As the front of the enclosure conforms to IP54 it is protected from water spray from all directions, additional protection to the panel may be obtained by the use of an optional panel gasket. The terminals at the rear of the product should be protected from liquids. The instrument should be mounted in a reasonably stable ambient temperature and where the operating temperature is within the range -10 to 55 C .
3. To protect the product against permanent damage, surge transients must be limited to 2kV pk. It is good EMC practice to suppress differential surges to 2kV at the source. The unit has been designed to automatically recover in the event of a high level of transients.
11.4 Auxiliary Supply instrument 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. 11.5 Fusing It is recommended that all voltage lines are tted with 1 amp HRC fuses. 11.6 Earth/Ground Connections For safety reasons, CT secondary connections should be grounded in accordance with local regulations.
