QUALIFIED PERSONNEL
For the purpose of this quick reference and product labels, a qualified person is one who is
familiar with the installation, construction and operation of the equipment and the hazards
involved. In addition, he has the following qualifications:
Is trained and authorized to energize, de-energize, clear, ground and tag circuits and
equipment in accordance with established safety practices.
Is trained in the proper care and use of protective equipment in accordance with
established safety practices.
Is trained in rendering first aid.
Note
indicates information about the device or respective part of this booklet
which is essential to highlight.
Warning!
Hazardous voltages are present in this electrical equipment during
operation. Non-observance of the safety rules can result in severe
personal injury or property damage.
Only qualified personnel shall work on and around this equipment after
becoming thoroughly familiar with all warnings and safety notices of this
booklet as well as with the applicable safety regulations.
The successful and safe operation of this device is dependent on proper
transport and storage, proper handling, installation, operation, and
maintenance by qualified personnel under observance of all warnings
and hints contained in this booklet.
In particular the general erection and safety regulations (e.g. IEC, EN,
DIN, VDE, or other national and international standards) regarding the
correct use of hoisting gear must be observed. Non-observance can
result in death, personal injury or substantial property damage.

Unpacking and Re-packing
When dispatched from the factory, the equipment is packed in accordance with the
guidelines laid down in IEC 60255-21 which specify the impact resistance of packaging.
This packing shall be removed with care, without force and without the use of inappropriate
tools. The equipment should be visually checked to ensure that there are no external traces
of damage.
Please observe absolutely all notes and hints which may be enclosed in the packaging.
Before initial energization with supply voltage, or after storage, the device shall be situated
in the operating area for at least two hours in order to ensure temperature equalization and
to avoid humidity influences and condensation.
For further transport, the transport packing can be re-used when applied in the same way.
The storage packing of the individual relays is not suited for transport. If alternative packing
is used, this must also provide the same degree of protection against mechanical shock and
vibration as laid down in IEC 60255-21-1 class 2 and IEC 60255-21-2 class 1.
Storage and Transport
The device should be stored in dry and clean rooms. The limit temperature range for storage
of the relays or associated spare parts is -25 °C to +55 °C, corresponding to -13 °F to 131 °F.
The relative humidity must be within limits such that neither condensation nor ice forms.

Installation Hints
Connect the relay solidly with low impedance to the protective earth continuity system of the
switch gear!
Make connections via the screwed or snap-in terminals. Observe labelling of the individual
terminals to ensure correct location; observe the max. permissible conductor cross-sections
and bending radius.
The screw-type terminals can be used without wire end ferrules. Pin-end connectors
generally must not be used.
The use of the screwed terminals is recommended; snap-in connection requires special
tools and must not be used for field wiring unless proper strain relief is ensured.
The terminals of the flush mounting case are 4-pole voltage connector modules.
The terminal screws are tightened at delivery, and must be loosened before inserting any
wire.

Connection data of voltage modules:
Maximum wire cross-section: 1.5 mm2(AWG 15); with or without wire end ferrules
Wire strip length without wire end ferrules: 10 to 12 mm
Sleeves length (wire range) of wire end ferrules: min. 10 mm
(e.g. DIN 46 228-E1,5-10).
After attachment, the wire end ferrules must comply with the geometry for terminal cells
according to EN 60 947-7, class A1.
Select the corresponding wire end ferrules and attachment tools.

2 set squares C73165- A63-C201-1 and 4
distance pieces C73165-A63-C203-1 are nec-
essary for panel surface mounting.
Fix the set squares to the mounting rails of the
device, using 8 standard screws size M4.
Fit threaded holes, sleeves, or bolts size M6
into the panel, according to the above draw-
ing.
Fasten the device with the fixed set squares to
the panel and ensure correct distance by
means of the distance pieces.
When using fixed bolts: Fit the distance pieces
onto the bolts and fasten the device by means
of female screws.

For panel flush mounting, 2 set squares
C73165- A63-C201-1, 4 distance ele-
ments C73165-A63-C203-1 and 8 stand-
ard screws size M4 are necessary since
the mounting rails of the device are not
sufficient for the high weight of the de-
vice.
Fix the set squares to the panel, using 8
standard screws size M6, according to
the drawing.
Mount the device to the set squares us-
ing standard screws size M4.
If the device is mounted in switch-gear
cabinets, the set squares can be omitted
provided the cabinet processes ade-
quate solid mounting rails. If not, use 2
set squares C73165-A63-C200-2 (size
28 SEP = 19 inches)
