3 Mounting
The charge amplifier is supplied with two stainless mounting screws M4. The housing does not have
to be opened for mounting, because the screws are already inserted.
The dimensions of the mounting holes are 86 x 36mm (see Section 7.4), minimum thread depth 8mm.
The screws can be tightened through the holes in the lid using an hex wrench (3mm), and secured
with Loctite if necessary.
If longer screws are required, the lid must be unscrewed. Insert new screws with tooth lock washer.
For connecting the plug, see Section 5 Start up.
Notes:
For EMC reasons, we recommend to connect the mounting plate to earth (mounting position).
The charge amplifier can be fitted in any position, but if it is arranged vertically, mounting with plugs
pointing downward is preferred.
