6.  OPERATION

This section describes the basic procedures for starting the 

UPS, with start-up being understood as reaching the normal 

operating mode described in section 4.5, specifically in "4.5.1 

Normal mode". That is, "online" or double conversion mode, to 

achieve maximum protection for critical loads.
Additional procedures are also described, understanding that 

these should only be carried out exceptionally due to a unit 

shutdown, maintenance, changes in the installation, faults, etc.
All procedures will consider an installation whereby there is a 

control panel that is external to the UPS, highly recommended 

for facilitating interventions and maintenance, equipped with 

the following:

•

Switch for UPS input voltage.

•

Switch from the UPS output to the loads.

•

Switch corresponding to the UPS maintenance bypass, with 

its auxiliary contact wired to the corresponding terminal 

(

IDIG3 

see

Table 2

) of the unit's interface.

•

Optionally, on units with a separate static bypass line, a 

switch for this line is also present on the panel.

6.1.  UPS START-UP

6.1.1.  Checks before start-up

Read the technical documentation 

Before isolating and starting the unit, all instructions 

contained in this manual and in the technical support documen-

tation must be read and understood. 
Before starting the unit:

•

Make sure that all connections have been made correctly 

and with sufficient torque, observing the unit's labelling 

and the instructions in chapter 5. 

•

Check that the unit's input, bypass and output disconnect 

switches/switches and the control panel external to the 

UPS are in the "Off" position. 

•

Check that the internal battery disconnect switch and/or 

the external cabinet are in the "Off" position. 

•

Make sure all loads are switched off (set to "Off"). 

•

It is very important to proceed according to the order estab-

lished in the following procedures of this section.

•

Before starting the unit, check that: All installation and 

electrical connection tasks have been carried out by duly 

qualified technicians. 

•

All power and control cables have been connected correctly 

and firmly to the corresponding terminals.

•

With regards to external boards or panels, it is very impor-

tant to wire the auxiliary contact of the maintenance by-

pass switch, and the auxiliary contact of the output switch 

for parallel systems, to the corresponding connector of the 

unit.

•

The earth cable is connected correctly. 

•

The battery polarity is correct and the voltage is within the 

operating values. 

•

The phase rotation (phase sequence) of the AC input line 

is correct and the voltage is within the tolerance of the op-

erating values. The same applies for the separate bypass 

line, if any.

•

The emergency stop circuit (EPO), if installed, is not acti-

vated (a wire bridge is supplied in the unit, connected by 

default to the terminals of this connector, which allows 

normal operation).

6.1.2.  Initial start-up

The initial start-up of the UPS after reception and installation 

has certain specificities. For normal or periodic start and stop 

operations, refer to sections 

6.1 and 6.2

, respectively.

The initial start-up must be carried out by authorised 

staff (

T.S.S.

 or the distributor). This operation activates 

the start of the product's warranty, and as well as the start-up, 

the qualified technician will also carry out additional checks 

and calibrations "in-situ" that are not described in this manual. 
Once all checks described in 

6.1.1

 have been carried out, pro-

ceed to:

1. 

Check, once again, the correct connection of the 

phases and neutral

to the unit's input, as well as that of 

the separate static bypass line, if any. In the event of incor-

rect connection or phase rotation, correct it. 

2. 

Supply general voltage to the control panel external 

to the UPS.

3. 

Set the switch corresponding to the UPS input on the 

control panel to "On".

4. 

Set the input switch of the UPS to "On" (Q1). The "Initial 

Settings" ("Ajustes iniciales") screen appears

, see 

Fig.

, if it is really the initial start-up of the UPS, in English by 

default. Otherwise, the unit is already configured according 

to the installation and you can refer directly to section 

6.1.3
