4.1 AC Line Connection
Connect the AC Line to terminals L1 (Line Fuse) and L2, as shown in Figure 2-2. If one of the AC line
inputs is a neutral (N), connect it to terminal L2.
Note:
This control operates on 115 or 208/230 Volt AC line input and is factory set for 208/230 Volt AC
line input (Voltage Select Switch is factory set to the “230” position). See Section 6.
4.2 Ground Connection
Connect all ground wires (earth), of connections to the control, to the green ground screw on the
chassis, as shown in Figure 2-2.
4.3 AC Line and Armature Fusing
The AC Line fuse is factory installed. The Armature fuse (supplied separately) must be installed in the
armature fuse holder, as shown in Figure 2-3. Select the correct fuses, as shown in Table 4-2.
Fuses are available from your distributor. All fuses should be normal blow ceramic 3AG, MDA, or
equivalent. On domestic 230 Volt AC lines, separate branch circuit protection for each line must be
used.
