Power Supplies
This manual describes the installation, care and use of the Continuum power supply
modules.
The Continuum power supply modules are part of the Andover Controls
Continuum
Ethernet-based intelligent building system. The
Continuum system allows you to cost-
effectively mix and match DIN rail-mounted CPU, power supply, and various
combinations of I/O modules and user interfaces to meet your control and monitoring
needs. The power supplies offered include an impressive array of features.
Along with the standard 120/240 VAC modules, some models reduce or eliminate the
impact of power failure through a built-in battery back-up system with integral charger.
Another allows – 48VDC power based industries such as telecommunications to provide
uninterrupted power to critical environmental monitoring and control equipment using
their own battery-backed power systems.
Each module includes provision for an optional AC power indicator LED. This option is
ideal if you mount your
Continuum system within a larger control panel or enclosure and
wish to verify power to the system from a separate location.
The power supply modules feature a sleek, lightweight casing designed for natural
convection cooling. Quick-release fasteners, built-into the back of the module, are
provided for DIN rail mountingno tools required. These fasteners also snap into a
locked position that features integral reinforced holes for panel mounting in non-DIN
situations.

Mechanical Installation
Note to the installer:
This device must be properly installed to suit it's intended application.
European Installations:
These power supplies are listed as Class 1 devices intended for installation in
an IP2 enclosure. The Continuum Enclosure is an IP2 enclosure.
ATTENTION: Disconnect from supply before removing!
The power supply modules can be mounted to a standard DIN rail or be directly
mounted to a panel using screws. Hardware facilitating both mounting methods is
included as an integral part of the case design.
On the back of each module are molded DIN rail guide fingers. The design allows the
module to easily hook onto and slide along a standard DIN rail.
Special clamps are provided on the case that allow you to lock the module in place,
once it is in position.

Continuum Power Supply Reference 5
Once the module is in the desired position, it is locked to the rail by pushing the
bottom clamps inward. After the bottom is secure, press the top clamp inward to
complete the operation.
These clamps, when extended, provide an alternative method of mounting to the DIN
rail. You can mount the module directly to a panel using the reinforced mounting
holes provided on each of the clamps.

The AC connection consists of both terminals (Hot and Neutral) from the power-line
and a third wire tied to a common Earth ground.
• High voltage AC Power wiring should be routed to the conduit opening nearest
the AC power terminals.
• Do not bundle or route AC Power wiring with low voltage input or output wiring.
• Be absolutely certain that your USA installation complies with all aspects of the
National Electric Code, NFPA 70. Be
especially
sure that your system is properly
grounded.
Warning
Make sure that AC power is
not
applied to the power cable while you are
wiring the module, or you could receive an electrical shock that is life-
threatening.
Connecting Grounds
The power supply must be connected to true Earth ground. When used in an
enclosure, be sure to connect the enclosure to Earth ground as well. The Continuum
enclosure includes a special Chassis Ground stud that can be found at the lower left
bottom of the inside as shown below. Connect your grounds at that point.
Connect incoming power line Ground
And Power Supply Ground to this point.

Continuum Power Supply Reference 9
Building Ground Requirements
Be sure that all equipment from Andover Controls is grounded to true Earth ground.
True Earth ground protects the equipment from transients and other power surges in
the area. We cannot guarantee that the controller system will operate as documented
without a properly grounded installation.
An example of a sub-standard ground is a galvanized steel cold water pipe. As the
pipe corrodes, it does not act as a true ground. The corrosion acts as an insulator,
raising the potential of the pipe with respect to the ground.
When lightning strikes in the area of the installation, it drastically changes the
potential of the Earth. Since properly grounded Andover Controls units respond to
changes in potential more rapidly than poorly grounded electrical systems, a poorly
grounded building tries to reach ground through the Andover Controls system. The
surge of current can destroy electronic components on the controller board. Surges
of much lower potential than lightning also impact the reliability of the equipment.
Inspecting the Ground
Be sure to have your grounds inspected before you begin the installation process to
be sure your municipality follows the National Electrical Code.
Many municipalities
do not follow the code and often have substandard electrical grounds.
Check your ground as follows:
Inspect the building power distribution panel for Earth-ground termination. If the
ground termination is any of the following, it is not adequate and must be corrected:
• Does not exist.
• Is connected to a corroded or galvanized pipe.
• Is connected using a small gauge wire (less than 14 AWG).
Be sure your Andover Controls cabinet is connected to the ground with a copper
conductor that terminates at the distribution panel.
Lightning Protection
Metal oxide varistors are built into the power supply to protect against power line
transients.

