shutdown Shuts unit off if AC voltage drops below the set point
High Voltage Shutdown Shuts unit off if AC voltage rises above the set point
Self-Test Shutdown Shuts down unit if self-test fails
Power Fail Restore Turns unit back on after a power failure if unit
was powered up when the power failed
