Unpacking and Preliminary Inspection • Inspect the entire shipping container for damage or signs of mishandling before unpacking the unit. • Remove the cardboard packing and further inspect the unit for any obvious shipping damages. • If damage found is a result of shipping or handling, immediately file a claim with the shipping company and forward a copy to APC. Storage o o o o The unit should be stored in a clean, dry environment. Storage temperature is -40 C (-40 F) to +60 C (+140 F).

Service Clearance In addition to national and local code requirements, 36 inches of service clearance is needed at the front of the SPD. Equipment Performance To obtain the maximum system performance, the unit must be located as close to the circuit to be protected as possible, minimizing the interconnecting wire length. For every foot of wire length, approximately one (1) nanosecond of turn-on/ turn-off time will be added, and approximately 175 volts (6kV/3kA, 8/20 microsecond) will be added t

Wiring Size & Installation Torque With a parallel connection, the size of the wiring to the SPD is independent of the ampere rating of the circuit to be protected. The recommended wire size is based on the unit’s transient surge current capabilities. #6 AWG is the recommended wire size for phase, neutral and ground conductors. Disconnect Switch The PM Series is designed for connection to a 30A to 60A breaker. The PM3 and PM4 Series SPDs can be equipped with an optional internal disconnect switc

PM SERIES INSTALLATION INSTRUCTIONS (Typical Unit - Three Phase WYE, 4 Wire, plus Ground) This section provides basic installation instructions for the PM Series SPD. Per UL 1449 Paragraph 1.4, SPD’s “are intended for installation on the load side of the main overcurrent protection”. Locate the SPD as close as possible to the circuit to be protected to minimize the wire length. This will optimize SPD performance. Note that these instruction are not intended to supercede local or national code

Operation and Features SPD’s do not require a great deal of operator intervention after installation. NOTE: The PM Series has a green LED for each phase which extinguishes when the module is no longer providing protec- tion (fault condition). All of the PM Series of SPDs contain a diagnostic circuit which monitors the suppressor status continuously and automati- cally. If a fault condition were to occur, the built-in front panel audible alarm will sound and a red “Service” LED will light, indica

Surge Counter Option In units so equipped, the surge counter option provides a means to total the number of transient voltage surges encountered since the counter was last reset. The surge counter circuitry includes a “supercap”. This will provide power up to four days to retain memory should a power outage occur. NOTE: There is a 10 - 15 minute charging cycle once power is connected, before the surge counter operates. The surge counter registers the sum of L-N and L-G transient surges. There ar
