Installation
All local and national electrical safety codes (NESC®) must be followed when installing the MP2. 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
®
MP2 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).

Powering and Grounding
3.2.1
Powering the MP2
Follow all national and local electrical codes when powering the MP2. Quest recommends a minimum
of 18AWG conductor for powering. The TELSEC
®
MP2 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 MP2 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 MP2
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
Removing the Battery Insulator
The MP2 is shipped with an insulator to keep the battery disengaged from the system. Remove the
insulator once the unit is permanently powered, by pulling the tab in front of the unit. The system uses
the battery to save the system time and input time status.
