2-10 Installation
1.
Locate the power supply input terminal block on the back wall at the top left of the
enclosure, as shown in Figure 2-5.
2.
Determine how you will bring wiring from your 115 or 230 Vac power source to the
enclosure. For 115 Vac, you need three wires—high (black), neutral (white) and ground
(green). For 230 Vac, wires are black and red, with green or green-yellow for ground.
3.
Run the power wires to the enclosure through flexible, liquid-tight conduit. Because WPC
2000 is rated NEMA 12 (protected against dust and oil), you must use conduit of the same
rating and make proper connections to ensure NEMA 12 protection.
4.
Connect the ground wire to the set screw terminal on the roof of the enclosure, referring to
Figure 2-5 and to Figure 16 (Herion DSV), Figure 17 (Ross Serpar DSV), or Figure 22
(Ross DM2 DSV) at the back of the manual.
5.
Connect the power wires.
For 115 Vac power, connect the black wire to the LINE terminal and the white wire to
NEUT.
For 230 Vac, connect the black wire to the LINE terminal and the red wire to NEUT.
Strip the wire 1/4 in. from the end. Loosen the screw in the input power terminal block,
insert the stripped portion of the wire, and tighten the screw.
6.
Double-check connections.
7.
Make all necessary conduit connections to ensure NEMA 12 protection.
