Dangerous voltages can occur on the connectors, even though the
auxiliary voltage has been disconnected
National and local electrical safety regulations must always be
followed
The device contains components which are sensitive to electrostatic
discharge. Unnecessary touching of electronic components must
therefore be avoided
The frame of the device has to be carefully earthed
Only a competent electrician is allowed to carry out the electrical
installation
Non-observance can result in death, personal injury or substantial
property damage
Breaking the sealing tape on the upper handle of the device will result
in loss of warranty and proper operation will no longer be guaranteed
When the plug-in unit has been detached from the case, do not touch
the inside of the case. The relay case internals may contain high
voltage potential and touching these may cause personal injury.

Relay products, although of robust construction, require careful handling prior to
installation on site. Examine the delivered productsto ensure that they have notbeen
damaged during transport.
If a product has been damaged, a claim should be made to the transport contractor
and the local representative of ABB should be promptly notified.

Compare the order number of the relay with the ordering information to verify that
you have received the right product. The order number is found on a label under the
lower handle of the relay:
)LJ &KHFNLQJWKHRUGHUQXPEHURIWKHUHOD\

The relay products contain components that are sensitive to electrostatic discharge.
The electronic circuits arewell protected bythe enclosureand therefore unnecessary
removals of the plug-in unit and the Human-Machine Interface (HMI) must be
avoided.

The packing material of cardboard is 100% recyclable.
Warning!
When checking the order number of the relay plug-in unit, be
careful not to lift the handle beyond 25°(approx. 40 mm). Lifting
the handle any further will detach the plug-in unit from the case.

REM 610 can be flush mounted, semi-flush mounted, mounted in a rack or wall
mounted. You will need separate mounting kits for the different methods except for
the flush-mounting method.
The relay’s construction with a detachable plug-in unit allows an easy installation.
Before mounting the relay, the plug-in unit has to be detached from the relay case.
'HWDFKLQJDQGLQVWDOOLQJWKHSOXJLQXQLW
Prior to detaching the plug-in unit from the case, the auxiliary voltage must be
disconnected.To detachtheplug-inunit,liftthelowerhandleuntilthe spring-loaded
locks on both sides of the handle are released and the unit is pushed about 6 mm out
of the case. This will separate the connectors and you can easily pull the unit out of
the case.
The relay features an automatic short-circuit mechanism in the current transformer
(CT) connector. Therefore, detaching the plug-in unit will not open the secondary
circuit of the CT which otherwise could cause dangerously high voltages.
Signal connectors will be left open when the plug-in unit is detached.

Before fitting a relay plug-in unit into a relay case, check that the unit and the case
have the same order number. The order number of the case is printed on the bottom
plate inside the case. However, if a substitute plug-in unit has to be used instead of
the original unit, ensure that at least the first ten characters in the order numbers of
the case and the plug-in unit are identical, as in the following example:
In order to obtain the identical functionality to that of the original product, all
charactersinthe ordernumber,exceptforthoseindicatinga sparepart,shouldmatch
the ones of the case.
Order number of the relay case 5(0$+CMP
Order number of the plug-in unit 5(0$+CNR

The relay features a built-in mechanical coding system that helps to prevent
dangerous situations from arising, should a non-suitable plug-in unit be fitted into a
relay case.
To install a plug-in unit into a case, first check that the lower handle is down in its
initial position and then push the unit into the case until the locks click; see the figure
below:

Danger!
Forcing a non-suitable plug-in unit into a case will break the relay
and may cause dangerous situations.

You will not need a separate mounting kit when flush mounting the case. All
mounting accessories are included in the case.
To flush mount the case to the cut-out in the panel, first loosen the 4 M5 fixing
screws approximately 7 turns. Mount the case to the mounting cut-out and tighten
the screws; see Fig. 4.3.-1. The allowed value range for the fixing screws’tightening
torque is 0.7...1Nm.
The enclosure class of the flush-mounted device is IP 54 on the front side, while the
rear side fulfils the IP 20 requirements (top of the relay: IP 40).

