Wiring
A. Wiring and conduit recommendations.
• Use only flexible conduit on NEMA 4/IP66 enclosures.
• Wiring must comply with all applicable electrical codes, ordinances and regulations.
• All line voltage wiring must be NEC Class 1.
• Use lead wire, which can withstand 90°C (194°F) ambient temperatures.
• Power supply voltage and frequency must agree with those marked on the device.
• Load connected to the device must not exceed the ratings given in this document.
• Separate line and low voltage wiring to avoid signal interference. If using conduit, run line voltage and
low voltage wiring in separate conduit.
B. Remove valve front electrical enclosure cover
C. Estimate wiring:
• Observe unique line voltage, limits & interlock wiring required for the SV2 Series valves.
• More wires may be required than typical valves.
D. String wires:
• String wires through conduit, NEMA 4/IP66 enclosure entry points, cord grips and
nuts before wiring to connectors.
• String wires through NEMA 1 / IP20 enclosure rear opening or bottom slot before
wiring to connectors.
E. Connect wires:
• Observe terminal labeling and proper electrical connector placement.
• Connect wires to the wire connectors.
• Plug electrical connectors into their proper sockets.
• Pressure Module must be field connected in electrical enclosure.
F. In connecting more than 1 valve to HMI / PC Tool or a building automation network, be sure to setup
bias + termination resistors.
G. Install plugs and nuts in unused NEMA 4/IP66 electronic enclosure wire entry locations.
• Low voltage, M16 x 1.5
• Line voltage, 1/2 in. NPT
