NSTALLATION
This unit is only suitable for installation as permanently connected equipment. The 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 5 A maximum. Ensure that the disconnect device used has
appropriate earth fault protection to the applicable standard.
Where the PSU is used to provide power to a fire alarm circuit, the mains isolation and disconnect device should be
provided solely for this purpose and be suitably marked “FIRE ALARM –
DO NOT TURN OFF”. All cabling should meet
national and local fire system installation regulations, e.g. FP200 type cable for high integrity installations.
Where the PSU is used for other applications, it should be installed according to all relevant safety regulations
applicable to that application.
Where the GEN PSU Fault and EPS Fault outputs are used, they should only be connected to circuits having voltages
less than 60V dc.
Cable Sizing
1)
Mains input cable must be to the applicable standard with a 5A or greater current capacity, i.e. 0.75mm
2
nominal conductor area, having a minimum operating voltage of 300/500V ac.
2)
The low voltage output cable must be sized to carry the rated load current to the devices connected to the
PSU.
3)
All cabling should be securely fastened in position.
Mounting the Module
4)
Fix the module into the chosen enclosure using 3 x fixing points as per Fig 1 (all fixings must be used).
Ensure sufficient space for heat dissipation and adequate ventilation to avoid overheating of the unit or
associated batteries.

OMMISSIONING
Mains Power Up
1)
With no external connections made to the PSU, connect the mains input wires to the terminal block,
ensuring that the mains isolator (disconnect device) is open
. Fasten wiring in place with cable tie to
saddle.
Note: Equipment must be earthed.
2)
Apply mains input. Confirm that all LED indicators flash on briefly proving integrity of indicating circuits.
Ensure that the green Mains LED then stays illuminated and that the yellow Fault LED flashes after
approximately 3s (indicating a disconnected battery).
3)
Disconnect the mains power.
Load Output and Remote Signalling
4)
Connect the EPS and GEN PSU Fault outputs to the appropriate inputs of control equipment if remote fault
monitoring is required.
5)
Connect the load (output) wiring as shown in Figure 2.
