This chapter primarily focuses on the installation of the UPS, covering various aspects such as unpacking and
inspection, cable selection, installation procedures, and electrical connections.
3.1 Unpacking and Checking
When unpacking the UPS, follow these steps:
• Examine the exterior for signs of shipping damage. If any damage is detected, promptly inform the carrier.
• Reviewthedeliverylisttoensure thatall accessoriesarepresent andaccurate.Ifthereareany inconsistencies,
contact the distributor without delay.
3.2 Installation Preparation
3.2.1 Select Breaker & Wires
When choosing AC input and output wires, DC input wires, and the appropriate breakers, it's crucial to base your
decisions on the maximum steady-state phase current of the UPS. For guidance, refer to the following tables:
• Table3-1 presents the maximum steady-state phase current for each operational mode.
• Table3-2 provides the rated current for recommended breakers.
• Table3-3 outlines the minimum recommended wire cross-sectional area.
To make your selections accurately, ensure to consult and match the specifications from Table3-1, Table3-2, and
Table3-3.
Table 3-1 UPS max. steady state phase current

AC output (A) 35 35 46 46 68 68 91 91
3.2.2 Select Input Breaker
We recommend incorporating a breaker (ideally with a feedback double pole disconnection mechanism) or a
distribution cabinet that aligns with the UPS power rating in front of the UPS input. This serves to isolate the
mains. In consideration of the UPS charging power and the initial power-on current surge, the chosen breaker
must have a current rating 1.5 to 2 times that of the maximum UPS input current. Importantly, this breaker
should not include leakage protection to prevent erroneous tripping.
When selecting the appropriate breaker, ensure it is rated for more than 250Vdc for the DC input. For precise
guidance, consult Table3-2 for breaker rated current recommendations.
Moreover, if opting for a distribution box, it's advisable to source one from Numeric, to have a seamless experience.
This will help ensure the reliability and safety of the setup.

3.2.3 Select Wires
To determine the appropriate wire cross-sectional area for AC input, output, and battery connections, refer to
the recommended values provided in Table3-3, Table3-4, and Table3-5. Please note that the suggested cross-
sectional areas are intended for use when the user is connecting wires for a length of approximately 5 meters.
If the length of the lead wire surpasses 20 meters, it's important to increase the cross-sectional area of the
conductor wire accordingly. This adjustment helps account for potential voltage drop and ensures efficient and
safe performance of the connections.
NOTE!
For the PREMIUS series UPS with capacities ranging from 7.5kVA to 20kVA, the UPS can
be configured in either 31 mode or 11 mode.
• In 31 mode, since the UPS is equipped with input and output three-phase connectors,
it's recommended to utilize single wires for bypass input and output connections.
• In 11 mode, the UPS doesn't feature input and output three-phase connectors.
Therefore, for AC input connections, it's recommended to use three wires. Please
be aware that when the UPS is operating with a single-phase input, the three phase
wires should be connected to the same phase of the power input. This helps ensure
proper functioning and safety.
