■
Selection of a power supply
● To protect the system against erroneous voltage from the power supply line, use an insulated
power supply with an internal protective circuit (power supply with reinforced insulation or
double insulation).
● The regulator on the unit is a non-insulated type.
● Select a power supply larger than the capacity of the units to be connected. In the minimum
configuration, select a power supply of 24 W or larger.
■
Power supply voltage
● Confirm that the voltage of the power supply to be connected is within the allowable range.
Rated input voltage Allowable voltage range Rated output capacity
24 V DC 20.4 to 28.8 V DC 24 W or more
■
Power supply cable
● Use the power supply cable (Part No.:AFPG805) that comes with the unit to connect the
power supply.
Brown: 24 V DC, Blue: 0 V, Green: Function earth
● Also, twist the power supply cables to minimize adverse effects from noise.
5.1.3 Grounding
■
Use dedicated grounding
● The grounding connection should have a resistance of 100 Ω or less.
● The point of grounding should be as close to the GM1 as possible. The ground wire should
be as short as possible.
● Sharing the ground with another device may have an adverse effect. Therefore, be sure that
grounding is dedicated.
