SWITCHING RELAYS

INSTALLATION INSTRUCTIONS

APPLICATION

The R4222 and R8222 are general purpose relays for use in refrigeration and air conditioning equipment, vending machines, and other applications requiring general purpose switching. R4228 and R8228 are heavy-duty relays with the same application.

A variety of switching configurations are available. Refer to Tables 1 and 2. Contacts are available for Powerpile (millivoltage), pilot duty, and power pole applications. R4222 and R4228 models have line voltage; R8222 and R8228 models have low voltage coils.

INSTALLATION

CAUTION

1Installer must be a trained, experienced service technician.

2Disconnect power supply before beginning installation.

3Always conduct a thorough checkout when installation is complete.

LOCATION

Mount the relay on a flat, solid surface as close as possible to the equipment being controlled. The relay may be mounted in any position except with the terminals pointed down. Secure in place with two screws through holes or slots in the mounting base. See Fig. 1 for mounting dimensions.

WIRING

Disconnect power supply before making wiring connections to prevent possible electric shock and equipment damage.

All wiring must comply with local codes and ordinances. Crimp female quick connects to the system wires and attach to the male quick connect terminals of the relay. The relay has molded terminal numbers and a circuit diagram for easy identification when wiring. Fig. 2 shows the terminal location and circuits of all models.

Do not exceed contact and coil ratings when wiring into the system.

Contact ratings

R4222 and R8222 contacts are available for pilot duty, power pole, or millivoltage applications. R4228 and R8228 contacts have power pole ratings only. See Tables 3 and 4.
