2 Assembly
The connection to the 110/230 V AC power network can only be done by authorized personnel
with appropriate qualification and training.
Danger of electric shock when dismounting the cover with warning triangle.
2.1 Wall mounting single-sided stainless steel clock
The clock consists of two parts. Visible front stainless steel panel with display and
back stainless steel body with connecting terminal block. Both parts of the clock
are screwed by four allen screws. These screws are placed on the front panel.
Unscrew the allen screws and remove the front panel from the clock body.
Disconnect the interconnecting cables by decoupling the terminals on the control
PCB.
Drill three anchoring holes into the wall, of a diameter adequate to accommodate
wood-type screws of 4 to 5 mm diameter. As a template for marking the position of
the holes the anchoring clock body can be used.
Pull the incoming conductors through the hole in the clock body and fix the clock
body to the wall.
Connect the incoming conductors in accordance with the descriptive sheet placed
next to the connecting terminal block (chapter 2.5). Give the conductors an
appropriate shape or cut them off to a length that will not obstruct the placement of
the front part of the clock into the clock body.
Mount the connectors to the cable of the temperature sensor, to the keyboard
cable, Ethernet or to the RS 232 and RS 485 interface cables, if these have been
delivered.
Push the temperature sensor connector, the keyboard connector, Ethernet
connector or the RS 232 and RS 485 jacks into the corresponding terminals on the
control PCB (chapter 2.6 and 2.9). Check the marking of the jack-plugs, in order to
prevent their mix-up.
Connect the interconnecting cables into the corresponding terminals on the clock
control PCB.
Put the front panel into the clock body. Check if any cable is not pinched between
the back side of front panel and the clock body.
Fix the front panel to the clock body by the four allen screws.
2.2 Ceiling and side mounting double-sided stainless steel clock
The double-sided clock consists of three parts, one front panel serving as the
control module (this one encompasses the jacks to connect powering voltage,
synchronisation source, the temperature sensor and the keyboard to the clock),
and the second front panel serving as the display module (with the terminal for the
connection of the interconnecting cable).Third part is stainless steel clock body
with connecting terminal block. Both front panels are interconnected via a 10-core
flat cable. Both front panels are screwed into stainless steel clock body by four
allen screws for each side. The clock suspension part is delivered separately.
Pull the incoming conductors through the pipe which serves as the clock
suspension. Secure the ceiling suspension (or the side console) to the ceiling
(or the wall), using 4 wood screws of 5 mm diameter.
Unscrew the allen screws from both front panels.

Disconnect the interconnecting cables by decoupling the terminals on the control
PCB.
Remove both front panels from the clock body.
Pull the incoming conductors through the pipe insert in the clock body. Slip-on the
clock body onto the suspension in a way that the screws fit into the lower groove
on the pipe insert. Fix the connection by tightening the screw using an Allen key.
Connect the conductors to the terminal block on the clock body, in accordance with
the descriptive nameplate (chapter 2.5). Give an appropriate shape to the
conductors or cut them off at a length which does not obstruct the mounting of the
clock into the clock body.
Mount the connectors to the cable of the temperature sensor, to the keyboard
cable, Ethernet cable or the RS 232 and RS 485 interface connectors, if these
have been delivered.
Put the control front panel to the clock body and screw it by four allen screws. Care
should be taken when placing the cables between the clock body edge and the
back side of the control front panel, so as not to nip them. Connect the 10-core
interconnecting cable to the anchoring connector.
Push the temperature sensor connector, the keyboard connector, Ethernet
connector or the RS 232 and RS 485 jacks into the corresponding terminals on the
control PCB (chapter 2.6). Check the marking of the jack-plugs, in order to prevent
their mix-up.
Connect the 10-core interconnecting cable into the corresponding plug on the
clock control PCB of the display front panel.
Put the display front panel into the clock body and screw it by four allen screws.
Care should be taken when placing the cables between the clock body edge and
the back side of the display front panel, so as not to nip them.
2.3 Ceiling and side mounting single-sided stainless steel clock
The single-sided clock consists of two parts, one front panel and stainless steel
clock body with connecting terminal block. The front panel is screwed into clock
body by four allen screws. The clock suspension part is delivered separately.
Pull the incoming conductors through the pipe which serves as the clock
suspension. Secure the ceiling suspension (or the side console) to the ceiling (or
the wall), using 4 wood screws of 5 mm diameter.
Unscrew the allen screws from front panel.
Disconnect the interconnecting cables by decoupling the terminals on the control
PCB.
Remove front panel from the clock body.
Pull the incoming conductors through the pipe insert in the clock body. Slip-on the
clock body onto the suspension in a way that the screws fit into the lower groove
on the pipe insert. Fix the connection by tightening the screw using an allen key.
Connect the conductors to the terminal block on the clock body, in accordance with
the descriptive nameplate (chapter 2.5). Give an appropriate shape to the
conductors or cut them off at a length which does not obstruct the mounting of the
clock into the clock body.
Mount the connectors to the cable of the temperature sensor, to the keyboard
cable, Ethernet cable or the RS 232 and RS 485 interface connectors, if these
have been delivered.
Push the temperature sensor connector, the keyboard connector, Ethernet
connector or the RS 232 and RS 485 jacks into the corresponding terminals on the

© MOBATIME 8 / 16 800945.01
control PCB (chapter 2.6). Check the marking of the jack-plugs, in order to prevent
their mix-up.
Put the front panel into the clock body and screw it by four allen screws. Care
should be taken when placing the cables between the clock body edge and the
back side of the display front panel, so as not to nip them.
2.4 Flush mounting single-sided stainless steel clock
There exist two basic possibilities of mounting. Mounting of clocks into the wall and
mounting of the clocks into the panel. For both mountings is very important to
prepare the apropriate holes according to drawings and the clock body.
The clock consists of two parts. Visible front stainless steel panel with display and
back stainless steel clock body with connecting terminal block. Both parts of the
clock are screwed by four allen screws. These screws are placed on the front
panel.
Unscrew the allen screws and remove the front panel from the clock body.
Disconnect the interconnecting cables by decoupling the terminals on the control
PCB.
Insert the clock body into prepared hole in the wall or in the panel.
For wall mounting drill three anchoring holes into the wall, of a diameter adequate
to accommodate wood-type screws of 4 to 5 mm diameter. As a template for
marking the position of the holes the anchoring clock body can be used.
For panel mounting drill four anchoring holes (diameter 2,6mm) into the panel, of a
diameter adequate to accommodate wood-type screws of 4 mm diameter. As a
template for marking the position of the holes the anchoring clock body can be
used.
Pull the incoming conductors through the hole in the back side of the clock body
and fix the clock body into the wall or into panel.
Connect the incoming conductors in accordance with the descriptive sheet placed
next to the connecting terminal block (chapter 2.5). Give the conductors an
appropriate shape or cut them off to a length that will not obstruct the placement of
the front part of the clock into the clock body.
Mount the connectors to the cable of the temperature sensor, to the keyboard
cable, Ethernet or to the RS 232 and RS 485 interface cables, if these have been
delivered.
Push the temperature sensor connector, the keyboard connector, Ethernet
connector or the RS 232 and RS 485 jacks into the corresponding terminals on the
control PCB (chapter 2.6 and 2.9). Check the marking of the jack-plugs, in order to
prevent their mix-up.
Connect the interconnecting cables into the corresponding terminals on the clock
control PCB.
Put the front panel into the clock body. Check if any cable is not pinched between
the back side of front panel and the clock body.
Fix the front panel to the clock body by the four allen screws.
