Installation
Step 1.
Locate an appropriate mounting panel or enclosure near the
protected device.
Step 2.
Drill four mounting holes (see Figure 6 on page 14).
Step 3.
Secure the SEL-2600 using the four bolts and locknuts provided.
Step 4.
Ground the SEL-2600 by connecting Terminal 26 to an
appropriate electrical ground.
Step 5.
Connect as many as 12 RTDs to the SEL-2600 terminal blocks
(see Figure 5 on page 13).
Step 6.
Record the type and location of each RTD in Table 1 on page 4.
Step 7.
Connect a dry contact to the SEL-2600 contact input Terminals 20
and 21 as appropriate.
!
CAUTION:
Do not connect ac or dc voltage to the contact input.
Step 8.
SEL-701 Motor Relay Application
➢
Connect the SEL-2600 to the SEL-701 Motor Relay using a
single fiber-optic cable (SEL part number C801FZ or
C801FD). Follow the SEL-701 setting instructions in
SEL-701 Motor Relay Application on page 4.
SEL-2030 Communications Processor Application
➢
Connect the SEL-2600 to the SEL-2030 Communications
Processor using a single fiber-optic cable and a fiber-optic
transceiver as outlined in SEL-2030 Communications Proces-
sor Applications on page 6.
Step 9.
Connect ac line power to the SEL-2600 through Terminals 23 and
24 (120 Vac) or Terminals 23 and 25 (250 Vac). The green
ENABLE LED illuminates when ac power is applied and the
internal diagnostics are complete.
Step 10.
Verify the SEL-2600 is operating properly.
➢
The green ENABLE LED is illuminated.
➢
The red TX LED pulses twice per second.
➢
The red INPUT LED illuminates when the SEL-2600 contact
input is energized.
➢
The SEL-701 or SEL-2030 receives valid RTD measure-
ments.
