Installation and Commissioning Instructions
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. Install according to all relevant safety regulations applicable
to the application.
Mounting
1) Mount chassis securely using mounting holes.
Mains Power Up
2) Attach correctly rated mains cable (minimum 0.5mm2 [3A], 300/500Vac) between external
approved disconnect device and mains input terminal block. Ensure disconnect device has
earth fault protection.
3) Fasten mains cable to chassis using cable ties.
4) Apply mains power. Check for 13.8vdc on load outputs. Check green Mains LED is on.
5) Disconnect mains power.
Load Output
6) Attach correctly rated load cable and fasten in place using cable ties. Note polarity.
7) Apply mains power. Check green Mains LED is on.
8) Disconnect mains power.
Standby Battery
9) Attach supplied battery cables to battery.
NOTE: ensure correct polarity of battery connections: +ve use red lead, -ve use black lead.
10) Check that the batteries supply voltage and current to the load.
NOTE: batteries must have sufficient charge to supply the load
11) Apply mains power. Check green Mains LED is on.
12) Using a meter set to its current measurement range, check for charging current flow into
battery.
Operating Instructions
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.

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. The fuses may need to be
replaced. Ensure the correct fuse rating and type is used.
