IMPORTANT
• Use only flexible conduit with the SV2 Series valve NEMA 4/IP66 enclosures
• Wiring must comply with all applicable electrical codes, ordinances and regulations.
• Wiring must comply with NEC Class 1 (line voltage) wiring.
• Use lead wire which can withstand 90°C (194°F) ambient temperatures.
• Voltage and frequency of the power supply connected to this control must agree with those marked on the device.
• Loads connected to the VPS (valve proving sequence) Switch and/or POC (proof of closure) contacts, if used, must not
exceed the ratings given in
• Separate line and low voltage to avoid signal interference. If using conduit, run line voltage and low voltage wiring in
separate conduit.
