ES210 Hardware Guide: Installation
4
WARNING: The
Bridge also con-
tains a 3V (7 year) lithi-
um battery for time-
keeping purposes. It is
not intended to be oper-
ator- or user-replace-
able. To avoid risk of
personal injury (and
voiding of the Bridge’s
warranty), refer all hard-
ware servicing to For-
tress Technical Support.
 Powering: The Bridge is powered by a 9-30 V DC external
power source and/or a 7.4V lithium ion polymer
rechargeable battery. The wall-mounted (12 V @ 2A)
power supply simultaneously powers and charges the
ES210 Bridge, at a normal load of 6 W (16 W max. during
charging).
 Battery: The 7.4V lithium ion battery cartridge contains
safety devices that protect the 2S (2 Series) cells from
abuse and is keyed to install only in the correct orientation.
 Circuit Overloading: The Bridge includes an internal
resettable fuse on its 9-30V power input. Do not exceed
30V or the unit can be damaged.
 Lightning/Electrostatic Protection: The unit has limited
isolation protection. When attaching external antennas in
an outdoor environment, follow best practices for safety
including the use of in-line lightning arrestors.
 Waterproofing: The Bridge has an IP67 rating when
antennas or protective caps are properly installed.
 Cabling: Cables must be installed in accordance with NEC
Article 725 and 800, and all requirements must be met in
relation to clearances with power lines and lighting
conductors. All cabling must be category 5e per TIA/EIA-
568-B.2.
 Radio Frequency: The Bridge’s internal radio conforms to
the FCC’s safety standard for human exposure to RF
electromagnetic energy, provided that you follow these
guidelines:
 Do not touch or move the antenna while the unit is
transmitting or receiving.
 To safeguard Bridge transmitting circuitry, relocate the
Bridge and its antenna only when the Bridge is powered
off.
 When the Bridge is transmitting, do not hold it so that
the antenna is very close to or touching any exposed
parts of the body, especially the face or eyes.
 Antennas must be installed to provide a separation of at
least 20 cm (7.9") from all persons and any co-located
antenna or transmitter.
 Regarding use in specific environments: • Do not
operate near unshielded blasting caps or in an
explosive environment.
• Limit use in a hazardous
location to the constraints imposed by the location’s
safety director.
• Abide by the rules of the Federal
Aviation Administration for the use of wireless devices
on airplanes.
• Restrict the use of wireless devices in
hospitals to the limits set forth by each hospital.
