Introduction
Validity of documentation
This documentation is valid for the product PNOZ msi b4 Box from Version 2.0 .
This operating manual explains the function and operation, describes the installation and
provides guidelines on how to connect the product.
Description
The shielded junction box PNOZ msi b4 Box is used to connect
}An incremental encoder with an additional feed for the incremental encoder supply
or
}An incremental encoder in conjunction with a proximity switch with/without pull resistor
(dual encoder evaluation) with an additional supply for the proximity switch
or
}2 proximity switches with/without pull resistor with an additional supply for the proximity
switches
to the Pilz speed monitors.

Installation
}The junction box should be installed in a control cabinet with a protection type of at
least IP54.
}Fit the junction box to a horizontal mounting rail.
}Use the locking slide on the rear of the junction box to attach it to a mounting rail.
}In environments exposed to heavy vibration, the unit should be secured using a fixing
element (e.g. retaining bracket or end angle).
}Open the locking slide before lifting the unit from the mounting rail.
Mounting distances
For the wiring to be EMC-compliant, the junction box must maintain a distance of at least
5.5 mm from other conductive parts (e.g. adjacent housing parts) (see diagram).

Connection
INFORMATION
The connected supply voltages and the sensors have to be supplied from
power supplies that comply with the regulations for extra low voltages with
safe electrical isolation.
Shielded line
Acorn nut
Sealing ring
Connecting piece
Braided shield
Lamellar insert
1. Remove the external insulation of the line and expose the braided shield, depending on
the conductor cross section, to approx. 10-15 mm.
2. Push acorn nut and lamellar insert with gasket onto the line.
3. Bend braided shield to the outside at a right angle (90°).
4. Crimp over braided shield towards the external cable insulation, i.e. crimp it over again
by 180°.
5. Insert connecting piece up to the braided shield and turn it shortly back and forth round
the line axis.
6. Push lamellar insert with gasket into the connecting piece and snap in the anti-twist pro-
tection.
7. Screw the acorn nut firmly.

Internal view
The cable ducts and the corresponding terminals are each labelled identically (X1 ... X4).
}Cable ducts at X1 and X4:
Size M12x1.5 with terminals for cable diameters from 3 to 6.5 mm, tighten with spanner
size SW 14 mm and torque setting 8 Nm.
}Cable ducts at X2 and X3:
Size M16x1.5 with terminals for cable diameters from 5 to 9 mm, tighten with spanner
size SW 17 mm and torque setting 8 Nm.
The identically named signals (GND, S, 24 V...) are connected to each other between the
terminals X1 ... X4 internally.
INFORMATION
When using crimp connectors the connection wires can be inserted into the
connectors of the spring-loaded terminals. Pressing the operating pushbut-
ton is necessary only to undo the connection.
