Optional High Current Relay Connections
Optional high current relay assignments are custom configurable using the SENS Setup Utility. There are
two options of high current alarm relays available from the factory. The first variant of alarm circuits (2) is
rated 5A at 120VAC. The second variant of alarm circuits (2) is rated 3A at 150VDC and 10A at 240VAC.
Connect optional alarm wiring to the respective terminals on the pluggable terminal block in the charger
(see Figure 5 for detail). To make wiring easier, the terminal block unplugs from the 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 9).
The terminals accept 26-12 AWG (0.14-4.0 mm
2
) conductors. Tighten connections to 5.5 Lb-In (0.62 Nm)
using a small slotted driver. Route alarm wiring at least ¼ inch (6 mm) away from DC wiring, AC wiring,
low voltage wiring, and the circuit board.
