Flush mounting

There exists two basic possibilities of mounting: mounting of clock into wall niche and mounting into a panel. For both mounting is very important to prepare appropriate holes according to drawing and clock body.

Without back cover

1. For wall niche mounting, drill four anchoring holes into a wall of a diameter adequate to accommodate appropriate screws of 4 to 5 mm diameter. As a template for marking the position of holes the clock body can be used.

2. For panel mounting, drill four anchoring holes of 2.6 mm diameter into a panel to accommodate screws of 4 to 5 mm diameter. As a template for marking the position of holes the clock body can be used.

3. On mains powered clock connect the incoming conductors in accordance with the description on the power supply unit using WAGO or equivalent clamps.

4. Mount the connectors to the cable of the synchronization signal line, the temperature sensor cable, to the keyboard cable, Ethernet or to the RS-485 if these are used.

   Attention

   If the clock is synchronized by LGC variant, please navigate to Clock Operation Non-Network Clock Operation to get detailed info about connection of various synchronization sources and receivers.

5. Push the synchronization line connector, the temperature sensor connector, the keyboard connector, Ethernet connector or the RS-485 jacks into the corresponding terminals on the control PCB.

Warning

Be careful not to swap terminals. Check the markings of the jack‑plugs.

6. Put the clock into prepared hole. Check if any cables is not pinched between the clock body and hole / niche edges.

   

7. Fix the clock by four screws to panel / wall.

   

With back cover

1. The clock consists of clock part and back cover. Dismount 4 screws and remove the cover.

2. For wall niche mounting, drill two anchoring holes into a wall of a diameter adequate to accommodate appropriate screws of 4 to 5 mm diameter. As a template for marking the position of holes the back cover can be used.

3. For panel mounting, drill two anchoring holes of 2.6 mm diameter into the panel to accommodate appropriate screws of 4 to 5 mm diameter. As a template for marking the position of the holes the back cover can be used.

4. Pull incoming conductors through the hole in the back side of the cover and fix the cover to a wall / panel using screws.

   

5. On mains powered clock connect the incoming conductors in accordance with the description on the power supply unit using WAGO or equivalent clamps.

6. Mount connectors to cable of synchronization signal line, temperature sensor cable, Ethernet cable or to RS-485 if these are used.

   Attention

   If the clock is synchronized by LGC variant, please navigate to Clock Operation Non-Network Clock Operation to get detailed info about connection of various synchronization sources and receivers.

   For LGC variant, check and configure the position of DIP switch according to used synchronization signal (applies only for DCF, MOBALine, polarized impulse line or IRIG‑B).

7. Push the synchronization line connector, the temperature sensor connector, the keyboard connector, Ethernet connector or the RS-485 jacks into the corresponding terminals on the control PCB.

Warning

Be careful not to swap terminals. Check the markings of the jack‑plugs.

8. Put the clock into prepared hole. Check if any cables is not pinched between the clock body and back cover.

   

9. Fix the clock by four delivered screws to back cover.