The semi-flush mounting kit (1MRS050696) includes a raising frame, a gasket and
screws and is needed for the semi-flush mounting of a case. The gasket is used when
an IP 54 degree of protection (according to the IEC 60529) is required for the front
side. If the gasket is not used, an IP 50 degree of protection is obtained.
Mount the raising frame to the cut-out in the panel with four screws according to Fig.
4.4.-1.

The case can be mounted in a 19" rack using one of two different mounting panels.
The type of mounting panel required depends on the number of cases mounted.
When mounting only one relay, use mounting kit number 1MRS050694. When
mounting two relays next to each other, use mounting kit number 1MRS050695.

Kit 1MRS050697 is used for mounting the case on a wall, i.e. projection mounting,
and contains two two-piece mounting brackets (frame and rail parts), a backplate
andscrews.The mountingbracketsare madeof prepainted(light-grey,Pantone420)
steel sheet. The kit also includes detailed mounting instructions and dimensions for
screw holes.
A wall-mounted case can be pulled out 160 mm and turned 45 (or 90) degrees
downwards(or upwards) when the wires are to beconnected. Part “A”locks the case
toselected(pushed-inorpulled-out)position,see figuresbelow.Thecase isreleased
by pushing the locks. By loosening the knurled-head screw “B”, the case can be
rotated, see Fig. 4.6.-2.

Connection terminals are described in the Technical Reference Manual. Each
contact has its own identification number, X2.1, for instance. The numbering of the
contacts runs from top to bottom, except the connectors X2.1 and X5.5 which are
numbered from bottom to top; see Fig. 5.1.-1.
Terminal blocks of screw-compression and ring-lug type are used for electrical
connections while transceivers of snap-in type are used for plastic fibre-optic
connections. If terminals of screw-compression type are used:
1. Open the screw terminal before inserting a wire into it for the first time. To open
the screw terminal, turn the fixing screw anticlockwise until the terminal hole is
wide open (the inside of the terminal hole is surrounded by metal).
2. Insert the wire and turn the fixing screw clockwise until the wire is firmly fixed.
Only use screwdriver and insert bits for Phillips (PH 1) cross-recessed head screws
(M3.5) when handling CT terminals (X2.1) of screw-compression type.
)LJ 6FUHZGULYHUDQGLQVHUWELWVIRU&7WHUPLQDOVRIVFUHZFRPSUHVVLRQW\SH
It is also possible to use terminals of ring-lug type for the CTs. If using terminals of
ring-lug type:
1. Open the lid that covers the ring-lug fixing screw (every fixing screw has its
own lid) with the tip of a screwdriver.
2. Screw off the screw, slide it through the terminal lug and screw it back on.
3. Close the lid.
When the wires for the CTs have been connected, install the snap ferrite ring,
provided with the relay, around the wires as close to the relay terminals as possible.
(OHFWULFDOFRQQHFWLRQV
All connections are made on the rear of the case. No soldering is needed.
Each signal connector (X3.1 and X4.1) terminal is dimensioned for one 0.2...2.5
mm2 wire or two 0.2...1.0 mm2wires.
Connect the wires from the CTs to the right device according to the phase order and
the coupling scheme. Each terminal for CTs is dimensioned for one 0.5...6.0 mm2
wire or for two maximum 2.5 mm2wires.
A separate earth lead of at least 2.5 mm2has to be connected from the protective
earth screw between connectors X4.1 and X3.1 (upper screw; see Fig. 5.1.-1) to the
earth bar.

When using RTD sensors or thermistors, use a double shielded cable. Connect the
cable shields to the chassis earth screw between connectors X4.1 and X3.1 (lower
screw; see Fig. 5.1.-1).
Terminals on the optional RS-485 communication module are dimensioned for one
0.08...1.5 mm2wire or for two maximum 0.75 mm2wires.
