5. N+1 REDUNDANCY
Two or more SRxxx series power supplies may be connected in parallel for increased power (with or without diodes). It is essential
that the wiring from each unit to the load is kept identical for equal power sharing particularly when diodes are not used.
6. CONNECTION NOTES

Two outputs connected in parallel internally are provided.

If used as a battery charger ensure that the battery polarity matches the power supply output.

Alarms can be tested by using an external variable voltage supply.
