Step 4 - Install Load circuit breakers (if required)

Ignore this Step if the load MCBs are already fitted.

 The current rating of the MCBs must be derated to 75%.

 The APS can use either Chint or Schneider circuit breakers. However, Chint and

Schneider circuit breakers are not interchangeable. When replacing existing circuit

breakers or fitting new ones, use the type that is already in use (see Spare Parts on page

70 for ordering details).

1 Remove the dc distribution front cover and top cover (if fitted).

2 Fit the load MCBs onto the load tooth-comb bus (start at the right-hand end) and

clip onto the DIN rail. Tighten the bottom MCB terminals.

3 Cut the load fuse fail detect wires (from the fuse

fail alarm board on the APS) to the correct length to

reach the MCBs.

 There is one load fuse fail detect wire for each load

MCB. These wires are thinner than the battery

fuse fail detect wires.

4 Connect the wires to the top terminals of the MCBs

and tighten terminal to hold the wire in place.

5 Fit MCB blanks to cover any unused positions.

6 Switch OFF all MCBs.
