14 mm Interface Terminal

• PLC-R… : equipped with relay

• PLC-B… : base terminal block, unequipped

1. Note on designation and order no.

The PLC-R… interface terminal 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 in-

terface terminal block equipped with relay, PLC-R…, is therefore

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

gable miniature relay REL-MR…

2. Product information for the

Mark

The requirements of the EMC guideline, 89/336/EEC (Electro-

magnetic Compatibility) and the harmonized European stan-

dards listed with this are fulﬁlled by all the articles bearing the

CE mark.

The EC declarations of conformity are kept available for the au-

thorities responsible in acc. with the above-mentioned guideli-

ne, 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 hou-

sings (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).

3. Installation instructions

Caution: Never perform work on the device while

mains voltage is applied! Danger to life!

3.1. Contact protection circuit

In order to achieve

as long an electrical service life as pos-

sible

for the relay and also avoid the coupling of inductive volta-

ge 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 INTERFACE.

3.2. 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 recom-

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

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

tervals of 10 cm!

3.3. Bridging voltage potentials

Identical voltage potentials of adja-

cent terminal blocks (A1, A2, 11…)

can be bridged with plug-in bridges.

The bridges must snap in fully.

To remove the bridges, refer to ﬁg.2.

• 2-position bridges for bridging just a few devices:

FBST 6…

without intermediate separating plate

FBST 8…

• FBST 14…

2-position plug-in bridge to link

adjacent connections of a 14 mm PLC interface

• FBST 500…

max

≤

32 A)

500 mm long plug-in bridges off the

roll for bridging a great number of devices.

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

ded 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 correspondingtermi-

nal points. In the case of higher currents, PLC-ESK GY input

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

3.4. Separating plate PLC-ATP BK

The separating plate (Order No.

29 66 84 1, ﬁg. 3) 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.

Prescored and consecutively numbered break-outs make

continuous bridging possible.
