Important Notice
ELPRO products are designed to be used in industrial environments, by experienced industrial engineering personnel
with adequate knowledge of safety design considerations.
ELPRO products are designed to operate in the presence of noise and interference, however in an extreme case, noise
and interference could cause product operation delays or operation failure. Like all industrial electronic products, ELPRO
products can fail in a variety of modes due to misuse, age, or malfunction. We recommend that users and designers
design systems using design techniques intended to prevent personal injury or damage during product operation, and
provide failure tolerant systems to prevent personal injury or damage in the event of product failure. Designers must warn
users of the equipment or systems if adequate protection against failure has not been included in the system design.
Designers must include this Important Notice in operating procedures and system manuals.
These products should not be used in non-industrial applications, or life-support systems, without consulting ELPRO
Technologies first.
As a license free, quad band capable product, the 605M-D1 GSM/GPRS modem must used in accordance with local
regulatory and communications authority guidelines. This includes the use of antenna and other radio communications
accessories which form part of the communications between points in the network.
To avoid the risk of electrocution, The antenna, coaxial, and serial cables and all terminals of the 605M-D1 module should
be electrically protected. To provide maximum surge protection, the module should be connected to a suitable earth and
the module should be installed as recommended in the Installation Guide.
To avoid accidents during maintenance or adjustment of remotely controlled equipment, all equipment should be first
disconnected from the 605M-D1 module during these adjustments. Equipment should carry clear markings to indicate
remote or automatic operation. E.g. "This equipment is remotely controlled and may start without warning. Isolate at the
switchboard before attempting adjustments."
The 605M-D1 module is not suitable for use in explosive environments without additional protection.
To minimise any implementation problems, prior to commissioning in the field it is strongly recommended that:
• A check is performed to ensure reliable signal strength is available at the proposed installation site.
• The configuration/operation of the modem is tested on a work bench.
Repairs to the 605M-D1 GSM/GPRS modem should only be attempted by ELPRO personnel or upon consultation with
ELPRO, its nominated representative and/or qualified technical personnel.
DO NOT:
• Operate the equipment near electrical blasting caps or in an explosive atmosphere
• Operate the transmitter when someone is within 20 cm (~ 8 inches) of the antenna.
• Operate the transmitter unless all RF connectors are secure and any open connectors are correctly terminated.
