O PERATIO
This unit is intended for use by Service Personnel only - There are NO USER SERVICEABLE parts inside.
The Green Mains LED will be illuminated whilst the mains supply is present. In the event of a fault condition,
the Yellow Fault LED will be illuminated.
I STALLATIO A D S ET -U P
This unit is only suitable for installation as permanently connected equipment. The PSU is NOT SUITABLE for
external installation. EQUIPMENT MUST BE EARTHED. Before installation, ensure that external disconnect
device is OFF. The PSU should be installed according to all relevant safety regulations applicable to the
application.
Enclosure and Mounting
This power supply module has high voltage present and is for use by Service Personnel only. This power
supply module MUST be securely mounted within a robust enclosure having suitable means to prevent
unintentional access to the module. Suitable notices must be affixed to the outside of the enclosure to warn
of high voltages present internally.
Mounting the module
1) Mount securely in correct orientation allowing minimum clearance of 20mm all round – see diagrams
below.
2) The G2401NU and G2402NU modules have the option of either being DIN rail mounted (using the
integrated DIN rail mount) or by using appropriate fixings using the four available mounting lugs. The
G2403NU and G2405NU modules are fixed using the three available mounting points.
Mains Power Up
3) Attach correctly rated mains cable (minimum 0.5mm
2
[3A], 300/500Vac) and secure in enclosure using
cable ties.
4) Apply mains power. Check for 27.6Vdc on load outputs. Check Green Mains LED is on.
5) Disconnect mains power.
Load Output
6) Attach correctly rated load cable and secure in enclosure using cable ties. Note polarity.
7) Apply mains power. Check green Mains LED is on.
8) Verify load is operating correctly.
9) Disconnect mains power.

Standby Battery - OTE: Ensure batteries fitted to this unit are in good condition
10) Connect battery to terminal block using minimum 32/0.2 (1.0mm
2
CSA) stranded wire.
OTE: ensure correct polarity of battery connections.
Maximum recommended total battery lead length = 500mm
11) Apply mains power. Check Green Mains LED is on.
12) Check there is no fault indication on Yellow LED.
13) Disconnect mains power. Check that the batteries continue to supply voltage and current to the load.
The Green LED should be off.
OTE: Batteries must have sufficient charge to supply the load
14) Reconnect mains power. Green LED should be on.
15) Remove Load fuse and check Yellow Fault LED is on.
16) Replace Load fuse. Check Yellow Fault LED is off.

M AI TE A CE
There is no regular maintenance required of the PSU other than periodic testing 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.
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. The fuses may need to be replaced. Ensure the
correct fuse rating and type is used.
