5 Commissioning the System

5.1 General

All site preparation and equipment installation in the previous chapters must be completed before

commissioning.

• Ensure that the AC power source isolator is switched OFF.

• Switch all MX06 40A Shelf and any external battery circuit breakers to the OFF position.

5.2 Powering up the MX06 40A Shelf

• Set the required alarms to show a “Major” or “Minor” alarm. To do this remove the alarm card

from the shelf and operate switches SW2 and SW5 (see section 2.3.4)

• Switch on the external ac power supply to the MX06 40A Shelf.

• Check the Rectifier module LED’s:

• Check that each rectifier module has 2 green LED’s lit (if fitted), representing Input Healthy

and Output Healthy. There should be no red LED’s lit.

• Check the alarm card LED’s:

• The alarm card has 4 LED’s (3 red and 1 yellow) the only LED that may be lit is the red “Dist

Trip” which will be lit if the system has output circuit breakers that are turned off. The other

LED’s should be off unless “Major” or “Minor” have been allocated to “Dist Trip”.

• Set alarm card meter to read “Volts” and check that the output volts are set to the desired

level. If the voltage is slightly higher or lower than required simply adjust using the alarm card

front panel potentiometer (see section 2.3.1). If the output voltage is outside the specified

range this may indicate a fault.

• Switch on the Distribution Breakers (1, 2, 3 and 4 as required) if fitted.

• Ensure the correct polarity of any connected battery strings (see section 4.4.4) then switch on

any external battery breakers as required.

• Switch the “Battery Connection” switch to the desired setting “ON”, “AUTO” or “OFF” (see

section 4.4.2)
