2. Product information for the

c Mark

The requirements of the EMC guideline, 89/336/EEC

(Electromagnetic Compatibility) and the harmonized

European standards listed with this are fulfilled by all the

articles bearing the CE mark.

The EC declarations of conformity are kept available for the

authorities responsible in acc. with the above-mentioned

guideline, article 10. Address, see above.

When operating relay modules, the operator must see that

the requirements pertaining to emitted interference for

electrical and electronic operating equipment (EN 50081)

are observed on the contact side and must perform any

necessary measures.

Relay modules with IP 20 protection or less must be

installed in rooms for electrical operating apparatus or in

enclosed housings (e.g. switch cabinets).

When working on the switch cabinets, the operating

personnel must first discharge electrostatic current before

opening switch boxes or switch cabinets and before

touching the modules (to protect the modules against

electrostatic discharge).

mains voltage is applied! Danger to life!

3.1. Contact protection circuit

In order to achieve as long an electrical service life as

possible for the relay and also avoid the coupling of

inductive voltage in other components/system parts, a

contact protection circuit (e.g. damping diode, varistor,

RC element etc.) should be provided on the consumer in

the case of a high load and particularly in the case of a

share of inductive load. Detailed information is to be found

in the PHOENIX CONTACT catalog part 6 (INTERFACE I).

3.2. Modules with spring cage connection

Push the screwdriver (blade: 0.6 x 3.5 mm; in

acc. with ISO 2380-1) at an angle of approx.

45 ° in the direction of the arrow into the

aperture (see fig. 2). The spring cage opens

and the stripped conductor end can be

inserted at an angle

from above into the

conductor connec-

tion cone. When the

screwdriver is

removed, the

conductor is

automatically

clamped.

3.3. Fixing on the mounting rail

An end bracket must be positioned at the start and end of

every terminal strip. Wherever it is subject to vibration, we

recommend E/UK1 (Order No. 12 01 41 3).

When subject to vibration, the mounting rail must be fixed at

intervals of 10 cm.

3.4. Bridging voltage potentials

Identical voltage potentials of adja-

cent terminals (A1, A2, 13, BB) are

bridged using plug-in bridges. The

bridges must snap in completely.

To remove the bridges, see fig.3.

• FBST 6… 2-pos. plug-in bridges

max

≤ 6 A)

• 500 mm long FBST 500.. continuous plug-in bridges (I

max

≤ 32 A).

The bridges can be cut to length using EKS1, the single-

handed cable cutter (Order No. 12 01 83 7). Minimum length

that can be cut is 30 mm.

Currents ≤ 6A can be fed directly into the corresponding

terminal points.

In the case of higher currents, PLC-ESK GY input terminal

blocks (Order No. 29 66 50 8) are to be used.

3.5. Separating plate PLC-ATP BK

The separating plate (Order No. 29

66 84 1, fig. 4) must be inserted in

the following cases

always at the beginning and

end of each PLC terminal strip

for voltages greater than 250 V

between identical terminals of

adjacent modules (L1,L2,L3)

for reliable isolation between

adjacent modules

to isolate adjacent bridges of different potentials

• for visual separation of functional groups

Continuous bridging is made possible by the perforated

break-out points.

1. Note on designation and order no.

PLC-R…, an interface terminal block equipped with a relay,

consists of:

a) PLC-B…, the unequipped base terminal block, and

b) REL-MR…, the pluggable miniature relay (see fig.1).

The designation and order no. printed on the packaging of the

interface terminal block equipped with relay, PLC-R…, is

therefore not identical to that on base terminal block PLC-B…

and pluggable miniature relay REL-MR…

• Identical potentials of adjacent connections (A2, 13, BB)

are bridged with FBST plug-in bridges.

Feeding the PLC ground on the input side into "A2", and

voltage source on the output side into "13" and "BB" is

only necessary once.

• No extra external output terminal block is required for the

load return line. It is connected to terminal point "BB".

4.4. PLC-R…SEN sensor series for input signals

Example: N/O contact (fig. 7)

• Identical potentials of adjacent connections (A2, 13, BB)

are bridged with FBST plug-in bridges.

Feeding the PLC supply on the output side into "13" and

the switch/initiator supply on the input side into "A2" and

"BB" is only necessary once.

• No extra external terminal block is required for supplying

the switches. It is connected to terminal point "BB".