UPS Connections
The following information pertains to the AC 50-U and AC 85-U models only.
Backup Battery Connection
The PS 120/240 AC 50-U and AC 85-U power supplies include provisions for
connecting an external lead-acid battery supply to power the system in the event of a
main AC power failure.
An external 24 Volt battery pack may be sized to provide the hold-up time specified
by system requirements. Using standard 12V or 24V batteries, (120 to 160 W•Hr),
the built-in UPS circuitry provides a backup time of 60 minutes @ 35 Watts power
consumption. The integral 15 Watt battery charger has a worst case charging time of
48 hours with two (2) 12V, 7.0 Ahr batteries.
For UL 1076 applications, two 12 VDC 40Ahr batteries insures a supply that will
power approximately 5 hours of back-up operation. For more information, obtain the
Continuum UL 1076 Burglar Alarm System Guide 30-3001-800.
To protect the batteries, the battery cutoff circuitry will activate at 20.4 volts.
The external battery pack connects to the module through a two-position screw
terminal connector. Replacement of the external battery for maintenance purposes
may be performed while the unit is AC powered without interruption of service.

Output Power Connection
The power output connector is a five pin male assembly that is designed to easily
insert directly into the left side (input) connector of any CPU or I/O module. The
signals within that connector are as follows:
PIN Function
5 +VDC
4 VDC Return
3 No Connection
2 Low Battery *
1 AC Power *
* Only on PS 120/240 AC 50-U and AC 85-U
All the Continuum power supply modules (except the AC 25 model) generate a +24
VDC source for all other modules in the system. The PS 120/240 AC 25 power
supply generates +5 VDC. This power source is located on pins 4 and 5.
The UPS versions of these supplies include two power status signals on pins 1 and
2. Their function is as follows:
AC Power is a logic signal that is intended to communicate to an attached CPU
module that AC power is available. When AC is interrupted and the power supply
has switched to UPS battery mode, this signal presents a logic low to the CPU. The
CPU can use this signal to start an orderly system shutdown. For more information
on the use of this signal refer to the Continuum CPU Reference #30-3001-703.
Low Battery is a logic signal that is intended to communicate to an attached CPU
module that the voltage of the battery has dropped below 22 Volts. When the
power supply is in UPS battery mode, this signal presents a logic high to the CPU.
Should the battery voltage drop, this signal switches to a logic low. The CPU uses
this signal to start an orderly system shutdown. For more information on the use of
this signal refer to the Continuum CPU Reference #30-3001-703.

Output Connections
PS 120/240 AC 50(U), AC 85(U), -48 DC 50
The PS 120/240 AC-50(U), AC 85(U) and –48 DC 50 power supply modules directly
connect to others without the use of cables through a system of built-in plugs and
jacks. All modules except the power supply include two complementary module inter-
connectors.
The power supply becomes the first module feeding the CPU. All other modules are
then connected to the CPU.
Important: When powering a CPU, the power supply connects directly to the
left side of the CPU. Do not place any I/O modules between the power supply
and the CPU.
Creating a system is as simple as physically plugging the modules together into a
stack.
In vertical extended systems, I/O modules may be located above or below other
modules. In this case, cable assemblies bridge the I/O modules together.
