Warning
Before any installation of the Control system can take place, make sure the ignition lock is turned off and
the battery is disconnected. Disconnect the device externally before handling it. Also disconnect any
independently supplied output load circuits.
Connecting of Supply Voltage
The supply voltage, should be within the operating range. Connect the supply voltage to power supply.
Protect the module by using a fuse. Requisite fuse level should be 1 A, fast (F). To avoid damage to the
device, connect/disconnect the main connector only if the power supply to the device is switched off.
NOTICE
Connect the WS to the same power and ground as the Control system. The power supply must be
common to both the WS and the Control unit to ensure trouble free communication. Most importantly,
the ground connection, must be the same.
NOTICE
Do not use the chassis as the negative terminal.
Polarity reversal
The WS module is protected against power supply polarity reversal, provided an external fuse, max 1 A
(Fast) is being used. If this fuse is not used, polarity reversal can damage the unit. Do not connect the
housing to Ground externally. This will suspend the reverse voltage protection of the power supply.
Applying a reversed voltage in this case will destroy the supply circuits.
IP 65 protection is only ensured if all connectors are plugged in.
•
Before exposing the device to dust and water, plug in all connectors.
•
Do not immerse the device in water or other liquids.
The maximum torque for fixing the enclosure screws is 1.5 Nm.
•
When opening/closing the enclosure, do not exceed this value.
•
The device can only be repaired by the manufacturer.
Welding
•
Should be done before the installation of the control system. If welding has to be done afterwards,
the electrical connections on the system must be disconnected from other equipment, the negative
cable must always be disconnected from the battery before disconnecting the positive cable, the
ground wire of the welder shall be positioned as close as possible to the place of the welding and the
cables on the welding unit shall never be placed near the electrical wires of the control system.
Operation without antennas can destroy the radio modem.
•
Do not operate the device without antennas.
•
To prevent misuse immediately inform your network operator in case of loss or theft of the SIM card
or the radio modem.
The devices covered in the manual may only be used in mobile or stationary systems in which under
normal operating conditions the separation distance between the antenna(s) and all persons is at least 20
cm (approx. 8 inches). The antenna(s) must further not be co-located or operated in conjunction with any
antenna or transmitter.
According to FCC requirements, the antenna gain, including cable loss, must not exceed the limits of 7.3
dBi in the 850 MHz Cellular band and 12.7 dBi in the PCS 1900 MHz band (WS devices) or 7.2 dBi in the
850 MHz cellular band and 3.5 dBi in the PCS 1900 MHz band respectively (WS devices).
Compliance of WS unit devices in all final product configurations is the responsibility of the integrator.
