the longest one.
Output
The N wires of all the UPS units must be connected. The shortest cable between each UPS and the power
source shall be greater than 95% of the longest one. The measurements start from the output node of the
UPS.
Dual power supply
The rectifier input and bypass input are separate power supplies. The power supply must use a common N
wire.
Battery connection
In the case of parallel use of Santak 3C3 HD 20-80K, both common battery and separate battery configura-
tions are supported among the cabinets. Please see Section 4.2.1 for information about supporting common
battery configuration.
Installation of parallel system, signal wires of parallel system and CAN communication
control wires
•
In a parallel system, the electric line from the input of each UPS to the common point
of the AC power source shall be identical with that from the output to the common
point of the load in length. The length shall meet the following regulations to ensure
that the input resistance and output resistance of each UPS matches each other, and
resistance error shall be controlled within ±10%. The purpose is to ensure current
sharing of parallel UPS. It's advised that the input and output cables of the parallel
system are longer than 10m in total, 5m for either input or output.
•
Total length 1A=2A=3A=4A
•
If only two UPS units are connected in parallel (redundancy), the above requirements
are not mandatory, but the future expansion might be affected if the requirements are
not satisfied.
•
Ensure that the static bypass input of each UPS in the parallel system is the same
common point, like an external bypass circuit breaker. If the rectifier input of each
UPS in the parallel system is a separate power source, please consult Santak
engineers to ensure the compatibility of power distribution.
