Backplane 125840-02 (3500/15 rear card) BENLTY module

Description

3500/15 125840-02 The following recommendations are offered, but applicable safety codes for your area or equipment

type should also be consulted. The baseplate’s metal back must be grounded using a separate

conductor; the baseplate mounting screws are not considered to be an acceptable ground

connection by themselves. Use a minimum AWG #12 (3.3 mm2) wire with a ring terminal and star

lock washer under the head of one of the baseplate’s 3500/15 125840-02 two lower mounting holes. These two holes

have openings to the side to allow connecting a wire and ring terminal under the head of a

mounting screw. Connect the other end of this ground wire to a tapped hole in the panel that the

baseplate is mounted to, using a machine screw, 3500/15 125840-02 star lock washer, and flat washer. Alternately, if

your panel has a ground stud, it is recommended you use a nut and star lock washer for each wire

on the ground stud to ensure adequate grounding. Where connections are made to a painted panel,

the paint should be removed so clean, bare metal is exposed at the connection point. Terminals and

hardware used should be compatible with the aluminum baseplate material.

3500/15 125840-02 All baseplates grouped together in a Series 90-30 PLC system must have a common ground

connection. This is especially important for baseplates that are not mounted in the same control

cabinet.

3500/15 125840-02 Grounding 19” Rack-Mounted Baseplates

There are two Adapter Brackets choices for mounting a 10-slot Series 90-30 baseplate to a 19”

Rack. Regardless of which of the two Adapter Brackets is used, the 19” Rack should be

grounded as per the instructions in “System Grounding Procedures” section. (For details on the

Adapter Brackets, 3500/15 125840-02 see the “Mounting a Baseplate to a 19” Rack” section earlier in this chapter.)

Nineteen-Inch rack-mounted PLC baseplates should be grounded according to the guidelines in

the “Baseplate Safety Grounding” section, using a separate ground wire from the PLC baseplate

as shown in the previous figure.

If using the Recessed Mount Adapter Bracket (IC693ACC313), the ground wire can be

installed as shown in Figure 2-11 with the ground attached to the Recessed Mount Adapter

Bracket. An additional ground wire connecting the Adapter Bracket to a solid chassis

ground on the 19” Rack should be installed. Use the same or equivalent hardware and

paint removal scheme as shown in the previous figure.

If using the Surface Mount Adapter Bracket (IC693ACC308), the ground wire should be

run from the baseplate as shown in Figure 2-11, to a solid chassis ground on the 19” Rack.

Use the same or equivalent hardware and paint removal scheme as shown in the previous

figure.

Programmer Grounding

For proper operation, a computer (programmer) running PLC software must have a ground

connection in common with the applicable baseplate when connecting to a CPU or intelligent

module such as a PCM or DSM. Normally, this common ground connection is provided by

ensuring that the programmer’s power cord is connected to the same power source (with the

same ground reference point) as the baseplate. If the programmer ground is at a different

potential than the PLC ground, a shock hazard could exist. Also, damage to the ports or

converter (if used) could occur when the programmer serial cable is connected between the two.

If it is not possible to ensure this common ground scheme, use a port isolator (IC690ACC903)

between the programmer and PLC serial port connection, and avoid touching the programmer

and PLC at the same time.
