Remark:
1. Prior to connecting the power distribution system to the UPS, make sure the
rated triploid-pole over-current breaker is installed to break off all the input lines
and the N line breaker can be congured individually.
2. When single-phase current exceeds 100A, switches of protective atmosphere
should be equipped with arc control devices,It should be D-curve air switch with
UL certication according to the customer requirement;
3. Battery positive/negative/N wire size: indicates UPS and battery bank wire size;
red wire signies the positive polarity and black wire the negative, while blue wire
the neutral.
4. There should be the same length of the battery wires (positive, negative and N)
of being no more than 40m.

3.5 Parallel UPS installation

1. Redundancy introduction
N+X is currently the most reliable power supply structure, in which N indicates the
minimum UPS number required for the total load and X is the redundant UPS number,
namely, the malfunctioning UPS number that the system can simultaneously bear. The
larger X is, the higher reliability of system will be. For instance, if the total loads of a
customer register 55kVA, we can use Castle 20KS for N+X design. With N taking up 3,
X can be selected in accordance with reliability degree or cost requirement. Supposing
customer selects X=2 and equalized UPS power supply is 11kVA for each unit, when one
set of UPS breaks down with malfunction, the remaining four sets will provide power
with almost 14kVA equalized current; if two sets of UPS fail, the remaining three sets of
UPS are supposed to provide power supply with almost 18kVA equalized current. The
maximum allowance of this system is for two sets of UPS going down at the same time,
the chances of which are much smaller than those of one UPS malfunction. Therefore, the
reliability degree can be largely enhanced, making it an optimal mode for application in
locations where high degree of reliability is always a focus.

15
2. EX33 Series UPS is capable of direct parallel connection, which only requires
the parallel connection wires (optional) for 2 to 8 sets of UPS in parallel connection in
order to realize power redundancy (N+X)(60KS/80KS support six sets of UPS parallel
connection). Ventilation spacing between machine anks should be a minimum of 10cmˈ
input wiring for each set of UPS should follow the requirements for that of single unit.
Each UPS input/output should be connected to the same input patch board, from which
wires are distributed for load as illustrated in following gure:

Remark:
1˅Common battery pack is applicable in parallel configuration; each battery pack
should be of the same model and the same batch from the same manufacturer.
2) Requirement of output wiring length:
ķ When the lead from the output terminal of each set of UPS to the output patch
board is less than 20m, wire difference should be less than 20%;
ĸ When the lead from the output terminal of each set of UPS to the output patch
board is longer than 20m, wire difference should be less than 10%.

6.1 Power Feedback Module

Power feedback module is an optional spare part specially designed for EX33 series
to provide perfect solution for high BUS voltage by feeding back the regenerative energy
to the power system or battery. And it is applicable to special elds in complex industrial
environment with reliable operation and exible installation, such as high-speed elevators,
mining elevators, rolling mill, motor, tension control system of wind mechanism and
principle bearing drive system of lathes etc.

6.2 Transformer

When the UPS is applied to load devices, there might be disturbances or malfunctions
caused by the Neutral to Ground voltage. However, the installation of the special
transformer to the output will make the Neutral-to Ground voltage be less than 1V;
besides, the installation of the special transformer to the input will avoid three times of
harmonic of the power system and reduce disturbances, thus prevent the load devices
from disturbing by other devices connected to the power system. It is recommended to
connect the transformer to the input or output according to application requirements.
(Internal transformer for EX33 20KS/30KS/40KS-ISO models and external for EX33 60KS
80KS-ISO models; please refer to this manual for operation instructions).

32
6.3 Double Charge Boards

EX33 Series UPS is capable of improving the charge capability and speed by
battery capacity expansion. It is exible to install an additional charge board in parallel
connection with the standard charge board since there is space for double charge boards
reserved.

6.4 Temperature Sensor

For battery with short lifetime and being sensitive to temperature, the temperature sensor
can be used to detect the temperature change, enable the temperature compensation
function of charge voltage, the battery charge voltage will be adjusted automatically to
prolong the lifetime of the battery.

6.5 Dustproof Net

Dustproof net is an optional spare part specially designed

for Castle EX Series UPS to work in dust environment
(dust diameter no less than 1.0mm, especially metallic
and metalloid dusts) in order to upgrade UPS frontal
protection grade to IP51 with flexible installation and
maintenance.

33
6.6 IP21 Option

EX33 60~80K Series UPS adopts top perforation and top and bottom ventilation, it is
recommended to install the IP21 option to prevent objects with diameter larger than 12mm
and water drops.

 Chapter 7 Transportation, Maintenance and
Troubleshooting

Move UPS
Make preparation for UPS relocation according to the following steps.
Remark: special equipment (folklift) is needed for loading and unloading due to the heavy
weight of UPS.
1. Switch off all equipments connected to UPS.
2. Turn off UPS AC switch and battery pack switch.
3. Disconnect all wires from UPS terminal bay.

Maintenance
EX33 Series UPS requires minimum maintenance.
1. If battery is switched off, loaded equipments will not be covered for power-off
protection.
2. Under normal circumstance, batteries should be found in poor performance,
replacement should be done as soon as possible only by qualied personal with proper
training. Users are not allowed to replace without authorization.

Remark:
A. Prior to battery replacement, switch off UPS and remove it from AC.
B. Take off metallic articles such as rings and watches.
C. Use screw drivers equipped with insulated handles and do not place tools or
other metallic substances on the batteries.
D. Short circuit or reverse connection is forbidden for battery polarity connection.
3. It is not recommended to replace batteries individually. Complete replacement
should follow instructions given by battery suppliers.
4. Make sure UPS vent are properly ventilated and clean side frames and fan
vents from dusts every half a year (switch off AC and battery power prior to
cleaning).

35
Troubleshooting
Should maintenance prove necessary, the following steps should be followed :
1. Check if UPS input wiring is done properly.
2. Check if all air switches are tripped off.
3. Check if voltage input is within specied range.
