1 Receiving and Storage
1.1 Receiving
All possible precautions are taken to protect the equipment against damage or losses during shipment, however before
accepting delivery, check all items against the packing list or Bill of Lading. If there are shortages or evidence of physical
damage, notify Ampcontrol immediately.
Notify Ampcontrol within 7 days (maximum) in case of shortages or discrepancies, according to the packing list. This action will
help ensure a speedy resolution to any perceived problems. Keep a record ofall claims and correspondence. Photographsare
recommended.
Where practicable do not remove protective covers prior to installation unless there are indications ofdamage. Boxesopenedfor
inspection and inventory should be carefully repacked to ensure protection ofthe contents or else the parts should be packaged
and stored in a safe place. Examine all packing boxes, wrappings and covers for items attached to them, especially if the
wrappings are to be discarded.
1.2 Storage after Delivery
When the equipmentis notto be installed immediately, proper storage is importantto ensure protection ofequipmentand validity
of warranty.
All equipment should be stored indoors, preferably on shelves (where practicable), and protected from the elements. Ifstoring
on the ground use wooden blocks to elevate the equipment above the ground and ensure thatthe storage area is notan area
where water will collect. The storage location mustnotbe in directsunlightand must stay within the temperature range of -10 to
+60°C.
1.3 Unpacking of Equipment
The method of packing used will depend on the size and quantity ofthe equipment. The following cautions should be interpreted
as appropriate.
CAUTION!
Take care when unpacking crates as the contents may have shifted during transport.
Make sure that cable drums are securely attached to their shipping pallets before attempting
to move them.
The disposal of packaging materials, replaced parts, or components must comply with
environmental restrictions without polluting the soil, air or water.
Ensure that any timber and cardboard used as packaging is disposed of in a safe and
environmentally responsible manner.
Where possible, dispose ofall waste products i.e. oils, metals, plastic and rubber products by using
an approved recycling service centre.

2 General safety
2.1 Personnel Safety Warnings
2.1.1 Relevant Personnel
All personnel directly responsible for the installation, operation and maintenance of the equipmentshould ensure thatthey are
aware of, before start-up, any instructions in safety, as well as attend any scheduled facility safety meetings.
Site meetings should address and record such health and safety issues as:
Risk assessment and a subsequent work method statement.
Evacuation and rescue plans.
Identification of Safety Officers.
Identification of medical facilities.
Any special site requirements
Each person who is concerned with the installation, start-up, operation, maintenance, repair work, or with any possible
disassembly or reassembly of the equipment, must observe any instructions issued at site meetings.
2.1.2 Safety Communication
All safety instructions should be passed on to other users. As well as the instructions given in this manual, the Safety Instructions
and Rules for the Prevention ofAccidents generally applicable to this type ofwork have to be followed, as well as any Site Safety
Rules or Regulations. The responsibilities applicable to those persons who work with the equipmentmustbe clearly laid down.
2.2 Safe Use of Equipment
The equipmentsupplied has been manufactured according to the state ofthe art, and designed to ensure a safe operation. The
equipment may only be used within the design parameters.
In general, the following instructions must be observed in order to help achieve maximum safety during operation.
The owner/user is responsible for observing the following instructions:
2.2.1 Live Conductors
No work shall be carried outon live conductors (exceptintrinsically safe) energized by any voltage where equipmentis operating
in, or connected by cabling to, any hazardous zone. This does notpreclude the use of IS test instruments provided their use is
as detailed in HB13-2007 Section 11 (Standards Australia Handbook-Electrical equipment for hazardous areas).
2.2.2 Equipment Knowledge
Experience with, or understanding of, this equipment is essential for the safe installation and removal of the equipment.
Therefore, in case of a question on how to safely proceed, contact Ampcontrol immediately.
Mechanical and or Electrical installation, and maintenance of plant and equipment, must only be carried out by appropriately
qualified personnel.

3 Overview of Equipment
3.1 Description
The Ampcontrol CPS-A Intrinsically Safe Compact Power supply forms part of the Gasguard Range of Group I certified Gas
Detection and Alarm Systems and is also suitable for use with other applications.
The CPS series of IS power supplies convert 110Vac mains power to intrinsically safe low voltage DC power.
The DIN rail mount enclosure is made ofrobustblack polycarbonate. Top and bottom enclosure walls have ventilation slots for
natural convection cooling. The side walls are solid and allow other components to be mounted adjacentto iton the DIN rail.Top
and bottom ventilation slots must be kept free for air circulation. Screw terminals are located on the frontfor connecting the AC
mains cable and the output load circuits. The output has two terminals for each of the positive and negative DC supply.
WARNING!
The power supply must be mounted in a safe area or in a suitable enclosure with a minimum
IP 54 rating.
Typical use of this power supply is for voice communication systems, gas detection systems and other electronic equipment
requiring intrinsically safe power in a Group I application.
The CPS-A Power supply is an IP 20 plastic enclosure DIN rail mounting Intrinsically Safe power supply designed for Group I
applications. Several power output versions of the Power Supply are available with a range of voltage and current limits.
Mounting is by a moulded clip assembly onto a standard TS32 top hat DIN rail.
Connections are made to enclosed screw clamp type terminals on the front facia of the enclosure.

4 Installation
Install the CPS-A power supply on a TS 32 type DIN rail in a cool, dry, dust and vibration free area.
CAUTION!
The unit should be installed with the ventilation slots on the top and lower faces to ensure
proper ventilation.
Take care not to allow swarf and other metallic items to penetrate the enclosure during
installation of adjacent equipment.
Ensure adequate space above and below the unit to allow free air movement through the
slots.
WARNING!
The input mains terminals and output DC terminals have minimum separation distance of
50mm. This separation must be maintained by using insulated wires & lugs.
Wiring to the CPS-A must comply with local wiring codes and Intrinsically Safe standards
as applicable to the application.

5 Operation
WARNING!
The CPS-A has no user serviceable parts. All repairs must be carried out by Ampcontrol
personnel only. If a fault develops return the CPS-A to Ampcontrol for repair. It is
essential that no attempt be made to repair the CPS-A as any attempt to dismantle or
repair the CPS-A can seriously compromise the safety of the unit and the consequence
can be fatal.
The power supply is of an active type and exhibits very low outputimpedance. The outputvoltage is reduced by only 0.3V atfull
load. Precise active currentlimiting provides maximum available currentup to the Io parameter. The power supply outputacts
as a current limited voltage source. The load impedance can vary down to short circuit while the maximum output current is
maintained. The red overload LED on the facia lights up when operating in current limit.
The OUTPUT LED is driven directly by the output voltage. If the Power Supply is in current limit mode the OUTPUT LED
reduces in intensity with the lower outputvoltage. The OUTPUT SWITCH LED confirms thatthe internal control circuit is healthy
and the output is active. The OUTPUT SWITCH LED turns off when mains power is removed or if a fault occurs.
CAUTION!
If mains power is healthy but the OUTPUT SWITCH indicator is OFF, this indicates a fault
has developed. Return the power supply to Ampcontrol for repair.
Note ventilation slots (Top and bottom)
