Storage The unit should be stored in a clean, dry environment. Storage temperature is -40 o C (-40 o F) to +60 o C (+140 o F). Avoid exposing the unit to areas of high condensation. All of the packaging materials should be left intact until the unit is ready for installation.
Equipment Performance For planning purposes, in order to obtain maximum system performance, the SPD must be located as close to the circuit to be protected as possible, minimizing the interconnecting wire length.
**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.
OPERATION and FEATURES SPD's do not require operator intervention after installation. However, the LEDs should be checked weekly to ensure that the SPD is functional. NOTE: The PMH3XLM has a green LED for each phase which extinguish when the module is no longer providing protection (fault condition).
The audible alarm can be silenced by pressing the "Mute Alarm" button on the touchpad, until a qualified electrician or service person is available to service the unit. The red "Service" LED will continue to be illuminated even though the audible alarm has been silenced.
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.
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.
