3.4 Using a Clamp-On Sensor (Option)
Connect the clamp-on sensors to the product first, and then
to the active lines to be measured. Observe the following to
avoid electric shock and short circuits.
• Clamp sensor should only be connected to the secondary
side of a breaker, so the breaker can prevent an accident if
a short circuit occurs. Connections should never be made
to the primary side of a breaker, because unrestricted cur-
rent flow could cause a serious accident if a short circuit
occurs.
• When the clamp sensor is opened, do not allow the metal
part of the clamp to touch any exposed metal, or to short
between two lines, and do not use over bare conductors.
• To prevent damage to the product and sensor, never con-
nect or disconnect a sensor while the power is on.
• The current input terminals of the 3169-20/21 are not insu-
lated. To avoid the risk of electric shock, only use the spec-
ified optional clamp-on sensor.
