2. Use a grounding wrist strap when installing and
removing circuit boards. A grounded workstation is
also recommended.
3. Handle printed circuit boards only by the edges. Do not
touch components or connector pins.
4. Ensure that all electrical connections are completely made
and none are partial or floating. Ground all equipment to
a good earth ground wiring.

Manually position the housing in the correct direction to
allow for easy wiring. The housing can rotate one full turn.
1. Make sure the power supply is turned off.
2. Unscrew and remove housing cover.
3. Connect power leads to the proper terminals. To simplify
wiring, the terminal strips may be removed from the
module by lifting the front edge of the terminal block.
Refer to Figure 5.
a. 120 VAC – Connect the “hot” wire to terminal marked
L1 and the “neutral” to terminal L2/N. There is no con-
nection to the center terminal.
b. 240 VAC – Connect one wire to terminal L1 and the
other wire to terminal L2/N. There is no connection to
the center terminal.
c. 24 VDC – Connect wires to terminals (+) and (-). There
is no connection to the center terminal.
4. To ensure optimum noise immunity, attach the ground
wire to the green grounding screw inside the housing base.
Caution:
On 24 VDC units, the negative terminal of the power
supply is isolated from ground and proper earth grounding
of the power supply shield wire is necessary for noise
immunity.
5. Connect relay terminals. Refer to Figure 6.
6. Set the fail-safe jumper as described in the table on page 6.
For alarm applications, it is recommended that the
de-energized status of the relay be used as the alarm status.
This allows detection of power failure as an alarm status.
7. Wiring is complete. Replace the housing cover.
8. Apply power to the unit.
