When there are discrepancies between the labels 

and the instructions in this manual, the labels on the 

unit will always take precedence.

•

References 

in bold in brackets

 that appear in the different 

sections of this chapter, correspond to elements of the UPSs 

identified in their respective user manual. For more informa-

tion, consult this document.

5.3.1.  Connection of the bypass panel power. UPS input line 

(rectifier)

•

The earth connection must be connected to the ter-

minal identified with the 

( )

 label, ensuring that this 

is done before supplying input voltage to the bypass panel.

•

Connect the bypass panel input line power cables to the ter-

minals indicated as “INPUT LINE”, respecting the order of the 

phase (R) or phases (R-S-T) and neutral (N), indicated on the 

unit’s labels and in this manual.

It is essential to have a neutral (N).

5.3.2.  Connection of the bypass panel power. Static bypass 

line (only on -B panels).

•

The earth connection must be connected to the ter-

minal identified with the 

( )

 label, ensuring that this 

is done before supplying input voltage to the bypass panel.

•

Connect the bypass panel’s static bypass line power ca-

bles to the terminals indicated as “STATIC BYPASS INPUT 

LINE”, respecting the order of the phase (R) or phases (R-

S-T) and neutral (N), indicated on the unit’s labels and in 

this manual.

It is essential to have a neutral (N).

5.3.3.  Connection of the UPS to the bypass panel

•

Connect a cable bundle between the set of terminals identi-

fied as “UPS INPUT” on the bypass panel and the UPS input 

terminals identified as “INPUT”, respecting the order of the 

phase (R) or phases (R-S-T) and neutral (N), indicated on the 

unit’s labels and in this manual. 

•

On units with a separate static bypass line, connect a cable 

bundle between the set of terminals identified as “STATIC BY-

PASS INPUT” on the bypass panel and the UPS input terminals 

identified as “STATIC BYPASS”, respecting the order of the 

phases (R-S-T) and neutral (N), indicated on the unit’s labels 

and in this manual.

•

Connect a cable bundle between the set of terminals iden-

tified as “UPS OUTPUT” on the bypass panel and the UPS 

output terminals identified as “OUTPUT”, respecting the 

order of the phase (R) or phases (R-S-T) and neutral (N), 

indicated on the unit’s labels and in this manual.

5.3.4.  Connection of the loads to the bypass panel

•

The earth connection must be connected to the ter-

minal identified with the 

( )

 label, ensuring that this 

is done before supplying input voltage to the bypass panel.

•

Connect the loads to the set of terminals identified as 

“LOADS OUTPUT” on the bypass panel, respecting the 

order of the phase (R) or phases (R-S-T) and neutral (N), 

indicated on the unit’s labels and in this manual.

5.3.5.  Connection of the auxiliary contact of the UPS 

manual bypass switch to the bypass panel

•

The terminals identified as “BYPASS AUXILIARY CON-

TACT” on the UPS must be connected to those on the 

bypass panel using control cables (minimum 1 mm

2

 and max-

imum 2.5 mm

2

). These signal terminals are the extension of the 

normally open auxiliary contact of the respective internal 

manual bypass switch.

The auxiliary terminals of the UPS are identified as follows, 

depending on the product series:

ˆ

ADAPT, ADAPT-X, pins

 1 

and

 2 

of

 (JP5)

.

ˆ

ADAPT2, pins 1 and 2 of 

(IDIG3)

.

ˆ

CUBE3+, 2-terminal strip 

(X51)

.

ˆ

CUBE4, 2-terminal strip 

(IDIG3)

.

ˆ

X-PERT, terminals 

(X10-1), (X10-2)

.

ˆ

X-TRA, terminals 

(MBY-1)

 and 

(MBY-2)

.

ˆ

TWIN PRO, 2-terminal strip 

(EMBS)

.

•

This connection is a safety lock against unwanted or erro-

neous operations, which, without it, would lead to faults on 

the UPS and/or in the loads supplied by it, as it transfers the 

inverter to “OFF” when switching any of the manual bypass 

switches to “ON”.

5.3.6.  Connection of the auxiliary contact of the UPS output 

switch to the bypass panel (only available on panels 

from the SLC CUBE3+ and SLC CUBE4 series).

The output switch on each UPS has a normally open auxiliary 

contact with a cable connected as a bridge 

(PT)

 that closes 

its circuit respectively on terminal strip 

(X45)

 on CUBE3+, 

on terminal strip 

(IDIG4)

 on CUBE4 30-80 kVA, between the 

terminals on strip

 (XAUX-1)

 and 

(XAUX-2)

 on X-TRA, or be-

tween terminals 

(X10-5)

 and 

(X10-6)

 on X-PERT. 

On CUBE4 7.5-20 kVA models, the output switch does not 

have an auxiliary contact, but it does have the auxiliary con-

tact signal of the external output switch between terminals 5 

and 11 or 9 on the INPUT SIGNAL terminal strip.

•

Remove it and, using control cables (minimum 1 mm

2

 and 

maximum 2.5 mm

2

), connect the terminals identified as 

“OUTPUT AUXILIARY CONTACT” on the UPS 

(X45)

, 

(IDIG4) 

and (between terminals 

5 and 11 or 9 INPUT SIGNAL

) to 

those on the bypass panel. Both terminals are the extension 

of the normally open auxiliary contact of the respective 

output switch. 

The purpose of this connection is none other than to activate 

the alarm on the control panel due to accidental tripping or 

voluntary/involuntary switching to “OFF” of either of the two 

output switches (on the UPS or the panel).
