13.2.3 Mounting the MP-3000 Drawout Relay
1. Remove the Drawout Inner Chassis from the outer case.
2. Place the outer case flush against the backside of the panel
so that the case studs project through their respective holes.
Figure 13.2 shows the panel mounting diagram.
3. The plastic outer flange is seated on the front of the panel.
It is attached to the top, center, and bottom studs that pro-
trude through the panel with the #10-32 hex nuts and lock
washers included with the relay.
NOTE: Use only the supplied narrow-profile nuts. Standard-width
10-32 hex nuts interfere with the insertion of the inner chassis.
4. The relay inner chassis can now be inserted into the case
and checked for proper seating into the latching mechanism.
13.2.4 Mounting the URTD Module
There are no provisions for mounting the URTD module on the MP-
3000 Drawout Case. The URTD module must be mounted remotely
from the MP-3000 Drawout Case.
The URTD module has both an electrical and fiber optic communica-
tion interface to the MP-3000 relay. The electrical connections are
made through the terminal blocks. The fiber optic cable is run through
the opening in the back of the outer case and connected directly to the
inner chassis before it is fully inserted. Refer to Subsection 13.3.1.
13.2.5 Mounting the PONI Communications Module
The MP-3000 Drawout Relay must be ordered with the communica-
tions module as it is integral to the inner chassis construction and
wired through the terminal connectors.
The communications address is set via switches accessible on the
inner chassis.

The following material supplements the information in Subsection 6.1.
Figures 13.3 through 13.7 show the typical connection and wiring
diagrams for the MP-3000 Drawout. Note the following:
1. Direct wire connections to the terminal blocks must be sizes
#14 AWG to #10 AWG (2.5 mm
priate sized spade and ring lugs should also be used to
accommodate the wires.
2. In each terminal block, wire the lower tier terminals before
the upper tier terminals.
3. All contacts are shown in the de-energized position.

NOTE: Each output relay may be configured for mode 1 or mode
2 operation. In mode 2, the relay is energized when control
power is applied to the MP-3000. For mode 2 operation, the
contacts are normally in the opposite state from that shown.
Refer to Subsection 13.4.
4. The INCOM communications LED can be seen through a
hole in the outer case on the left side.
NOTE: All wiring must conform to applicable federal, state, and local
codes.
13.3.1 fiber Optic Installation
The URTD fiber optic cable connects directly to the inner chassis. The
installation procedure is as follows:
1. Remove the relay inner chassis from the outer case assem-
bly.
2. Route the fiber optic cable through the grommeted hole in
the back of the outer case. See Figure 13.3.
3. The fiber should be long enough to extend 2 to 3 in. (50.8 to
76.2 mm) out of the front of the case.
4. Carefully hold the fiber to the left inner side of the case and
insert the relay inner chassis half-way into the case.
5. Connect the fiber cable to the fiber optic connector on the
relay inner chassis. The fiber plug on the cable has a latch-
ing mechanism that locks the fiber cable into the fiber outlet.
6. Carefully push the relay inner chassis the rest of the way
into the case until the quick-release latches engage.
NOTE: Be careful not to kink or bend the fiber cable when inserting
the relay inner chassis.
13.3.2 fiber Cable Disconnection
To remove the relay inner chassis from the case when the fiber cable
is used, perform the following procedure:
1. Unlatch the inner chassis from the case and remove it half-
way out.
2. Disconnect the fiber cable by squeezing the connector latch
and gently pull the fiber plug from the fiber socket.
NOTE: Failure to disconnect the fiber cable from the relay inner
chassis may result in damage to the fiber and, possibly, to the
fiber socket.
3. Continue to remove the relay inner chassis.

13.4 application Considerations

13.4.1 Mode 1 and Mode 2 Output Contacts
The outputs of the MP-3000 relay can be configured in either mode 1
or mode 2 operation. Refer to Subsections 5.12.1 and 6.2.3 for more
information on the functionality of modes 1 and 2.
