2 INSTALLATION
The 269Plus is available in a drawout case option. The operation of the relay is the same as described else-
where in this manual except for the differences noted in this section. The physical dimensions of the drawout
relay are as shown in Figure 2–16: DRAWOUT RELAY PHYSICAL DIMENSIONS on page 2–26. The relay
should be mounted as shown in Figure 2–17: DRAWOUT RELAY MOUNTING on page 2–27.
The 269Plus drawout relay can be removed from service without causing motor shut-down. This can be useful
for replacing, calibrating, or testing units.
• RELAY MOUNTING: Make cutout as shown and drill six 7/32" holes on mounting panel. Approximately
2½" should be clear at the top and bottom of the cutout in the panel for the hinged door. Ensure that the
five #6-32 nuts are removed from the threaded studs in the mounting flange and that the drawout chassis
has been removed from the drawout case. Install the case from the rear of the mounting panel by aligning
the five #6-32 threaded case studs to the previously drilled holes. With the studs protruding through the
holes secure the case on the right hand side with two #6-32 nuts provided. Install the hinged door on the
front of the mounting panel using three #6-32 nuts provided.
• FIELD ADJUSTMENTS: There are four screws holding the plastic 269Plus case to the drawout cradle.
These screw into holes which are slotted to compensate for panel thickness. If the 269Plus case is
mounted at the extreme end of the slot intended for thin panels, the relay will not seat properly and the
door will not shut over the relay when installed on a thick panel. Loosening the screws and moving the
relay forward before retightening will fix the problem.
• RELAY REMOVAL: Open the hinged door. Next remove the two ten finger connecting plugs making sure
the top one is removed first. Swivel the cradle-to-case hinged levers at each end of the 269Plus cradle
assembly and slide the assembly out of the case.
• RELAY INSTALLATION: Slide the 269Plus cradle assembly completely into the case. Swivel the hinged
levers in to lock the cradle assembly into the drawout case. Install the two ten finger connecting plugs mak-
ing sure the bottom plug is installed first. Close the hinged door and secure with the captive screw.
There must be at least ½" clearance on the hinged side of the drawout relay to allow the door to
open. Once correct control power is applied to the relay, a clicking sound will be heard approximately
every second. This normal operation indicates that the relay is scanning through the RTDs regard-
NOTE
less if RTDs are in use.
IMPORTANT: When removing the drawout relay cradle assembly the top ten finger connecting
plug must be withdrawn first. This isolates the 269Plus output relay contacts before power is
removed from the relay. When installing the drawout relay cradle assembly the bottom ten fin-
NOTE
ger connecting plug must be installed first. This causes power to be applied to the 269Plus
relay before the output relay contacts are placed in the circuit.
• After a 269Plus relay cradle assembly has been removed from the drawout case it is recommended that
the hinged door be closed in order to reduce the risk of electric shock.
Due to the hardware configuration of the drawout relay shorting bars, the
page 5) should not be changed without consulting the factory. Spare shorting bars are included with each dra-
wout specifically for the required modification. Wiring for the 269Plus drawout is shown in Figure 2–18: DRA-
WOUT RELAY TYPICAL WIRING DIAGRAM on page 2–28. If it is required that any of the output relay
configurations in Figure 2–18: DRAWOUT RELAY TYPICAL WIRING DIAGRAM be different than shown, this
information must be stated when the relay is ordered.
The 269Plus Drawout does not meet the requirements of IEC947-1 and IEC1010-1.
No special ventilation requirements need to be observed during the installation of this unit.
