Electrical Installation
P ower Source
These monitors are designed to operate from a single-phase
power source having one of its current-carrying conductors at
or near earth ground (the neutral conductor). Only the line
conductor is fused for over-current protection. Systems that
have both current-carrying conductors live with respect to
ground (such as phase-to-phase on multiphase systems) are
not recommended as power sources. A protective ground
connection by way of the grounding conductor in the power
cord is essential for safe operation.
NOTE
When power is supplied, line voltage will be
present in the instrument, even if the
POWER switch
is set to
STANDBY.
