Mounting
The R683 module's design allows it to be mounted two
ways. The R683 can be mounted inside a NEMA 3R type
rainproof enclosure or it can be mounted directly to the
backplate of a conventional control panel.
NEMA 3R Mounting:
The R683 module is constructed with metal mounting
flanges that allow the module to be mounted inside a
NEMA 3R type enclosure.
There are two large holes and two small holes in both
ends of the metal mounting flanges. The two small holes
are used to mount the module to the enclosure. The two
large holes allow screws to pass through the module and
hold the enclosure to the surface on which it is mounted
(see Figure 2).
Panel Mounting:
To mount the R683 module directly to a surface, the
NEMA 3R flanges must be removed. These flanges are
designed to be broken off along the perforation. After
removal, mount the module directly to the desired
surface.
Power Wiring
CAUTION: The R683 module is a Class 2 device (less
than 30 VAC). Take appropriate isolation measures
when mounting the R683 module in a control panel
where Class 1 devices (120 VAC) or wiring are present.
NOTE: Whenever possible, terminate and verify power
and communication to all modules before terminating
any inputs and outputs.
Procedure
1.
Verify that the module is addressed correctly.
2.
Turn the R683's power switch OFF. (This prevents
the module from being powered up until proper
voltage is verified.)
3.
Terminate AC power at the wiring source (usually a
circuit breaker or other AC source).
4.
Terminate power to the transformer.
