NOTICE: This manual should be left with the owner/user of this

equipment.

General Description

Model PR-2 and PR-3 are epoxy encapsulated single pull double throw
(SPDT) relays that are activated by 10 to 40 VDC. The PR-2 also uses a red
LED as a visible indication of relay coil energization. The PR-3 contains an
additional black and red wire used for redundant power input.

Mounting

For ease of installation, the PR-2/PR-3 relays may be mounted in a vari-
ety of ways. They can be attached within compatible equipment or in
a separate enclosure using a mounting screw. Double sided tape is also
provided for additional support.

Wiring

NOTE: All wiring must conform to applicable local codes, ordinances,

and regulations.

The PR-2/PR-3 connections are shown on the label on the side of the relay.
Using the enclosed wire nuts, secure the electrical connections appropriate
to the application. Provisions must be taken to separate power limited
and non-power limited wiring per National Electrical Code requirements.
Field installable wiring connected to the product must have a minimum
1/4 inch spacing between the power limited and non-power limited wire.
