Time Switch 4 Channel REG 372 5WG1 372-5AR01
Siemens AG REG 372, 4 pages Technical Manual
Product and Applications Description
The time switch REG 372 is a DIN-rail mounted
device laterally attached to the bus coupling unit
REG 110 (to be ordered separately, order number:
5WG1 110-5AR01). During this it occupies 4 address-
ing locations of the bus coupling unit. Via the four
channels time controlled applications such as illumina-
tion, heating or shutters can be switched on or off. It
can be used as daily, weekly or yearly clock controller.
By connecting an aerial FA and a power unit NT DCF77
the clock controller itself automatically sets the up-to-
date daytime and date (MEZ).
With a reading button the set switching times, date
referenced inputs and 1x-switching commands can be
trialled.
The bus coupling unit REG 110, the power unit
NT DCF77 and the radio aerial FA are not contained in
the volume of delivery and must be ordered separately

Installation Instructions
• The device may be used for permanent interior
installations in dry locations within high voltage
distribution board or small casings.
VWARNING
• The device may be built into distribution boards
(230/400V) together only with appropriate VDE-
devices and must be mounted and commissioned by
an authorised electrician.
• Free DIN rail areas must be covered with covers,
order no. 5WG1 192-8AA01.
• The prevailing safety rules must be heeded.
• The device must not be opened. A device suspected
faulty should be returned to the local Siemens office.

Mounting and Wiring
General description
The N-system DIN-rail device can be installed to N-
system distribution boards, surface or flush mounted, or
to any available DIN-rail EN 50022-35 x 7,5.
During this the electric connection between the clock
controller and the bus coupling unit is established via
the lateral physical external interface (PEI).
The bus coupling unit is not contained in the volume of
delivery and must be ordered separately.
Mounting DIN-rail devices (Figure 2)
- Slide the device (B1) onto the DIN-rail (B2) and
- swivel back the device until the slide clicks into place
audibly.
- Remove the protection film of the adhesive tape (B4),
slip the device to the right and connect it with the bus
coupling unit (B3)

plug-in connection to the bus terminal unit (C2) is ex-
posed,
- press down the slide (C4) with a screw-driver and,
click it into place by a slight pressure and
- swivel the device (C1) from the DIN-rail (C3).
