Installation
Before You Begin
Review the basic site criteria in this sub-section before installing the GSM.
Safety Considerations
• The GSM is not suitable for use over hazardous locations. Refer to MDE-2530 Pump and
Dispenser Installation Manual for information on hazardous locations.
• Site electrical service must comply with all installation requirements for a complete
fueling system.
Choosing a Location
• Locate the GSM (PA0258XXXXXXX) in an area with an office-type environment not
subject to extreme variations in temperature. The ambient temperature must be between
+50 ºF (+10 ºC) and +104 ºF (+40 ºC) for PA025800XXXXX, and -22 ºF (-30 ºC) to
+158 ºF (+70 °C) for PA025801XXXXX.
• Locate the GSM in an area with minimal possibility of liquid spills.
• Locate the GSM in a position away from direct sunlight. If necessary, provide a suitable
sun screen.
Installing Cables
• Install all cables so that they are protected from damage or accidental disconnection.
Route along a wall or under a counter and secure with cable ties or suitable cable clamps.
• Route cables away from fluorescent lights, compressor wiring, or other sources of
electrical interference.
Connecting the GSM and Controller
• Connect the GSM to a dedicated circuit with an Isolated Ground Receptacle
(Hubbell
®
5261 or equivalent).
• This circuit must NOT share the conduit with wiring for devices that draw high amperage
(compressor, freezer, STP, and so on) or a device that is a source of Radio Frequency
Interference (TV, microwave, intercom, two-way radio, and so on).
• Ideally the GSM should be powered by the same outlet as the POS to which it is
connected. At a minimum it should share a breaker with the POS Controller (C-2,
PC-based G-SITE POS system, Passport POS system, third-party POS, and so on).
• GSM and Controller must be on the same phase of AC power.
