PRODUCT DESCRIPTION
MTP-D010 potentiometer series are intended for direct control of EC fans / motors
and actuators. ey require a supply voltage of 3—15 VDC and provide a stepless
output signal that can be set by a rotary knob within a range adjustable via two
trimmers for Vmin (10—70 % Vin) and Vmax (30—100% Vin). ey are suitable for
applications where a DC control signal is required. e -AT version features an off
position, while -BT provides control within the range Vmin—Vmax. eir enclosures
are splash-proof and suitable for both inset and surface mounting.

MOUNTING INSTRUCTIONS IN STEPS
Before you start mounting your potentiometer, read carefully “Safety and Precautions”
and follow the steps:
For inset mounting
1. Remove the knob by turning it to the right until it pops out.
2. Unscrew the loose nut to remove the cover of the external enclosure.
3. Do the wiring according to the wiring diagram (see Fig. 1 Wiring and connections).
4. Mount the internal enclosure into the wall according to the mounting dimensions
shown in Fig. 2 Mounting dimensions - inset mounting.
