Preparing the RLY-800 Knockouts
Perform the following steps to use the additional
knockouts for the RLY-800:
1. Determine which knockout(s) are to be used.
The RLY-800 contains five knockouts for power
wiring and an external antenna connection:
•
Knockouts A, B and D – Enters the Class 1
wiring compartment. The knockouts A and D
are for 1/2 inch conduit or cord grips. A 1/2
inch cord grip is supplied with the RLY-800.
Knockout B is for 3/4 inch conduit or cord grip
(not supplied).
•
Knockout C and E – Enters the Class 2 wiring
compartment. (Class 1, if the divider is not
present). Knockout E is used for the factory-
installed external antenna connector.
2. Select the knockout to be used for wiring the
RLY-800 based on how and where the device will
be mounted in the field.
3. Remove the knockout prior to mounting by
using a drill and a conduit-style step drill bit.
The dimple in the center of the knockout allows
you to accurately position the step-drill bit in
the center of the knockout for a clean hole.
The knockout may also be removed by inserting a
screwdriver into the knockout slot at several
points and prying it out. Do not hit the knockout
directly, as this may damage the case.
For added flexibility, the RLY-800 enclosure
allows side-entry access holes, D and E, to be
used for accessing the wiring compartment.
A 3/4 inch threaded nipple accessory or cord grip
is required to use knockout B.
4. Insert the supplied cord grip into the open
knockout and secure it with the cord grip nut.
You are now ready to attach the RLY-800 to the
mounting bracket as described in
RLY-800 to the Universal Bracket” on page 8
