Electrical connection

3.1 Construction of the MC2A

The measuring amplifier MC2A is housed in a splash−proof cast metal hou-
sing (protection level IP 65). The lid of the housing can be unscrewed. Con-
nection cables are to be fed in through 3 stuffing glands PG 7, for a maximum
cable diameter of 8 mm, to provide the connections for the transducer, the in-
dicator and the supply voltage.
Inside the housing on the printed circuit board there is the clamp strip with
screw clamps which are numbered 1 through 9.
The allocation of terminal numbers (1 ... 9) and their use may be seen on
page 12 and as a connection diagram on the inside of the MC2A cover.
To ensure correct electrical connection it is recommended that the ends of the
wires be twisted or provided with a thimble.
The contact allocation is given on chapter 6.

3.2 Mounting

The measuring amplifier MC2A may be mounted in any attitude. For installa-
tion and mounting the cover shall be removed, by unscrewing the four screws
on the top side. There are two through holes provided in the lower part of the
housing, for the mounting with screws (max. dia. 4 mm).
