[. . . ] Rather they are used to send a signal or operate the coil of another, higher amperage device which does the actual switching of power. Dual knockouts, in the sizes of ½, ¾ and 1 inch, are provided for cable routing and conduit connections. Mount the ALM to a flat, vertical surface, such as a wall. Tools Required screwdrivers (Phillips and flat blade) drill and assorted bits wire strippers wood screws (#10) anchors (if required) WARNING: BEFORE MAKING ANY CONNECTIONS TO THE LOAD OR INVERTER, ENSURE THAT ALL AC AND DC POWER IS DISCONNECTED FROM THE INVERTER AND THE ALM. Pre-Installation Before installing the ALM, read all instructions and cautionary markings located in this manual. NOTE: Check for existing electrical, plumbing, or other potential areas of accidental damage prior to making cuts in structural surfaces.

Terminal Block Wiring · Lift the appropriate lever for the relay contact. · Insert the wire (stripped back 1/4 inch) into the terminal block. Please refer to the auxiliary relay section of the inverter's operation manual for additional information. NOTE: Due to the various ways the ALM can be wired, detailed wiring instructions can not be given in this manual. Please refer to the operation section of this manual for wiring suggestions. CAUTION: Do not wire the relays directly to a highamperage device. Connection to a high-current device will open the fuse in the common line and possibly damage the relay.
