Product Usage Instructions

Operating Instructions

This unit is intended for use by trained Service Personnel only. Once installed and operational, there are no user functions other than observance of the two LED indicators. The green Mains LED will be illuminated while the mains supply is present. In the event of a fault condition, the lower Fault LED will be illuminated as specified on page 7 of the user manual.

Installation and Commissioning

Installation and repair must be carried out by a certified professional or qualified electrician in accordance with all relevant safety regulations. This unit is only suitable for installation as permanently connected equipment and is not suitable for external installation. It must be fed from a mains power source with a separate (approved) disconnect device and fitted with a fuse or other over-current protection device rated at a maximum of 3A. Ensure that the disconnect device used has appropriate earth fault protection to the applicable standard and before installation, ensure that the external disconnect device is OFF.

EQUIPMENT MUST BE EARTHED.

• Medium enclosure: 3 fixing positions
• Large enclosure: 5 fixing positions

Connections

• +LOAD: Red +ve voltage output to load equipment
• -LOAD: Black -ve voltage output to load equipment
• +BATT: Red lead to standby battery
• -BATT: Black lead to standby battery
• Tamper x 2: Tamper volt free contact
• EPS: Volt free contacts for loss of mains indication

FEATURES

• Continuous full-rated current to load.
• Universal mains input rated voltage ranging from 100Vac to 240Vac.
• 12Vdc, 24Vdc and selectable 12Vdc / 24Vdc options.
• High-efficiency electronics for reduced running costs and lower operating temperatures.
• Installer safe design with all high voltage electronics fully protected.
• Full electronic short circuit and overload protection on load output under mains operation.
• Mains transient protection circuit.
• Front and rear tamper detection.
• Mains present LED.
• LED Fault indication.
• Universal mounting means for 3rd party Control Modules.
• Individually fused output(s).
• Deep discharge protection helps prevent battery failure when operating in standby mode for extended periods.

SAFETY

Refer to the Power Supply Equipment (PSE) instruction for safe use.

OPERATING INSTRUCTIONS

This unit is intended for use by trained Service Personnel only. Once installed and operational there are no user functions other than observance of the two LED indicators. The green Mains LED will be illuminated whilst the mains supply is present. In the event of a fault condition, the lower Fault LED will be illuminated under the conditions shown

INSTALLATION AND COMMISSIONING

Installation and repair must be carried out by a certified professional or qualified electrician in accordance with all relevant safety regulations that are applicable. This unit is only suitable for installation as permanently connected equipment. This PSU is NOT SUITABLE for external installation. This unit must be fed from a mains power source having a separate (approved) disconnect device and fitted with a fuse or other over-current protection device rated at 3A maximum. Ensure that the disconnect device used has appropriate earth fault protection to the applicable standard and before installation, ensure that external disconnect device is OFF.

EQUIPMENT MUST BE EARTHED.

• Mounting
  • Mount enclosure securely in the orientation shown on Page 2 using 5mm diameter x 25mm minimum long screws that are appropriate for the mounting material.
  • Allow minimum clearance of 100mm between the enclosure sides and ceilings or adjacent walls. The enclosure must be mounted on a solid and continuous surface (e.g.: a wall, not a column).
• Cabling
  • Route mains and low voltage/signal cables via separate cable entry holes.
  • Use bushes and cable glands rated to the required standard.
• Mains Power Up
  • Attach correctly rated mains cable (minimum 0.5mm2 [3A], 300/500Vac) and fasten using cable ties.
  • In the case of the 12/24Vdc switchable Power Supply, check that the correct output voltage is selected.
  • Apply mains power. Check for the correct output voltage on load outputs.
  • Check green Main LED is on.
  • Disconnect mains power.
• Load Output

outputs)

• Attach correctly rated load cable and fasten using cable ties. Check polarity
• Apply mains power and check green mains LED is on.

NOTE: Fault LED may be lit to indicate that no battery has been connected. This is normal.

• Verify load is operating correctly.
• Disconnect mains power.

Standby battery

NOTE: Ensure batteries being fitted to the unit are in good condition.

• Attach supplied battery cables to the terminal block and then the battery.
  NOTE : Ensure correct polarity of connections: +ve = red lead, -ve = black lead.

• For 24V systems with two batteries, connect as diagram below.

• Apply mains power and check green Mains LED is on.

• Check the fault indication LED is not illuminated.

• Disconnect mains power. Check that the batteries continue to supply voltage and current to the load. The Green LED should be off.
  NOTE: Batteries must have sufficient charge to supply the attached load.

• Reconnect mains power. Green LED should be on.

• Disconnect mains power, remove load fuse and check Fault LED is on.

• Replace Load fuse. Reconnect mains power, check Fault LED is off.

Tamper

• Connect tamper switch to the inputs of the control and indicating equipment (CIE).
• Close the lid and secure with the screw provided.
• With the unit mounted on the wall, check that the rear tamper is not over a recess or raised area that will adversely affect its operation (e.g., over a mortar course).
• Check that the tamper switch is:
  • CLOSED when the cover is closed and the lid retaining screws are fitted.
  • OPEN when the retaining screws are removed.
• Use the adjustment screw if necessary to ensure the tamper switch operates when the lid opens and closes.
• Close and fasten the cover. Re-check the tamper circuit is closed at the control panel.

3RD PARTY CONTROLLERS

The hole pattern in the enclosures allows a wide variety of 3rd-party controllers to be mounted in any position. A fixing kit is included that comprises different sizes of standoffs and self-tapping screws for this purpose.
For PCB type controllers, use arrowhead type standoffs:

For controllers that are mounted using screws:

1. Align controller in suitable position in enclosure.
2. Fasten screws (Max torque 0.6Nm.) Screw types supplied:
   • No 8 x 3/8” long
   • M4 x 25mm long Taptite

MAINTENANCE

There is no regular maintenance required of the PSU other than periodic testing and replacement of the standby battery. Reference should be made to the battery manufacturer’s documentation to determine typical/expected battery life with a view to periodic replacement of the battery. If the output of the PSU fails, the cause of the failure should be investigated e.g., short circuit load. The fault should be rectified before restoring power to the PSU. If a fuse needs to be replaced, ensure the correct rating and type is used.
