Honeywell MCSS, MCSP Installation Instructions
MCSS/MCSP Current Switches
INSTALLATION INSTRUCTIONS
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.
CAUTION
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.
WARNING
Risk of electrical shock.
Can cause severe injury, property damage or death.
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.
Never rely on the LED’s of the MCSS-A/MCSP-A to determine whether power is present at the current switch. The Red LED will indicate whether the current is above the adjustable trip point. The Blue LED will indicate that the current is below the adjustable trip point.
The MCSS-A and MCSP-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. Leave a minimum distance of 1” (3 cm) between the current switch and any other magnetic devices such as contactors and transformers.
For applications in which the normal operating current is below the 0.32Amps (MCSS-A) or 0.70Amps (MCSP-A) trip point (See Figure 5 below), the conductor being monitored may be looped through the sensor 6 times giving you a total operating current of 6X the original current. Example: A small fan operating at 0.2A should be wrapped through the sensor 7 times to give you a total operating current of 1.4 Amps flowing through the MCSS-A or MCSP-A.
For applications in which the normal operating current is greater than 150 Amps or for conductor diameters larger than 0.530” (1.35 cm) in diameter, an external 5 Amp Current Transformer (5A CT) must be used as shown in Figure 6 below. Remember that the secondary of the 5A CT must be shorted together before the power may be turned onto the monitored device.
