I NSTALLATION I NSTRUCTIONS
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. 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 .
Mounting
1) ount securely in correct orientation allowing minimum clearance – see
Fig. 1.0
2) Route mains and low voltage output cables via different knockouts
and/or cable entry holes.
3) Use bushes and cable glands rated to UL94 HB minimum.
Mains Power Up
4) Attach correctly rated mains cable (minimum 0.5mm
2
[3A], 300/500Vac). Fasten with cable ties.
5) Apply mains power.
Check for 13.8Vdc on load outputs.
Check Green ains LED is ON.
6) Disconnect mains power.
Load Output
7) Attach correctly rated load cable and fasten using cable ties. Note polarity.
8) Apply mains power.
Check Green ains LED is ON.
NOTE: Red Fault LED may flash to indicate no battery has been connected, this is normal.
Verify load is operating correctly.
9) Disconnect mains power.
Signalling
10) Connect EPS and GEN fault outputs to appropriate inputs of Control and Indicating Equipment (CIE).
Standby Battery
11) Attach battery cables to terminal block and batteries.
NOTE: ensure correct polarity of battery connections: +ve use Red lead, -ve use Black lead.

O PERATING I NSTRUCTIONS
In the event of loss of mains, a battery fault or a GEN fault, the corresponding Fault signal contacts will open (see Fault
diagnostic table for LED indicator status).
If the output of the PSU fails, the cause of the failure should be investigated e.g. short circuit load, connection of a
deeply discharged battery. The fault should be rectified before restoring power to the PSU. If any of the fuses require
replacing, ensure the correct fuse rating and type is used.
M AINTENANCE
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, and replacement of the standby
battery. Reference should be made to the battery manufacturer's documentation to determine typical/expected
battery life with a iew to periodic replacement of the battery.
