3.2 Electrical Connection
a. Power Wiring
The GASS-2040 system is intended to be hard wired via a customer supplied disconnect switch
and wire capable of supplying 5A/10A at 115/230/VAC. The external disconnect switch must meet
IEC 60947-1 & 60947-3 stds and must be installed in close proximity to the equipment, within easy
reach of the operator and shall be clearly marked as the disconnecting device for the GS-2040.
Connect the system to an appropriate earth ground. Adhere to all electrical code requirements in
effect at the installation site.
Connect the power wiring as shown in Figure 4 below. The fuse block is supplied with 1.25" x 0.25"
glass fuses and if necessary should be replaced with one of similar rating. A fuse block for PLC
power, located in the upper terminal strip, is supplied with a 5mm x 20mm, 1.0A, fast-blow fuse and
should be re-
placed with one of
similar rating, if necessary.

b. I/O Wiring
The PLC outputs operate at 24 VDC and are “sourcing” (See Figure 5). This means that when
commanded to turn on by the PLC logic, the output terminal goes from 0 VDC to +24 VDC and
supplies current to the device being signaled or powered. The device must pull no more than 0.5A
and must have a minimum load of 10 mA at 24 VDC. A 0 VDC terminal connection is supplied as a
current sink to complete the output circuit.
The PLC inputs operate at 24 VDC and are “sinking” (See Figure 6). This means that the input is to
turn on and signal the PLC logic that an event has occurred or is desired, +24 VDC must be
applied to the input terminal. A +24 VDC terminal is supplied as a current source to complete the
input circuit.
