4.4 Auxiliary Supply
EINE should ideally be powered from a dedicated supply, however it may be powered
from the signal source, provided the source remains within the limits of the chosen auxiliary
voltage.
4.5 Fusing
It is recommended that all voltage lines are fitted with 1 amp HRC fuse.
4.6 Earth/Ground Connections
For safety reasons, panels and accesoriess should be grounded in accordance
4.3 Wiring
Input connections are made directly to screw-type terminals with indirect wire pressure.
Numbering is clearly marked on the connector. Choice of cable should meet local regulations.

Terminal for inputs will accept up to 4mm (12 AWG) or 2.5mm (12AWG)Standard
Note :
1) It is recommended to use wire with lug for connection with meter.
2) For disconnecting the device a switch or circuit-breaker shall be included at the
site and shall be within easy reach of the operator. The specification are as below.
For aux. = At least 1.5 times of applied Power supply.
For Measuring Input = At least 1.5 times of applied measuring inputs.
