second rechargeable battery.

e. Connectors B3a and B3b are not used.

6. Cable set G:

a. Attach connector G1 on the PS-interface labbeled

RTH.

b. Route the cable across the temperature sensor

bracket so that the temperature sensor G2 hangs

approximitely 5 cm (2 in.) above the rechargeable

batteries.

7. Pre-assembled cable set 12:

a. Connect the 2-pin plug 13 on the interface AC of the

power supply.

8. Pre-assembled cable :

a. Connect the loose ends of the cover tamper switch to

the 2-pin screw connector on the top of the AMC.

Position the cable in the space between the housing

and the mounting rail.

DANGER!

Remove the fuse from the three-pin connector before

proceeding with the power supply connection.

Do not install the fuse before completing the installation

procedure.

9. Connect the main AC supply X:

a. Connect the brown (phase) wire to terminal L1.

b. Connect the blue (neutral) wire to terminal N.

c. Connect the grounding cable to the housing at

position 11.

CAUTION!

Shorten the external supply wires so that the ground (yellow/

green) wire is at least 20 mm (0.8 in.) longer than the live (blue

!

and brown) wires. This ensures that the ground wire cannot be

accidentally disconnected before life wires.
