Handling the cage tension spring clamps

Prepare the connection cables. Remove 8 – 9 mm of the in-
sulation sheath on the end of the cables for the small cage
tension spring clamps. Remove 12 – 13 mm of the insulation
sheath on the end of the cable for the battery connections
(large cage tension spring clamps). Cable end sleeves are not
required.
The spring terminal can be opened up with the aid of a suit-
able slit screwdriver.
Insert the tip of the screwdriver into the upper, square opening,
and push on the spring terminal. The spring terminal in the
lower, round opening opens up.
Insert the cable into the cage tension spring clamp as far as
the insulation (upper, round opening) and remove the screw-
driver. The spring clamp will close again and the cable is se-
cured tightly.
Repeat this procedure for all connections:
+ Charge, + Load, - Battery, + Solar, - Solar.
Ensure that the cable ends are securely clamped into the cage
tension spring clamps!

Connection

Before connecting or disconnecting the cables, the
supply lines to the battery and mains supply must be
disconnected!

Energy source / consumer connection
Connect the device to the energy source (e.g. battery, dynamo,
charger) and the consumers (e.g. refrigerator) as shown in
the wiring diagram. Check that the terminals are connected
correctly.
Always position the fuses close to the energy source
(e.g. battery, dynamo, charger). Only use the specified
cable cross-sections (see table) and fuses of the correct
strength!
Panel MES Module A / B
If you use a Panel MES Module A / B, connect this to the
connections on the device. There is a master switch integrated
into the Panel. Once the Panel is connected, any separate
master switches will become obsolete.
Temperature sensor
If you use a temperature sensor for the battery II, adhere the
temperature sensor to the face side of the battery II (starter
battery). To do this, remove the protective film from the self-
adhesive point of the temperature sensor and press it firmly
onto the desired position of the battery II (see Temperature
sensor description). Connect the cable from the temperature
sensor to the temperature sensor connection of the device.
Battery type changeover switch
Set the battery type (liquid electrolyte or Gel / AGM) of your
battery on the battery switchover.

Connection master switch
When using the Module B without expanding it by attaching
a Panel MES Module A / B, the plug for the separate master
switch is inserted into the 2-pin connection of Module B.
Strain relief
Secure all lines (e.g. to energy sources, consumers and acces-
sories) with the two strain relief plates.
Final tasks
– Check all connections are tight.
– Attach the clamping space cover.
– Finally, connect to the mains on the Module A2.
