Figure 2: Mounting R683 Module Inside a NEMA 3R Type Enclosure

Software: Requires RLM module driver.

Fault Detection: Hardware watchdog timer.

Temperature Range: -20-150 °F (-28.9 to 65.6 °C),

non-condensing.

Battery: 7-year lithium battery provides 10,000 hours

(minimum) of data retention during power outages.

A/D Input Resolution: 10 bit.

Listed By: PAZX (UL 916).

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

Verify that the module is addressed correctly.

Turn the R683's power switch OFF. (This prevents

the module from being powered up until proper

voltage is verified.)

Terminate AC power at the wiring source (usually a

circuit breaker or other AC source).

Terminate power to the transformer.
