2.5.1 Connecting ac Power to the 980 Flow Meter
DANGER
When high-voltage power is
applied to the flow meter,
provisions must be made for
disconnecting external power to
the flow meter during servicing.
DANGER
Si du courant à haute tension doit être appliqué aux débitmètre, il est nécessaire
de prévoir un moyen de débrancher l'alimentation électrique externe du
débitmètre au cours de la maintenance.
PELIGRO
En caso de aplicarse una alimentación de alta tensión al medidor de flujo, deben
tomarse las precauciones necesarias para desconectar la potencia externa al
medidor al realizar el servicio.
GEFAHR
Soll den Strömungsmessern Hochspannungsstrom zugeführt werden, ist dafür
zu sorgen, daß während der Wartung die externe Stromversorgung
unterbrochen ist.
PERICOLO
Se l'alimentazione al misuratore di portata viene effettuata con alta tensione
deve essere installato un dispositivo di interruzione dell'alimentazione esterno
per scollegarlo quando è in servizio.
