Mount this product inside a suitable ﬁre and electrical enclosure. WIRING EXAMPLE For CE compliance, conductor shall be insulated according to IEC 61010‑1:2010. The product design provides for basic insulation only. 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 the center window when it is installed and that will keep the device at least ½” (13 mm) from any uninsulated conductors. Determine cable routing for the controller connection, allowing wiring to reach the mounting location. 2. Drill holes to mount the bracket to the chosen surface using the included screws. 4. Route the conductor through the sensor’s center window and slip the assembly into the mounting bracket. 5. Secure enclosure and reconnect power.

INSTALLATION GUIDE H800 TM PRODUCT OVERVIEW TROUBLESHOOTING The H800 is a current-sensitive switching device that monitors current (amperage) in the conductor passing through it. A change in amperage in the monitored conducter that crosses the switch threshold will cause the resistance of the status output to change state, similar to the action of a mechanical switch. The threshold is fixed at 0.2 A or less. The status output is suitable for connection to building controllers or other appropriate data acquisition equipment operating at up to 30 volts. The H800 requires no external power supply to generate its output. Problem No Reading at Controller Solution • Check for control voltage at sensor (<30 V) • Check for amperage in monitored conductor (>0.25 A) NOTES For load currents greater than sensor maximum rating: 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. > 200 A (Sensor max.) 240AA 250 300A:5A 4AA 4.2 H68xx-5A CT DANGER: 5A CTs can present hazardous voltages. Install CTs in accordance with manufacturer's instructions. Terminate the CT secondary before applying current. CAUTION RISK OF EQUIPMENT DAMAGE • Derate the product’s maximum current for the number of turns through the sensing window using the following formula. Rated Max. Amps ÷ Number of Turns = Max. monitored Amps e.g. : 100A ÷ 4 Turns = 25 Amps max. in monitored conductor • Failure to follow these instructions can result in overheating and permanent equipment damage. For load currents less than sensor minimum rating: Wrap the monitored conductor through the center window and around the sensor body to produce multiple turns. This increases the current measured by the transducer. Program the controller to account for the extra turns, e.g., if four turns pass through the sensor (as shown), then divide the normal controller reading by 4. < 0.25 A (Sensor Min.)
