**On 4-Wire Power Systems, neutral to ground bonding should be installed per national and local electrical codes. Failure to comply may result in damage to the equipment.** ELECTRICAL CONNECTIONS Overcurrent Protection The Surge Protection Device (SPD) draws very little current under normal conditions and will only conduct for a brief duration upon encountering a transient surge voltage. APC SPDs contain internal fusing to protect against abnormal voltage conditions. Note: Fuses are not replace

Dry Contacts The PMH3XLM includes a set of Dry Contacts available at a terminal block at the right-front of the inside panel. This feature provides two sets of normally open (NO) and normally closed (NC) contacts which can be used for remote monitoring of the PMH3XLM’s operating status by changing state when there is an alarm condition. Examples of remote monitoring equipment include a computer interface board, emergency management system, or APC’s Environmental Monitoring Unit Option (see Envi

CORRECTIVE MAINTENANCE (Repair) SurgeArrest PMH3XLM units are designed for years of reliable, trouble-free operation. However, even the most reliable equipment can fail. Built-in diagnostics are an integral part of the PMH3XLM and indicate if service is required. Audible alarms and abnormal illumination of LEDs indicate problems within the PMH3XLM, and possibly within the electrical system. Quality SPDs, such as the PMH3XLM, are designed and tested to withstand severe duty. However, various elec

PREVENTIVE MAINTENANCE - Inspection and Cleaning Inspection of the SPD should be performed periodically to maintain reliable system performance and continued transient voltage surge protection. While it is difficult to establish a preventive maintenance schedule because conditions vary from location to location, inspections for failed LEDs and other signs of trouble utilizing the built-in diagnostics should be performed on a routine basis (weekly or monthly).
