Single Ups Installation - Njoy Balder Series User Manual

5.1. Single UPS installation

Installation and wiring must be performed in accordance with the local
electric laws/regulations and execute the following instructions by
professional personnel.
Step 1. Make sure the mains wire and breakers in the building are
enough for the rated capacity of UPS to avoid the hazards of
electric shock or fire.
NOTE!
Do not use the wall receptacle as the input power source for the UPS, as its rated
current is less than the UPS's maximum input current. Otherwise the receptacle
may be burned and destroyed.
Step 2. Switch off the mains switch in the building before installation.
Step 3. Turn off all the connected devices before connecting to the UPS.
Step 4. Prepare wires based on the following table:
Wiring specs: AWG / cross section(mm)
Model
Input
10 AWG
Balder 6000
2.59 mm
8 AWG
Balder 10000
3.26 mm
NOTE!
The cable for Balder 6000 should be able to withstand over 40A current. It is
recommended to use 10AWG or thicker wire for safety and efficiency.
The cable for Balder 10000 should be able to withstand over 63A current. It is
recommended to use 8AWG or thicker wire for safety and efficiency.
The selections for color of wires should be followed by the local electrical laws and
regulations.
Step 5.
Remove the terminal block cover on the rear panel of UPS. Then

Step 6. Put the terminal block cover back to the rear panel of the UPS.
NOTE 1:
Make sure that the wires are connected tightly to the terminals.
NOTE 2:
Please install the output breaker between the output terminal and the load,
and the breaker should be qualified with leakage current protective function if
necessary.
NOTE 3:
UPS model Balder 6000 and Balder 10000 does not have any internal batteries.
You need to add external battery cabinets if you need UPS to offer backup time.
WARNINGS
Make sure the UPS is not turned on before installation. The UPS
should not be turned on during wiring connection.
Make sure a DC breaker or other protection device between UPS
and external battery pack is installed. If not, please install it carefully.
Switch off the battery breaker before installation.
NOTE 1:
Set the battery pack breaker in "OFF" position and then install the battery pack.
NOTE 2:
If more than one battery cabinets are connected to the UPS, they must be identical
and they must contain the same number and type of batteries (it is preferable for the
batteries to be identical). Please make sure you correctly set charging current (see
parameter 17, page 26) and battery number in cabinet (see chapter 6.9, page 32)
