electrical wiring and conduit in accordance with local electrical codes. The switch is rated as

follows:

The switch is rated as follows:

30 VDC or 125 VAC 1 Ampere Resistive.

The switch should be wired such that if a leak condition is detected, the pump will be shut

down. The switch is the SPDT (single pole, double throw) type and can therefore be connected

to either open or to close upon detection of diaphragm leak condition. Contacts or wires are

identified as follows:

Normally Open (NO) wire color WHITE

Normally Closed (NC) wire color RED

Common (Com) wire color BLACK

THE ENCLOSURE IS LABELED WITH APPLICABLE SAFETY AGENCY RATINGS FOR

HAZARDOUS AREA INSTALLATION

. SINCE THE SWITCH IS OF THE MECHANICAL

CONTACT TYPE, IT CAN NEVER QUALIFY AS NON-SPARKING (NON-INCENDIVE, OR “M”)

FOR OCCASIONAL AND SHORT-TERM HAZARDOUS AREA USE. PROTECTION MUST BE

PROVIDED BY THE ENCLOSURE.
