See NFPA 70E in the USA, or applicable local codes. This equipment must only be installed and serviced by qualiﬁed electrical personnel. Read, understand and follow the instructions before installing this product. Turn oﬀ all power supplying equipment before working on or inside the equipment. Use a properly rated voltage sensing device to conﬁrm power is oﬀ. DO NOT DEPEND ON THIS PRODUCT FOR VOLTAGE INDICATION • Only install this product on insulated conductors. Failure to follow these instructions will result in death or serious injury. INSTALLATION Disconnect and lock out power to the enclosure containing the conductor to be monitored. 1. Locate a mounting surface for the removable mounting bracket that will allow the monitored conductor to pass through center window when it is installed and that will keep the product at least 1/2” from any uninsulated conductors. Determine cable routing for the controller connection, allowing wiring to reach the mounting location.

INSTALLATION GUIDE H10F TM OPERATION CALIBRATION The H10F is a over-current and under-current monitor intended for use with a PLC or other system controller. The current switch learns the nominal amperage on the line, then monitors for amperage changes greater than ±20% of the learned value. If the amperage goes out of the normal range, the current switch changes output state, raising an alarm in the system controller. This alarm state persists until the amperage comes back to within ±15% of the learned value for 30 seconds to ensure that the system has truly returned to normal operation. The status output is suitable for connection to system controllers or other data acquisition equipment operating at up to 1A and 30VDC. The H10F requires no external power supply to generate its output. Establish normal load conditions. NOTES A First Time Power Up: No calibration needed, unit will automatically learn normal load when powered. >5 s To manually learn normal load: >100A (sensor max.) READY! >30 s WAIT STOP Use a 5 Amp (H68xx series) Current Transformer (CT) as shown. This technique can be combined with wrapping (see below) to add range for a low current load on a high current source. LED starts blinking alternating red & green RED GREEN For load currents greater than sensor maximum rating: 240A OK! OK! When only the GREEN LED blinks, the unit is measuring normal current. To reset automatic learn mode (normal load conditions): >5 s RED GREEN LED starts blinking alternating red & green Turn off power while lights are still blinking! At next power-up, unit will automatically learn normal load. 300A:5A OPERATING STATES ES 23 USTRI 972 56 4-85 gon IS IND d, Ore 0-35 VER tlan Por keye Haw 1-80 ® 4A Mode H68xx-5A CT DANGER: 5A CTs can present hazardous voltages.
