PNOZ msi b4 Box
Description
The shielded junction box PNOZ msi b4 Box is used to connect
} An incremental encoder with an additional feed for the encoder supply
or
} An incremental encoder in conjunction with a proximity switch (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 monitor.

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 unit to attach the junction box 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.
} Tighten the cable feeds with an SW 16 mm spanner.

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).

If crimp connections are used, the connection wires can simply be plugged
into the spring terminal's plug connection. It's only necessary to press the
actuator button to undo the connection.

EMC-compliant wiring
EMC-compliant wiring for connecting a rotary encoder:
Speed Monitor
To avoid EMC interference we recommend that the shield on the encoder cables or the
housing of the shielded junction box is only connected to earth at a single point:
A or B or C or D or E
Conductor loops outside the shield must be avoided.
EMC-compliant wiring for connecting 2 proximity switches:
