 Safety
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
switches will not require external power, since the power for the current switch is induced from the conductor being monitored.
The A/MCS and A/MSCS Current Switches should be used on Insulated Conductors Only! The current switch may be mounted
in any position using the (2) #8 x 3/4" Tek screws and the mounting holes in the base. Leave a minimum distance of
1" (3 cm) between the current switch and any other magnetic devices such as contactors and transformers.
#8 x 3/4" Tek Screw
(Qty. 2/Unit)
For applications in which the normal operating current is below the 0.20 Amps (A/MCS) or 0.55 Amps (A/MSCS)
trip point (See Figure 3 below), the conductor being monitored may be looped through the sensor 4 times giving you a total
operating current of 4X the original current. Example: A small fan operating at 0.2A should be wrapped through the sensor
4 times to give you a total operating current of 0.8Amps flowing through the A/MCS or A/MSCS.

  • Page 1 The A/MCS and A/MSCS Current Switches should be used on Insulated Conductors Only! The current switch may be mounted in any position using the (2) #8 x 3/4” Tek screws and the mounting holes in the base. Leave a minimum distance of 1”...
  • Page 2: Operating Specifications

     Wiring ACI recommends the use of a two conductor 16 to 22 AWG shielded cable or twisted pair copper wire only for all current switch applications. A maximum wire length of less than 30 meters (98.4 feet) should be used between the A/MCS and A/MSCS current switches and the Building Management System or controller.
  • Page 3: Troubleshooting

    Verify that the current flowing in the conductor being monitored is above the fixed trip point as listed in the operating specifications. If the sensor is monitoring less than the fixed trip point See Figure 3 on Page ACI Model # Resistance if switch open Resistance if switch closed...
