1.0 Installation requirements
1.1 Wiring harness
The ems75vr is provided with a wiring harness that is suitable for internal wiring only. The mounting, secureness,
segregation requirements and acceptability of the wiring harness are to be investigated and considered under
the requirements of the ultimate end-use application.
1.2 Ground continuity
The metal bracket used to mount the ems75vr is secured in position using two self-drilling screws. After securing
the bracket into position, ground continuity tests must be performed to ensure that the installation meets local
regulations for grounding of metal parts. If the ground continuity tests fail, a separate ground wire should be
used between the metal bracket and vending machine, and the ground continuity tests repeated.
1.3 Installation kit
The ems75vr installation kit consists of the following:
ems75vr controller mounted on a bracket complete with a remote display, wiring harness, appliance
sensor, and motion sensor (not attached to cable).
No. 4 self-tapping screws (x2) to secure the motion sensor.
No. 8 self-drilling screws (x2) to secure the bracket.
Note: The motion sensor is supplied detached from the cable to facilitate installation.

1.4 Tools required
The following tools are required (not supplied):
Drill driver
5/64”drill bit
1/2” deep well socket
1/4” nut setter
11/32” nut driver
No. 2 Phillips head bit
No. 2 Phillips head screwdriver
Cable ties.
Note: Do not over tighten cable ties.
Note: Cable ties must not be used to secure the sensor head. This will invalidate the warranty.
1.5 Before installation
The vending machine should be checked to ensure that it is in good working order before the ems75vr kit is
installed.
