Electrical Installation
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.
WARNING.
When power is supplied, line voltage will be present in the instru-
ment, even if the
POWER
switch is set to
STANDBY.
