This product is not intended to be used for Life or Safety applications.
!
This product is not intended for use in any hazardous or classified locations.
Disconnect and lock out all power sources before installation as severe injury or death may result from electrical
shock due to contact with high voltage wires.
Installation
Make sure that all installations are in compliance with all national and local electrical codes. Only qualified individuals that are
familiar with codes, standards, and proper safety procedures for high-voltage installations should attempt installation. The
current sensor is a 2-wire Loop Powered device that requires a regulated +12 to 30VDC external power source.
The A/SCTA Series Analog Current Sensors should be used on Insulated Conductors Only! The current sensors may be
mounted in any position using the (2) #8 x 3/4" Tek screws and the mounting holes in the base or snapped directly on to the 35mm
DIN rail (See Figures 1 & 2 below). Leave a minimum distance of 1" (3 cm) between the current sensor and any other magnetic
devices such as contactors and transformers.
Latch Operation:
Pressing down on the two (2) side tabs and swinging the cover open opens the split core current sensor as shown in Figure 3
below. Lifting up on the latch with a flat-tip screwdriver as shown in Figure 4 below can also open the unit. Press down firmly on
the cover to close the current sensor. An audible "click" will be heard as the tab slides over the tongue on the base.
Caution: Mating surfaces of the magnetic core are exposed when the sensor is open. Silicone grease, present on the cores to
!
prevent rust, can capture grit and dirt if care is not exercised. Operation can be impaired if anything prevents good contact
between pole pieces. Visually check the mating parts of the core before closing the current sensor.
Please Read Instructions Carefully Before Installation!
