technicians.
• Products are tested for indoor use.
2.2 Input Requirements
The EN1501 and EN1501-XL require the following input specifications for
compatibility with the meter:
• A dry contact such as a reed switch.
• The pulse width of a switch output when it is activated must be greater
than or equal to 10ms.
• A maximum rate of six pulses per second.
• Closed impedance of the pulser mechanism must be smaller than 1k
ohm.
• Open impedance of the pulser mechanism must be greater than five
megohms.
2.3 Connect Transmitter to Meter
Connect the transmitter to the meter as follows:
1. Open the housing by pressing down on the base tab near the wiring
through-hole while lifting away the cover.
2. Fully insert stripped wires into the removable header terminal.
3. Use a small Phillips screwdriver to tighten the screws that secure wires
to the removable header terminal.
4. Attach removable header terminal (if removed) to the transmitter board
as shown.
Note: If connecting to a meter that has polarity to its pulse output, the
negative (–) should be connected to the outside terminal, closest to the
corner of the board.
