Installation
All local and national electrical safety codes (NESC®) must be followed when installing the MP2x. If
there is any contradiction in this manual and those standards, then the installer must follow the local
and national codes. Use copper conductors only. The TELSEC
®
MP2x is designed for mounting on a wall
or within a rack. Rack mounting is accomplished by using the optional (not included) mounting ears for
a 19 or 23” rack. Contact your Quest representative to order
the Rack Mounting Ear kit (PN 150989).
3.1
Mounting the MP2x
Install the MP2x in the desired location using #8 hardware to connect the two mounting tabs to the wall.
For mounting
in a 19” rack, use the optional mounting ears Quest p/n 150989.

Powering and Grounding
3.2.1
Powering the MP2x
Follow all national and local electrical codes when powering the MP2x. Quest recommends a minimum
of 18AWG conductor for powering. The TELSEC
®
MP2x will operate from 18-65 VDC power (50 mA max
at 48 VDC). The power input is isolated from the rest of the system and will work on either a positive or
negative DC system. The MP2x supports power from a dual (A & B) feed DC power system to provide
redundancy in case one of the feeds is lost. Connect the power source A and B (optional) to the MP2x
observing the polarity markings on the enclosure. Quest recommends fusing each power source at 1 A.
Reverse polarity will not damage the unit, but it will not operate until corrected. It is recommended that
all input wiring be completed with no power to the system. Turn on power once all wiring is verified.
3.2.2
Grounding the MP2x
There is a ground post on the left and right side of the chassis. Place a ground wire using a minimum 12
AWG conductor from the Electrical panel ground bus (or other approved grounding point) to the ground
terminal on the MP2x. Follow national and local codes and practices for properly grounding the system.
