Precautions
3 GENERAL PRECAUTIONS
The G70D is used only for outputs.
If the Output Block is connected to a DC inductive load, connect
a diode to the Output Block to protect against counterelectromotive voltage. This may result in damage to the output
element and a short or open--circuit malfunction.
Electric Shock
It is extremely dangerous to connect or disconnect relays with the
power turned on. Always turn off the power before wiring the
Output Block or replacing the relays.
3 CORRECT USE
Do not connect or disconnect connectors with the power turned
on; faulty operation may occur.
The G70D-SOC16(-1) and G70D-VSOC16 are equipped with
G6D-1A, 24 VDC relays. The G70D-FOM16(-1) and
G70D-VFOM16 are equipped with G3DZ-2R6PL, 24 VDC power
MOSFET solid state relays.
Wiring
Be sure to turn OFF the power when wiring the Output Block and do
not touch the charged terminals of the Output Block, or an electric
shock may result. Turn ON the power after the Output Block is wired
and the relay block is mounted.
Apply specified voltages to the input terminals. Otherwise, the
Output Block may malfunction, be damaged, or burn.
Relay Models
Do not connect the Output Block to any load exceeding the rated
switching voltage or current of the Output Block. Otherwise, faulty
insulation, contact weld, or faulty contact of the Relays, damage
to the Relays may result or the Relays may malfunction or burn.
The life of a Relay 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 Output Block in places with flammable gas. A fire
or explosion may result from the heat of the Relays or a spark
from the Relays when they are switched.
Power MOSFET Models
Do not connect the Output Block to loads consuming a total
current exceeding the rated output current of the Output Block.
You may damage the output element and a short or open--circuit
malfunction may result.

Replacing Relays
Turn OFF the Output Block to replace Relays. Otherwise, an
electric shock may result or the Output Block may malfunction.
Mount the Relay by pressing the upper part straight down until
the Relay is locked with the hooks. Make sure none of the Relay
terminals are bent or the Output Block may malfunction or radiate
heat.
Wiring
Make sure that the polarity of each terminal is correct, the power
lines are wired properly, and the terminal voltage is appropriate.
Do not disconnect or connect the connector while the Output
Block is turned ON. Otherwise, the Output Block may
malfunction.
Cable Connector Locks
Before the Output Block is turned ON, make sure that the
connectors of all the cables connected to the Output Block are
locked.

Installation Environment
Do not install the Output Block in the following locations or
damage or malfunction may result.
-
Locations with direct sunlight.
-
Locations with ambient temperature ranges not within --25°C
to 55°C (--13°F to 131°F).
Terminal block
-
Locations with rapid temperature changes resulting in
condensation or relative humidity exceeding 45% to 85%.
Expansion
terminal block
-
Locations with corrosive or inflammable gas.
-
Locations with excessive dust, salinity, or metal powder.
-
Locations with vibration or shock affecting the Output Block.
-
Locations with water, oil, or chemical sprayed on the Output
Block.

Screw Tightening Torque
Removing and Mounting the Terminal Block and
Relay Block
Tighten all screws of the Output Block properly, or the Output
Block may malfunction.
Refer to the diagram below.
1. Removing
-
Terminal screws: Tighten each terminal screw to a torque of
0.78 to 1.18 N : m.
Check that the load and the Output Block are both turned OFF.
-
Mounting screws: Tighten each mounting screw to a torque
of 0.59 to 0.98 N : m
Turn the mounting screws of the relay block counterclockwise
alternately and equally until the relay block is slightly raised.
-
Relay block mounting screws: Tighten each mounting screw
to a torque of 0.59 to 0.98 N : m.
When the relay block is slightly raised, disconnect the protruding
part A of the relay block from the interior wall of the Output Block.
Cleaning
Do not use paint thinner to clean the surface because damage or
discoloration may result.
Further turn the mounting screws counterclockwise and remove
the mounting screws. Then remove the relay block.
2. Mounting
Handling
Check that the load and the Output Block are both turned OFF.
Do not drop the Output Block or shock or vibrate the Output
Block excessively. This may damage the Output Block and result
in malfunction.
Check that the part B of he terminal block is free of metal dust or
other foreign materials.
Disassembling, Repairing, and Modifying
Mount the relay block straight along the groove of the terminal
block.
Do not disassemble, repair, or modify the Output Block. An
electric shock may result or the Output Block may malfunction.
Press the both ends of the relay block and place the protruding
part A onto the interior wall of the Output Block.

G70D-VSOC/G70D-VFOM
Terminal block
For ease-of-use and space-saving, the G70D-VSOC16
incorporates a terminal block and relay block that can be
separated from the Output Block. The relay block has operation
indicators and replaceable Relays along with electrical check
terminals for monitoring the operation of the Output Block.
The Expansion Terminal Block can be mounted to the Output
Block for power line connections.

Nameplate of Terminal Block
Electrical Check Terminals
As shown in Figure 1, the nameplate of the terminal block is
located on the bottom surface of the relay block.
The terminal block of the G70D-VSOC16 in operation is located
under the relay block. Therefore, unlike the terminal blocks of
other models, electrical checks on the terminals are not possible
with multimeter probes. The relay block of the G70D-VSOC16,
however, incorporates electrical check terminals, each of which is
connected to the corresponding terminal of the terminal block. All
the pairs of these terminals share single terminal numbers
respectively.
To fill in the nameplate, remove the nameplate from the relay
block. Then return it to the original location when finished.
To read the nameplate after the Output Block is mounted to a
panel, for example, pull out the nameplate from the bottom
surface of the relay block as shown in Figure 2.
To check these terminals, apply multimeter probes to these
terminals.
Do not touch these energized terminals with a thin metal object
or similar objects. Doing so may result in an electric shock.

Mounting the Expansion Terminal Block
Insert the hooks of the Expansion Terminal Block into the
mounting holes on the terminal block and slide the Expansion
Terminal Block so that it will not separate from the terminal block.
Tighten the mounting screw of the Expansion Terminal Block
securely.
