5.2.7.2. COM or USB port. Connector (X31
Basically is a RS232 communication through a physical con-
•
nection of a USB connector. USB and DB9 of the RS232/RS485
can not be used simultaneously because they are mutually ex-
clusive, with the USB as a priority.
As well as the RS232/RS485 port, it is a serial data transmis-
•
sion and it is used to connect the UPS with any machine or
device with USB connector.
When connecting the UPS to an IT equipment, the driver in-
•
stalled in the IT device is started automatically, being able to
establish the communication between both USB ports. Notice
that this process takes its time, because it depends on dif-
ferent external factors (IT equipment, internet line,...).
In case the driver was not found in the IT equipment, go to the
following website, and find the needed driver in section "VCP
Drivers", download it and install it:

Communication protocol.
•
The used communication protocol is «MASTER/SLAVE» type.
The computer or IT system («MASTER») asks about a particular
data, and the UPS («SLAVE») answers with the required data.
In case this communication was required to connect an equip-
ment, ask for the IN467*01 protocol.
Firstly, the communication channel of the computer has to set
with the same parameters of the UPS communication channel.
Then, they will be ready to start the communication and there-
fore to send the first UPS question.
In case there was a problem in the communication, it is better
to repeate the sequence of initialization of the channel.
The communication parameters are:
•
Baud rate: 1200, 2400, 4800, 9600 or 19200 Bauds.
Information bits: 8 Bits.
Stop bits: 1 or 2 Bits.
Parity type: Even, Odd or None.
The base of the front door (PF) has a slot to allow the en-
•
trance of the communication cables from outside to the UPS.
Be careful to not trap them between the edges of the door and
the cabinet, when closing it.
5.2.8. EPO terminals (X50).
All UPSs have two terminals to install an external emergency
•
button to shutdown the output (EPO).
In case it was required to install a switch or button (EPO) in a
•
single equipment, the cable bridge that closes the circuit has
to be removed from terminal strip (X50) first.
For a parallel system, two different solutions can be applied,
•
which are the following:

).
Connect the button (EPO) in only one equipment of the
USB
parallel system. Remove the cable bridge from termi-
nals (X50) in the equipment that it is only connected.
In case of fault and removing of the equipment that has
physically connected the button (EPO), there is the risk
of leaving the system without the emergency stopping,
unless it is reconnected to the other operative UPSs.
Connect a button (EPO) to each equipment of the par-
allel system. To do that, remove all the cable bridges
from terminals (X50) in each equipment.
Therefore, the functionality of the (EPO) will be kept in
each one of them, regardless what occurs in the rest of
equipments of the parallel system.
By means of the own communication BUS among the equip-
ments that make the parallel system, any action over any
button will affect to the whole.
Fig. 38. Connection terminals for emergency shutdown switch or
button (EPO), belonging to the end/user.
In any case, the switch or button (EPO) has to be normally closed
•
(NC), so the emergency shutdown order will be triggered when
opening the circuit between these terminals (X50).
To restore the UPS to normal mode, invert the position of the
switch or button (EPO), -close the circuit between the termi-
nals (X50)-, unblock the button.
To know the operating of (EPO), see section 6.6. of this manual.
•
The base of front door (PF) has a slot to facilitate the en-
•
tering and way out of the communication cables inside the
UPS. Watch to not trap them between the door and cabinet
when closing it.
5.2.9. Auxiliary contact and battery temperature
probe terminal strip.
All the equipments are provided with terminal strip that cor-
•
responds to the auxiliary contacts of manual bypass (X51) and
output (X45) switches.
Also in the equipments either with separate battery cabinet
•
(models >20 kVA (LV) / >40 kVA (HV)) or in B1 equipments,
the additional terminal strip (X34) are supplied, to connect
the battery temperature probe that allows compensating
the floating voltage according to the ambient temperature.
Any wire connected to the terminals (X34), (X45) and
•
(X51), will be entered into the equipment through the cable
bushing (PR).
