COIL RATINGS:
All coils meet Underwriters Laboratories Inc. requirements for Class B coils. If coil voltages other than those listed below are desired, contact your local Honeywell representative for additional information.

1. Voltages listed are for the relay base mounted vertical. With the terminals pointing down, pickup voltage is increased by 12 percent.
2. R8222D,G,J,N,R,T,V only.
   NOTE: Pickup voltage varies with pole form. Specific models will have lower tolerance than shown above.

TERMINALS: Quick-connects are provided as shown:

MOUNTING: Use 2 screws (up to No. 10 size) through holes in the metal base. Base is designed for easy  replacement of competitive relays.
AMBIENT TEMPERATURE RANGE: Minus 20 F [minus  29 C] to 155 F [68 CJ.  DIMENSIONS: See Fig. 1. SWITCHING CONFIGURATIONS
The following tables give switching configurations, contact ratings, and terminal designations for the switching relays. For example, the R4222A is a spst switching relay with normally open power rated contacts. The R4222K is a spst relay with normally open contacts rated for pilot duty applications. Electrical connections to the A and K models would be made to terminals 1 and 3.

2. 4074BVJ Receptacle with 8 color-coded plug-in leadwires and retaining bail, for panel mounting ap­plications; see Fig. 2.
3. Q633A1003-4 x 4 plate-mounted relay receptacle with metal relay cover and 8 color-coded plug-in leadwires.
   NOTE:  
   1. Use the receptacle in applications within the current carrying rating of the wire size and quick-connect terminal being used.
   2. The receptacle will accept relays with double quick-connect terminals.
4. 135959 Receptacle only. Leads and quick-connect terminals are not supplied with the receptacle.
   NOTE: Not all standard quick-connect terminals will be adequately retained in this receptacle. It is recommended that a quick-connect terminal with 0.016 inch [0.406 mm] maximum material thickness be used (0.012 inch (0.305 mm] preferred). The maximum permissible dimension between the rolls is 0.115 inch [2.92 mm]. These requirements are met by AMP, Inc. Faston “250” series terminal No. 42100-1 quick­connects or equivalent.
5. 135887 Wire Bail only.

INSTALLATION:

WHEN INSTALLING THIS PRODUCT …

1. Read these instructions carefully. Failure to follow them could damage the product or cause a hazardous condition.
2. Check the ratings given in the instructions and on the product to make sure the product is suitable for your application.
3. Installer must be a trained, experienced service technician.
4. After installation is complete, check out product operation as provided in these instructions.

CAUTION:

Disconnect power supply before beginning in­stallation to prevent electrical shock or equipment damage.

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 or as shown in Fig. 3 or 4. See Fig. 1 for mounting dimensions.

FIG. 3-MOUNTING RELAY ON PANEL WITH SHEAR­ FORMED TAB AND ONE SCREW.

WIRING
Disconnect power supply before connecting wiring to avoid electrical shock or 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 circuit diagram for easy identification when wiring. Fig. 6 shows the location and circuits of all models. Do not exceed contact and coil ratings when wiring into system.

Leadwires are provided with the 135959 Receptacle in 4074BVJ Bag Assembly for additional relay pole positions. Insert the required leadwires in the relay receptacle as follows.
Determine the leadwire colors required for the relay and application desired. Push the leadwire terminal into the receptacle plate from the side stamped with the numbers (Fig. 5). When inserting the leadwire, the tang on the quick-connect terminal must align with the small clearance slot in the terminal opening. Press the terminal in until it locks in place.
