How to close the zone expander module
1.
To close the zone expander module, put
the housing cover onto the mount with
PCB while ensuring that the insertion
post (element 3 in figure above) on the
lower side of the housing cover fits into
the designated opening for the insertion
post (element 4 in figure above) on the
mount with PCB. Do not force the inser-
tion post into any of the other openings.
2.
Secure the housing cover with the hous-
ing cover fastening screw.
3.
Put the adhesive seal onto the housing
cover fastening screw.
Connection
!
Caution!
Incorrect cabling
Incorrect cabling leads to malfunction
of the system.
!
Caution!
Cable length
Exceeding the permitted cable length is
not covered by CE declarations and
leads to malfunction of the system.
–
Do not exceed the total cable length of
500m
for the primary cables, the control
cables and the contact cables of EM 55,
KD55/1, NKK, NNK 100 2-wire, NVK and IC
400.
Permitted cable length of the primary cables
(PL)
–
Maximum length of one unshielded cable:
3m
–
Maximum length of all shielded cables: 500m
LSN connection
–
Voltage supply can be fed-through (other-
wise free terminals for 0V/+U).
–
Incoming and outgoing LSN can be swapped
over.
4-wire and 2-wire connections
Notice!
A mixed operation of a 4-wire connec-
tion at one of the primary outputs and
a 2-wire connection at the other
primary output is not permitted.
Notice!
For a 4-wire connection always use un-
shielded cables.
For a 2-wire connection always use
shielded cables.
4-wire connection (unshielded)
–
Use a 4-wire connection with an unshielded
cable with a maximum length of 3 m and the
internal EOL resistor (e.g. for magnetic con-
tacts).
–
With an unshielded cable, do
not
connect
contacts with metallic enclosure.
