◗

the power cables for the connections

between cubicles are not supplied;

◗

open the doors and remove the

lower terminal shields (secured by
screws to the cubicle chassis) of the
rectifier-inverter and Static Switch
Cubicles;

◗

connect the cables shown in heavy

lines in the wiring diagrams shown
previously to the terminals specified in
the figures below;

◗

each cubicle must be earthed;

◗

the routing of the power cables is

shown in the figures;

◗

the auxiliary wiring is routed in

troughs located nearby (not shown in
the drawings);

◗

outside the cubicles, separate the

auxiliary wiring from the power cables;

◗

all the cubicles must be

interconnected for earthing, forming a
mesh which is itself connected to the
building structure and earthing
electrode;

◗

the connection drawings hereafter

show the cubicles with doors open and
terminal shields removed.

Before making connections, check that
switches Q1, Q4S, Q3BP and Q5N are
in the "open" position (toggle opposite
the "O" mark).

◗

in the case of parallel-connected

rectifier-inverter cubicles with SSC,
switches Q4S and Q3BP are not
included and mains 2 is connected to
the Static Switch Cubicle. The other
connections are the same;

◗

for modular UPSs with an external

maintenance bypass, switch Q3BP
must be locked open;
