MINI ADJUSTABLE STATUS
SWITCH SERIES
Installation & Operation Instructions
A/MCS-A, A/MSCS-A
PRECAUTIONS
• This product is not intended to be used for
Life or Safety applications.
• This product is not intended for use in any
hazardous or classi ed locations.
HIGH VOLTAGE
• 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.
GENERAL INFORMATION
The Miniature Adjustable Current switches are
designed for use in any AC current monitoring
application in which you are looking for an adjustable
current switch to monitor normal operating conditions,
equipment failure or preventative maintenance
scheduling for a particular piece of equipment. The
adjustable current switches should be installed on the
line side of the power to the motor, pump, compressor
or other equipment. The adjustable current status
switches can also be used to determine the run time of
your equipment where you want to know when your
piece of equipment runs and for how long it runs when
logging the contact closures on your building
management system or PLC.
MOUNTING INSTRUCTIONS
Make sure that all installations are in compliance with
all national and local electrical codes. Only quali ed
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-A and A/MSCS-A 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
(see Figure 2 (p.2)). Leave a minimum distance of 1" (3 cm) between the current switch and any other magnetic
devices such as contactors and transformers.

Page 2: Wiring Instructions
WIRING INSTRUCTIONS 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-A and A/MSCS-A current switches and the Building Management System or controller. - Page 3 Example: For currents up to 600 Amps (and not below 70 Amps (A/MCS-A) or 95 Amps (A/MSCS-A), where Current Transformer (C.T.) secondary falls below 1 Amp use a 600:5 ratio C.T. as shown in Figure 4.
