6.5. Standard Alarm Connections

See charger inside cover label for original factory alarm relay assignments (see Figure 2). Alarm relay
assignments are custom configurable using the SENS Setup Utility. Alarm circuits are rated 2A at 30V AC
or DC. Connect alarm wiring to the respective terminals on the pluggable terminal block in the charger
(see Figure 4). To make wiring easier, the terminal block unplugs from its header. Pull terminal block
straight out from header to remove. Connect wires to terminal block by tightening screws at each
position. After wires are connected, plug terminal block securely back into header. Wire from FAIL or OK
to COM depending on whether the alarm should be present on an open or closed circuit (see Table 8).
Connect alarm terminals only to low voltage, limited energy ("Class 2") circuits. The terminals accept 28-
16 AWG (0.08-1.5 mm
driver. Route alarm wiring at least ¼ inch (6 mm) away from DC wiring, AC wiring, and the circuit board.
