AC Input and Output Connections

DANGER
HAZARD OF ELECTRIC SHOCK, EXPLOSION, OR ARC FLASH Before connecting the PowerLogic™ DVR system, make sure that the lines connected between upstream connection switchgear to the system inlet are isolated. Installation and wiring must be performed by qualified personnel only. Make sure that all the switches of the PowerLogic™ DVR system are open or in the OFF position. Place warning signs to avoid accidental operations. Make sure that the wires used to connect the mains and circuit breakers in the building have specific rated capacity as required for the equipment to avoid hazards of electric shock or fire. Ground the equipment using the ground connecting point provided before turning on the power supply to the system. Before doing the electrical connection for the PowerLogic™ DVR units and manual bypass cabinet, make sure that there is no voltage in the line to avoid any possible electrical risk to personnel. Follow all local and national safety regulations provided in the installation manual. Failure to follow these instructions will result in death or serious injury.

Failure to follow these instructions will result in death or serious injury.

The PowerLogic™ DVR system has 3-phase grid AC input and 3-phase AC output. The connections are accessible at the front of all cabinets through the holes of diameter 13 mm. The information of the input and output connections are available on the labels at the bottom of the cabinet doors.

NOTE:

The neutral is not used inside the PowerLogic™ DVR units. The neutral terminals placed on the manual bypass cabinets are used to make the connection between the system input and system output.

Apply tightening torque of 34 N•m to the screws used for the input/output AC cable for PowerLogic™ DVR units and manual bypass cabinets.

NOTICE
RISK OF EQUIPMENT DAMAGE For IT grounding systems, the ground connection to the EMI filter should be disconnected and removed to avoid any damage to the EMI filter when the first grounding fault occurs (Refer IT Grounding System ). Failure to follow these instructions can result in equipment damage.

Follow the steps to provide the connection between PowerLogic™ DVR system and manual bypass cabinet:

Connect the protective earth cables (the cable coming from the system INPUT and the cable going to the system OUTPUT) to the ground terminal of the manual bypass cabinet.
Connect the protective earth cables between the ground terminal of the manual bypass cabinet and the ground terminal of each PowerLogic™ DVR unit.
Connect the input wires of the system to INPUT L1 (R), L2 (S), and L3 (T) connecting terminals of the manual bypass cabinet (refer cable no. in image Electrical Connections).

NOTE: Make sure that the phase sequence of the wires is connected as per the instruction.
Connect the output wires of the system to OUTPUT L1 (R), L2 (S), and L3 (T) connecting terminals of the manual bypass cabinet (refer cable no. in image Electrical Connections).

NOTE: Make sure that the phase sequence of the wires is connected as per the instruction.
Connect the input wires of each PowerLogic™ DVR unit between DVR INPUT L1 (R), L2 (S), and L3 (T) connecting terminals of the manual bypass cabinet and INPUT L1 (R), L2 (S), and L3 (T) connecting terminals of each PowerLogic™ DVR unit (refer cable no. in image Electrical Connections).

NOTE: Make sure that the phase sequence of the wires is connected as per the instruction.
Connect the output wires of each PowerLogic™ DVR unit between DVR OUTPUT L1 (R), L2 (S), and L3 (T) connecting terminals of the manual bypass cabinet and OUTPUT L1 (R), L2 (S), and L3 (T) connecting terminals of each PowerLogic™ DVR unit (refer cable no. in image Electrical Connections).

NOTE: Make sure that the phase sequence of the wires is connected as per the instruction.

NOTE:

The input and output cables of the system can be connected at the top or bottom of the manual bypass cabinet.

The input/output cables of PowerLogic™ DVR unit can be connected only at the bottom of the cabinet.

NOTICE
RISK OF EQUIPMENT MALFUNCTION Manual bypass cabinet has neutral terminals both at the top and bottom. The power connection of the input neutral (going to the source) and the output neutral (going to the load) must be connected to the same terminal. The power cables (3 phases and ground) between the manual bypass and each of the inputs/outputs of PowerLogic™ DVR units are not provided. These cables must have the same length and section to maintain the current sharing between PowerLogic™ DVR units. Failure to follow these instructions can result in equipment damage.
