The LNL-400XA Power Supply Unit (PSU)
The LNL-400XAis a high-efficiency and cost-effective power supply
designed to house a variety of Lenel controllers and modules in an
OnGuard®system.
Featuring a regulated 13.8 VDC output, the LNL-400XAsupplies
continuous full rated current to load. Maximum battery life is assured using
deep discharge protection to prevent premature battery failure when
operating in standby mode for extended periods. Two sets of volt-free
contacts are provided to signal (i) loss of mains and (ii) battery and loss of
output faults.
The LNL-400XAcan supply a continuous full-rated current to load plus an
additional 0.5A for charging a 12V standby battery.
The universal mains input voltage enables the power supply to be used
across a wide geographical area. The highly efficient switch mode design
ensures low operating costs while generating less heat. The modular
construction simplifies maintenance.
• Continuous full-rated current-to-load
• Universal mains input voltage 90-264 VAC
• High-efficiency electronics for reduced running costs and lower
operating temperatures
• Mains transient protection circuit
• Lid and removal from wall tamper detection
• Installer-safe design with all high-voltage electronics fully shrouded
• PCB supports and fixings supplied
• Houses a variety of Lenel controllers and modules
• PSU status and diagnostic LEDs (mains present and fault)
• Volt-free contact signaling mains failure (EPS)
• Volt-free contact signaling output and battery faults (GEN)
• Full electronic short circuit and overload protection on load output
under mains operation
• Individual battery and output fuse protection
• Three-year warranty
Installation
This unit is only suitable for installation as permanently connected
equipment. The PSU is NOT SUITABLE for external installation.
Before installation, ensure that the mains power source has a separate
(approved) disconnect device that is fitted with a fuse or other over-current
protection rated at 3A maximum. Ensure that the disconnect device has the
appropriate earth fault protection to the applicable standard.
Before connecting the PSU to the mains power source, verify that the
external disconnect device is OFF.
Install the PSU according to all relevant safety regulations applicable to the
application. EQUIPMENT MUST BE EARTHED.
Mounting
1. Mount the PSU securely in correct orientation allowing minimum
clearance. Fasten cables using cable tie securing points as shown.
Mounting the Power Supply
2. Route mains and low voltage output cables via different knockouts
and/or cable entry holes.
Note: Use bushes and cable glands rated to UL94 HB minimum.
Mains Power-up
1. Attach the appropriately-rated mains cable (minimum 0.5mm2[3A],
300/500 VAC) and fasten using cable ties.
2. Apply mains power. Check for 13.8 VDC on load outputs. Ensure that
the green Mains LED is on.
3. Disconnect mains power.
Load Output
1. Attach the appropriately-rated load cable and fasten using cable ties.
Note polarity.
2. Apply mains power. Check green Mains LED is on.
Note: The red LED on the PSU may be on to indicate that no battery
has been connected. This is normal.
3. Verify load is operating correctly.
4. Disconnect mains power.
Standby Battery
1. Attach supplied battery cables to terminal block and battery.
Note: Ensure correct polarity of battery connections: +ve use red lead,
-ve use black lead.
2. Apply mains power. Ensure that the green Mains LED is on.
3. Ensure that there is no fault indication on the red LED (see Signaling
Outputs).
4. 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 load.
5. Reconnect mains power. The green LED should be on.

Tamper
1. Connect tamper switch to appropriate inputs of control and indicating
equipment (CIE).
2. Check that the tamper switch is CLOSED when the lid/cover is closed
and the retaining screw is fitted, OPEN when the retaining screw is
removed and the lid/cover is open. Use fine adjustment screw if
necessary, no more than one turn in either direction, to align indicator
with set point.
3. Close the lid and fasten with screw supplied. Alternatively fit the
cover in place (the correct orientation is with the cover retaining
feature engaging over the bottom lip of the base) and fasten with the
supplied screws.

Operating Instructions
This unit is intended for use by Service Personnel only. There are NO USER
SERVICEABLE parts inside.
The green Mains LED is on while the mains supply is present. In the event
of a fault condition, the red Fault LED flashes and the corresponding (EPS
or GEN) fault signal contacts open.
Maintenance
Note: Dispose of used batteries according to the battery manufacturer’s
instructions and all local and national regulations.
This unit is intended for use by Service Personnel only. There are NO USER
SERVICEABLE parts inside.
There is no regular maintenance required of the PSU other than periodic
testing, calibration check and replacement of the standby batteries.
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.
