3.4 Installation notes
When installing the cabinet the space in front and back of the cabinet should be at least 100cm and
80cm respectively, for the convenience of operation and maintenance.
◆Please place the UPS in a clean, stable environment; avoid the vibration, dust, humidity,
flammable gas and liquid, corrosive. To avoid from high room temperature, a system of room
extractor fans is recommended to be installed. Optional air filters are available if the UPS
operates in a dusty environment.
◆The environment temperature around UPS should keep in a range of 0℃～40℃. If the
environment temperature exceeds 40℃, the rated load capacity should be reduced by 12％ per
5℃. The max temperature can't be higher than 50℃.
◆If the UPS is dismantled under low temperature, it might be in a condensing condition. The
UPS can't be installed unless the internal and external of the equipment is fully dry. Otherwise,
there will be in danger of electric shock.
◆Batteries should be mounted in an environment where the temperature is within the
required specs. Temperature is a major factor in determining battery life and capacity. In a
normal installation, the battery temperature is maintained between 15°C and 25°C. Keep
batteries away from heat sources or main air ventilation area, etc.
CAUTION!
Typical battery performance data are quoted for an operating temperature
between 20°C and 25°C. Operating it above this range will reduce the battery life
while operation below this range will reduce the battery capacity. Should the
equipment not be installed immediately it must be stored in a room so as to
protect it against excessive humidity and or heat sources.
CAUTION!
An unused battery must be recharged every 6 months temporarily connecting the
UPS to a suitable AC supply mains and activating it for the time required for
recharging the batteries.

Keatec C Series UPS 50 - 300 kVA 1.0 PF 208 Vac 3Ph Users Guide English 20190615 Page 13
CAUTION!
The highest altitude that UPS may work normally with full load is 1500 meters. The
load capacity should be reduced when this UPS is installed in place whose altitude is
higher than 1500 meters, shown as the following table:
(Load coefficient equals max load in high altitude place divided by nominal power of the UPS)

The UPS cooling is depending on internal fans and should be kept only in an area with good air
ventilation. There are many ventilation holes front and rear, they should not be blocked by obstacles.
3.5 External Protective Devices
For safety reasons, it is necessary to install, external circuit breaker at the input A.C. supply and the
battery. This chapter provides guidelines for qualified installers that must have the knowledge of
local wiring practices for the equipment to be installed.
◆External Battery
The UPS and its associated batteries are protected against the effect of over-current through a DC
compatible thermo-magnetic circuit-breaker (or a set of fuses) located close to the battery.
◆UPS Output
Any external distribution board used for load distribution shall be fitted with protective devices that
may avoid the risk of UPS overloaded.
◆Over-current
Protection device shall be installed at the distribution panel of the incoming main supply. It may
identify the power cables current capacity as well as the overload capacity of the system.
3.6 Power Cables
The cable design shall comply with the voltages and currents provided in this section and must
follow local wiring practices. Take into consideration the environmental conditions.
WARNING!
DURING STARTUP ENSURE THAT YOU ARE AWARE OF THE
LOCATION AND OPERATION OF THE EXTERNAL ISOLATORS WHICH
ARE CONNECTED TO THE UPS INPUT / BYPASS SUPPLY OF THE
MAINS DISTRIBUTION PANEL. ENSURE ALL POWER SUPPLIES ARE
ELECTRICALLY ISOLATED AND POST ALL NECESSARY WARNING
SIGNS TO PREVENT INADVERTENT OPERATION

CAUTION!
Protective earth cable: Connect each cabinet to the main ground system.
For Grounding connection, follow the shortest route possible .
3.7 Power cable connect
Before equipment has been installed, must comfirm the input source type, common input or Split
input, if the input source is dual input, must remove the copper bar that connected bypass and
mains.
Once the equipment has been finally positioned and secured, connect the power cables as
described in the following procedure.
Verify the UPS is totally isolated from its external power source and also all power isolators of the
UPS are open. Check to see if they are electrically isolated, and post any necessary warning signs
to prevent their inadvertent operation.
Open the UPS terminal panel; remove the cover of terminals for wiring easily.

Keatec C Series UPS 50 - 300 kVA 1.0 PF 208 Vac 3Ph Users Guide English 20190615 Page 18
Choose appropriate power cable. (Refer to the table above) and pay attention to the diameter of the
connection terminal of the cable that should be greater than or equal to that of the connection poles;
Wiring
WARNING!
If the load equipment is not ready to accept power prior to the arrival of
the commissioning engineer then ensure that the system output cables
are isolated safely.
Connect the safety earth and any necessary bonding earth cables to the
copper earth screw located on the floor of the equipment below the power
connections. All cabinets in the UPS must be grounded properly.
CAUTION!
The earthing and neutral bonding arrangement must be in accordance with
local and national codes.
3.8 Battery connection
The UPS adopts positive and negative double battery framework, total 16 (optional 18/20/22/24/26)
in series. A neutral cable is retrieved from the joint between the cathode of the 8th (9th/10th/11
th/12th/13 th) and the anode of the 9th (10th/11th/12 th/13th/14 th) of the batteries. Then the neutral cable,
the battery Positive and the battery negative are connected with the UPS respectively. The battery
sets between the Battery anode and the neutral are called positive batteries and that between
neutral and cathode are called negative ones.

Keatec C Series UPS 50 - 300 kVA 1.0 PF 208 Vac 3Ph Users Guide English 20190615 Page 19
The BAT+ of the UPS connect poles is connected to the anode of the positive battery, the BAT-N is
connected to the cathode of the positive battery and the anode of the negative battery, the BAT- is
connected to the cathode of the negative battery.
Factory setting is battery quantity 22pcs, battery capacity 12V100AH (charger current 15A). When
connecting 16/18/20/24/26pcs batteries, please re-set desired battery quantity and its capacity after
UPS starts at AC mode. Charger current could be adjusted automatically according to battery
capacity selected. All related settings can be done through LCD panel or monitoring software
WARNING!
Ensure correct polarity of string connections to the Battery Circuit
Breaker and from the Battery Circuit Breaker to the UPS terminals.
Ensure (+) to (+) / (-) to (-) but disconnect one or more battery cell links
in each tier. Do not reconnect these links and do not close the battery
circuit breaker unless authorized by the commissioning engineer.
CAUTION!
Ensure correct polarity of battery string series connection. Ensure inter-
tier and inter block connections are from (+) to (-) terminals. Do not
mix batteries of different capacity, different brands, or new with old
batteries.
3.9 UPS Parallel Installation
The basic installation procedure of a parallel system comprising of two or more UPS modules is the
same as that of single module system. The following sections introduce the installation procedures
specified to the parallel system.
3.9.1 Cabinet installation
Connect the UPS to be put into parallel system following the example below.
