Electrical Installation
Electrical Connections
To reduce the risk of electrical shock, the control or metering pump must be plugged into a ground outlet with
ratings conforming to the data on the control panel. It must be connected to a good ground. DO NOT USE
ADAPTERS! All wiring must conform to local electrical codes.
Electrical installation of the DP5000 Series pH Controllers consists of plugging the control module into a proper line outlet.
Based on model number, the following voltages and receptacles are required:
DP5000-1A
DP5000-3A
DP5000-6A
DP5000-01A
DP5000-1B,
DP5000-3B

Connect the pH adjustment pump(s) to the terminal strip for ‘ON/OFF’ control (connect to receptacles directly for 115 V
models) or to cables for ‘PROPORTIONAL’ control. Connect the pH electrode to the BNC connector on the right side of
the control module. Take care not to twist or strain the wires. If equipped, connect the ATC cable (1000
Ω
at 32° F
[0° C]) through the cable gland below the BNC connector to the terminal strip. You may optionally connect an alarm,
solenoid, flow switch and low level switch. You may also connect the mA connections (with the option fitted). The ± 5
V supply for electrode pre-amplification is also accessed on the terminal strip. There is a 500
Ω
maximum resistance
for 4-20 mA option (refer to Figures 4 and 5).
CAUTION
