INSTALLATION & OPERATING MANUAL

Note that until AC power is applied to the system the controller will not activate the
LVD contactor.
12.6 System Turn-On
Perform the following operations:
1. Set the battery and all load circuit breakers to the OFF position.
For systems with GMT fuse distribution remove all fuses if already installed.
2. Plug in the rectier modules.
3. Connect the AC power cables to the AC source.
4. Check that the green LED on the front panel has lit. After approximately 20
seconds for initialization the MAJA LED at least will light. The RFA LED
may also light, dependent on the number of rectiers installed at the time.
5. Set the battery circuit breaker to the ON position. Then set the load breakers
to the ON position and/or insert the GMT fuses.
After approximately 5 seconds the status of various alarm LEDs will change,
dependent on the number of rectiers installed.
Using the WEB browser interface described in section 13 it is now possible to check
overall system status for correct operation.
In particular, it is important to ensure that the load current reading does not exceed
the maximum capacity of the installed rectiers or, where N+1 operation is required,
the maximum capacity of one less than the total number of rectiers installed. Note
also, that the system should have been sized so that a proportion of the available
rectier capacity is allocated for battery charging. Where N+1 redundant operation
is used the additional ‘spare’ rectier will normally provide this current.
IMPORTANT NOTES:
a) It is not possible to start the system by connecting the batteries alone.
b) During the 30 seconds initialization period the system bus voltage will be at the
factory preset level of the rectiers; nominally 54.4V, 27.2V or 13.6V depending
on system voltage. After this period the internal controller will lower the output
voltage by approximately 15% in order to limit current owing to the batteries.
During a following period of approximately 30 minutes the controller will ramp
the system voltage up to the correct oat voltage as determined by the temperature
compensation algorithm.
This ‘walk-in’ function can be disabled via the controller WEB interface if it not
required.
