Wiring diagram
The wiring diagram is on the
inside of the housing cover.
Connecting to mains power supply 100 - 240 VAC
The mains supply must be connected via a two-pole separator and be adequately protected
against unauthorised interruption.
The mains supply 100 - 240 VAC
may only be connected to the fol-
lowing terminals:
Terminals L, N (supply module)
Terminals 110, 115 (relay module 2x240
VAC)
The device must be protected by a 10 AT external fuse.
The device is fully isolated and requires no grounding connections.
Connection to other terminals is extremely dangerous and can permanently dam-
age the instrument!
Connecting to low voltage supply 24 VDC

CALEC®energy master installation and operating instructions 11
Connecting signal cables
1. Pierce sealing membrane with en-
closed awl
2. Insert
cable
3. Attach cable to terminal screws
according to wiring diagram on the
inside cover
4. Affix strain relief clamp
Closing housing 1. Insert the cover into the hinge from
above and turn to close
2. Tighten the two fixing screws
3. Engage the security sealing caps
with the smooth side on the out-
side.
Once the caps ehave been fitted,
any unauthorised opening of the de-
vice can be detected.
Removing the caps:
Insert a pointed tool and lever out.
The cap is damaged as a result and
must be replaced.

8 Electrical connections
8.1 Connection instructions
Devices with 100 - 240 VAC connections must have a safety fuse with a max. 10 AT, and
must be capable of being made voltage-free by means of an isolating element!
The device must be connected to the same electric circuit and the same fusing, switching
and isolating elements as the corresponding heating or cooling system.
If the device is additionally connected via fusing, switching and isolating elements, then
these must be protected against unauthorised access (e.g. by security seals), so that the
device cannot be put out of operation by unauthorised persons.

9 Operation
9.1 PC-Software AMBUS Win II
The parameters of the device can be set both via keys and display and via one of the data interfaces
with the PC parameterising software AMBUS Win II.
With AMBUS Win II, the meter reading data can be saved, and parameter settings that have to be
executed repeatedly can be stored as macros, which can then be reloaded and run. AMBUS Win II
and the associated operating instructions can be downloaded free of charge at www.aquametro.com.
The use of AMBUS Win II offers advantages if:
•large data records have to be read,
•several devices require identical or similar parameter settings,
•complex applications with inputs/outputs are to be parameterized.
AMBUS Win II and instructions are available as free downloads at www.aquametro.com.

9.3 Right of access, security levels
The parameters for the device can be set entirely via the keys or via the interfaces. The security level
(lock level) determines which parameters can be altered. At the time of delivery, the devices are in
user mode.
Symbol Security level Settings Code At delivery
User mode Only operating language
Service mode All values that are not relevant for calibration,
e.g. initial parameter settings, date/time, meas-
uring point designation etc.
S-Code 1111
no lock Programming
mode All parameters can be set, e.g. initial settings, resetting/synchronising of meter readings etc. P-Code 3132
The codes can be changed in the Basic setting/System submenu.
In EU-compliant devices, activating programme mode will result in the invalidation of the
calibration! The date and time will be recorded in the calibration log and the device dis-
plays an error.
Warning: If you change a code, make sure that you keep it in a safe place. If the code
ist lost, reprogramming is necessary by a service technician on site or in the factory.
