CONNECTION SCHEMES
The phases and a neutral conductor for measurement and power supply are
determined by an indicator and supplied to the device. The connecting wires of
the load phases are connected to the corresponding terminals 5–7 (L1–L3), and
the neutral conductor (N) to terminal 8.
For correct operation of ZUBR D6, it is enough to connect the neutral
conductor to one of the zero terminals (4 or 8).
Scheme 1. Option for connecting an RCD, a circuit breaker with zero
transit through the device to a three-phase load.
IMPORTANT. Before the installation and operation of the device, please
read by the end of this document. This will help to avoid possible danger,
mistakes and misunderstandings.

INSTALLATION
The appliance is intended for installation inside residences. The risk of moisture or humidity in the installation site should be minimal. The ambient temperature during installation should be within –5…+45°С.
The device has additional overvoltage protection in the form of a varistor and a fuse. The appliance is installed in a special box, which allows to conduct the easy installation and operation. Cabinet should beequip ped with standard mounting rail 35 mm width (DIN rail). The appliance takes in width of standard module on 18 mm. The height of the appliance should be in the range 0,5…1,7 m from the floor
For protection against short circuit and excess capacity in circuit load necessarily need to set in front of the appliance, the automatic circuit- breaker ( at the schemes 1,2). The automatic switch off is established in the open-phase fault wire, as shown at the schemes 1,2 ( ). To protect person from electric shock leak is set safety shutdown device (at the schemes 1,2).
Terminals of the device designed for wire cross section 2up to 16 mm². It is advisable to use a soft wire, which is tightened in the terminals with a screwdriver with a tip width of no more than 6 mm with a torque of 2 4 Nm. A screwdriver with a blade more than 6 mm wide can cause mechanical damage to the terminals. Doing so will void your warranty claim.
