Installation should be performed by qualified electricians only!
Make sure electrical service is disconnected before making any electrical connections.
MODEL
CTL-
Branch circuit protection is required to be provided in accordance with the National and Local codes of the
inspection authority.
Route wires as required and secure to terminals per connection diagram on this sheet and on the unit.
Transducers are suitable for installation on 600Vac lines.
To prevent contact with live circuits, when installed on a bare bus bar, the transducer is required to be
mounted in an enclosure that requires the use of a tool for access. When installed on an insulated cable this
second enclosure is not required.
OPERATING INSTRUCTIONS
1.
2.
3.
This unit is intended for indoor use at altitudes up to 2000 meters.
Transient overvoltages according to Installation Category (overvoltage category) II, pollution Degree 2.
If cleaning of the exterior surface is necessary, de-energize all services of supply (both measuring and
instrument power circuits) and brush with a soft brush or blow off with low-pressure air. Use appropriate eye
protection. Not suitable for hose-down cleaning.
Maximum relative humidity 80 percent for temperatures up to 31°C decreasing linearly to 50 percent relative
humidity at 40°C.
Maximum operating temperature range is -40°C to 65°C.
