Medium enclosure: 3 fixing positions

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 on page 7.

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.

1. 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).

2. Cabling

•Route mains and low voltage/signal cables via separate cable entry holes.

•Use bushes and cable glands rated to the required standard.

3. 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.

•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.

5. Standby battery

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

•Attach supplied battery cables to 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.

6. 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:

2. Align controller in

suitable position in

enclosure.

1. Fit standoffs into

suitable PCB mounting

holes. Ensure correctly

sized standoffs (3mm

or 4mm) are selected.

3. Press standoffs into

selected hole position.

1. Align controller in

suitable position in

enclosure.

2. Fasten screws (Max torque 0.6Nm.)

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.
