Ordering Information
■List of Models
Note: 1. For replacement relays, use relays with the same voltage specifications as the relays provided with the Terminal when it was purchased.
Longer operating life can be achieved by replacing the G6B-4@@ND with the G6B-1147P-FD-US.
2. Standard models are also available without relays mounted to the sockets. To obtain such terminals, replace the “G6B” portion of the
model number with “P6BF.” For example, to order G6B-4BND with empty sockets, use model number P6BF-4BND. Also specify voltage
specifications for models with operation indicators.

Precautions
Wiring
Be sure to turn OFF the power when wiring the Unit and do not touch
the charged terminals of the Unit. Otherwise, an electric shock may
result.
Do not apply overvoltage to the input terminals. Otherwise, the Unit
may malfunction or burn.
Relay Models
Do not connect the Unit to loads exceeding the rated switching power
(switching voltage or current). Otherwise, faulty insulation, contact
weld, or faulty contact of Relays, or damage to Relays may result, or
the Relays may malfunction or burn.
The life of Relays varies with the switching condition. Test the Relays
under the actual operating conditions before using the Relays within
the permissible switching frequency. The use of deteriorated Relays
may result in the faulty insulation of the Relays or cause the Relays
to burn.
Do not use the Unit in locations with inflammable gas. Otherwise, a
fire or explosion due to the heat of the Relays or sparks from the
Relays may result when they are switched.
■Correct Use
Mounting
Heat generated by the relays must be considered when gang-mount-
ing. Space must be provided between the relays or other methods
must be taken to maintain the relays’ ambient temperature at 55 °C
or lower.
Replacement of Relays
G6B-4@@ND
Use the P6B-Y1 Removal Tool as shown in the following diagram.
Be sure to turn OFF the power to the Unit before replacing a Relay.
Relays must be inserted straight onto the socket connector pins to
ensure proper connection.
G6B-48BND models (high reliability) are connected directly to
boards to increase reliability and the relays are thus not replaceable.
If relay replacement is necessary, use the P6BF-4BND Terminal
Sockets together with the G6B-1184P Mini Relays. P6BF-4BND Ter-
minal Sockets are equipped with relay replacement sockets.
Do not mount Relays that are different to one another in voltage.

Replacement is not possible for G6B-48BND.
Wiring
Be sure to connect the input terminals with the correct polarity.
Coil Voltage
Be sure not to impose voltage exceeding the permissible voltage on
the coil continuously.
Do not use the relays when other inductive loads are connected in
parallel with the coil input or when there are surges during power
supply because the built-in diodes used to absorb surge may be
destroyed.
Do Not Use the Following Circuit
Handling
Do not drop, shock, or vibrate the Unit excessively. Otherwise, dam-
age to the Unit may result or the Unit may malfunction.
Make sure that all the Relays are properly mounted before use.
Screw Tightening Torque
Tighten each terminal screw to a torque of 0.78 to 1.18N·m.
Tighten each mounting screw to a torque of 0.59 to 0.98 N·m.
Installation Environment
Do not install the Unit in the following locations. Otherwise, damage
to the Unit may result or the Unit may malfunction.
Locations with direct sunlight.
Locations with an ambient temperature range not within 0°C to 55°C.
Locations with rapid temperature changes resulting in condensation
or locations with relative humidity ranges not within 10% to 90%.
Locations with corrosive or inflammable gas.
Locations with excessive dust, salinity, or metal powder.
Locations with vibration or shock affecting the Unit.
Locations with water, oil, or chemical sprayed on the Unit.
Disassembly, Repair, and Modification
Do not disassemble, repair, or modify the Unit. Otherwise, an electric
shock may result or the Unit may malfunction.
