| NOTE : |
|
Two cables of 1 meter length with 1.5mm cross sectional area are provided. This corresponds to a total resistance of 0.026 ohms. The instruments are calibrated with this resistance and consequently the cable length must not be changed. If different length or resistances are required, please indicate while ordering. |
| INSTALLATION |
| The best performance is guaranteed if the following points are observed. |
| 1) Shunts may be mounted horizontally or vertically. Horizontal mounting gives the best heat dissipation. |
| 2) Utilize the full end block surface area. |
| 3) Ample ventilation should be provided. |
| 4) Busbar should be adequately rated, cleaned & coated with a thin layer of silicon grease applied to the contact surface area. |
| 5) Bolts and nuts must be carefully tightened. |
| CAUTION |
| Shunts are not insulated & protection against accidental contact may be necessary in order to comply with Health & Safety regulations. |
