Salicru SLC ADAPT, User Manual

13

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 

(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)

.

•

The way to connect the UPS control cables to the panel will 

vary depending on its series, as will the number of termi-

nals available on the control strip:

ˆ

CUBE3+ and CUBE4.
Make the parallel connection between the auxiliary 

contacts of the manual bypass switch on each unit and 

those on the bypass panel (see Fig. 5 and 7).

ˆ

ADAPT, ADAPTX, pins 1 and 2 of JP5, ADAPT2, pins 1 

and 2 of IDIG3, TWIN PRO2, X-TRA and X-PERT.
The manual bypass switch on the panel will have as many 

auxiliary contacts extended to the control strip as numbers 

of UPSs to be connected in parallel (see Fig. 6 and 8).

Connect the terminals of the panel strip to each UPS 

of the parallel system respectively. These connections 

must never be joined

, as internally, each UPS has dif-

ferent masses.

As stated earlier, this connection is a safety lock against 

unwanted or erroneous operations.

Manual bypass panel for “n” standard parallel or redundant UPSs, for UPS series CUBE3+, CUBE4 and TWIN PRO 2.

5.3.7.3.  Connection between the auxiliary contact of the 

output switch on each UPS and those of the bypass 

panel (only available on panels from the SLC CUBE3+, 

SLC CUBE4, SLC X-PERT and SLC X-TRA 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 ter-

minal strip 

(IDIG4)

 on CUBE4 30-80 kVA, between the terminals 

on strip

 (XAUX-1) 

and 

(XAUX-2)

 on X-TRA, or between termi-

nals 

(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 contact signal 

of the external output switch between terminals 5 and 11 or 9 on 

the INPUT SIGNAL terminal strip. . 

•

Remove it on each unit and, using control cables (minimum 

1 mm

2

 and maximum 2.5 mm

2

), connect the terminals identi-

fied as “OUTPUT AUXILIARY CONTACT” on each UPS 

(X45)

, 

(IDIG4)

, (between terminals 

5 and 11 or 9 INPUT SIGNAL)

, 

(XAUX-1)

 and 

(XAUX-2)

 or 

(X10-5)

 and 

(X10-6)

 to the re-

spective terminals on the manual bypass panel, paying at-

tention to the correlative order of each one. 
That is to say, the “OUTPUT AUXILIARY CONTACT” terminals 

(X45)

, 

(IDIG4)

, (between terminals 

5 and 11 or 9 INPUT 

SIGNAL

), 

(XAUX-1)

 and 

(XAUX-2)

 or 

(X10-5)

 and 

(X10-6) 

on 

UPS no. 1 to the terminals on auxiliary strip “OUTPUT 1 UPS”, 

the “OUTPUT AUXILIARY CONTACT” terminals 

(X45)

, 

(IDIG4)

, 

(between terminals 

5 and 11 or 9 INPUT SIGNAL

), 

(XAUX-1)

and 

(XAUX-2)

 or 

(X10-5)

 and 

(X10-6)

 on UPS no. 2 to the termi-

nals on auxiliary strip “OUTPUT 2 UPS” and so on according to 

the number of units that make up the system.
