Notes:

(1) Mounting screws and the fastening

bracket are included in the package.

(2) Mount the relay with the proper

mounting direction — i.e. with the

direction of the mark on top of the

relay case matching the direction of the

mark on the terminal block. (The

direction of the terminal block is the

upward direction of the relay.)

This document describes the Panasonic SP Relays and their associated terminal sockets and mounting boards, designed for industrial applications.

Function Description

The Panasonic SP Relays are designed to be used with specific terminal sockets (SP2-SF and SP4-SF) and mounting boards (SP-MA). These components facilitate the secure and organized installation of SP relays in control panels or other electrical enclosures. The terminal sockets provide an interface for wiring the relays, while the mounting boards offer flexible installation options, including direct chassis mounting and DIN rail mounting.

Usage Features

Terminal Socket Mounting

Mounting Direction: Relays must be mounted with the proper orientation. The "M" mark on top of the relay case should align with the "M" mark on the terminal block. The upward direction of the terminal block corresponds to the upward direction of the relay.
Fastening Bracket: Mounting screws and the fastening bracket are included in the package.
- Mounting: Insert part "A" of the fastening bracket into the mounting groove of the terminal block. Then, fit part "B" into the groove by pressing with the tip of a minus screwdriver.
- Removal: Slide part "B" of the fastening bracket from the groove while pressing with a minus screwdriver. While "B" is in this position, press part "C" of the bracket towards the relay side with your finger, and lift it up to the left side to remove it from the groove.

Mounting Board Usage

Relay Compatibility: Both SP relay 2 Form C and 4 Form C can be mounted to the mounting slats of the SP-MA.
Mounting Options:
- Direct Chassis Mounting: Use two M3 screws. Refer to the specification diagram for the mounting pitch.
- DIN Rail Mounting: Use a 35mm (1.378 inch) wide DIN rail (DIN46277).
DIN Rail Mounting Method:
1. Fit the arc-shaped claw of the mounting slat into the DIN rail.
2. Press on the side of the mounting slat as shown in the diagram.
3. Fit the claw part on the opposite side.
Removal from DIN Rail: To remove the relay, press down on the mounting slats so that the claws move outwards, allowing the relay to be detached.

Maintenance Features

Fastening Bracket Removal: The design of the fastening bracket allows for relatively easy removal using a minus screwdriver and finger pressure, facilitating relay replacement or maintenance.
DIN Rail Mounting/Removal: The mounting board's design enables straightforward installation and removal from a DIN rail, which is beneficial for system upgrades or maintenance tasks.
Sliding Prevention: When mounting to a DIN rail, it is recommended to use a commercially available fastening bracket if there is a need to prevent the mounting slat from sliding in the rail direction. This ensures stability and prevents accidental dislodgement during operation or maintenance.
RoHS Compliance: The products are RoHS Directive compatible, indicating adherence to environmental standards for hazardous substances, which can be a factor in long-term maintenance and disposal.
