Note
: Line voltage is either 115 VAC, 60 Hz or 220 VAC, 50 Hz. The unit can be powered by line
voltage or optionally by 24 V (DC or AC).
Note
: Each of the signals associated with the control signal terminal block are
not
polarity dependent
(24VAC/DC S.B., LL, PULSE, and O.K.).
Note
: Avoid daisy-chain connections of the control signal returns – if the ground potentials of each
return differ.
1. Set the power switch SW1 located just below the transformer, for line power (115 VAC or
220 VAC) or 24 V DC/AC according to your requirements. See Figure 5.
2. Route the power cable through a cable strain relief on the left side of the connection box
3. Connect the green ground wire to a chassis screw or bolt, preferably using a ring terminal. See
Figure 4.
4. Route the control cable through the right cable strain relief (Figure 4).
5. Connect control cable according to Table 1.
