Electrical Connections
WARNING
For explosionproof applications, disconnect power before installing, servicing or removing electrical components.
Personal injury or property damage from fire or explosion may result if power is not disconnected.
Select junction boxes, wiring and/or cable glands that are rated for the environment of use (such as hazardous location,
ingress protection, and temperature). Failure to use properly rated electrical hardware wiring and/or cable glands can
result in personal injury or property damage from fire or explosion. Wiring connections must be in accordance with local,
regional, and national codes for any given hazardous area approval. Failure to follow the local, regional, and national codes
could result in personal injury or property damage from fire or explosion.
An electrical 1/2-14 NPT conduit connection with 18 inches of 18 AWG lead wires is located at the bottom of the case.
The conduit connection is integral to the body of the switch.
The action of the controller is such that rising level will cause the Normally Closed (N/C) contacts to close and the
Normally Open (N/O) contacts to open. Falling level causes the opposite action.
Connect L2e electrical wires as shown in table 2. To reverse the action refer to table 2 and reverse wiring for normally
open and normally closed.
