3 Installation
3.1 Mounting
Three M4 threaded holes in the bottom of the MRL-2 (H) make it easy to mount the device.
Always obey all applicable safety regulations and never use the device outside the specifications stated
under 4 Technical data on page 15
3.2 Device wiring
3.2.1 Power Supply
For trouble free operation use a separate power supply for the MRL-3 (H)
MRL-3
9…30V, 0.5A DC
MRL-3 (H)
24…30V DC, 2.5A DC
3.2.2 Cable connection
A ferrite must be mounted to the connecting cable. Use a ferrite with an impedance of 150
to 260 at
25MHz and 640 to 730
at 100MHz. As example you can use SFC10 from KE Kitagawa.
3.2.3 Shield and Ground
The MRL3 (H) contains two electrical isolated grounds, the general ground (GND) and the analog ground
(AGND). GND and AGND are connected to the housing by a RC element. Please see figure 3
