Mount and ground chassis

If you intend to install the WR54 in a vehicle, follow these directions for mounting and grounding the
device.

Note Always follow the vehicle manufacturer recommendations for electrical accessories connections.

Mount the device following these general guidelines:

n Device position allows easy access to all ports located on the back of the device.
n Device position allows you to easily view the LEDs located on the front of the device.
n Device location is away from direct exposure to the elements, such as sun, rain, dust, and so

on.

Hardware setup Connect power

For DC installations (with a fixed system ground reference), ground the WR54 chassis to the system
ground reference.

For proper grounding reference:

n Attach the device to a grounded metal surface.
n Connect one end of a short AWG or larger gauge wire to the upper-right grounding hole and

connect the other end to the vehicle chassis.

Special considerations

n Separate Ethernet and power cables from other wiring in the vehicle and route the cables

away from sharp edges.

n Use cable strain relief for installations in high-vibration environments.

WR54 electrical rating

WR54 devices require connection to a conditioned power system that meets these requirements:

n Tolerance within maximum operating voltage range 9 VDC to 36 VDC.
n WR54 power connector on the back of the device requires wiring terminals with the following

specifications:

Wire size: 30-12 AWG
Wire type: copper wire only
Terminal blocks torque: 5-7 pounds per inch

For supply connections, use wires suitable for at least 85° C.

n Power installation must be performed by a qualified electrician, following the National

Electrical Code, ANSI/NFPA 70 and Canadian Electrical Code, Part I, CSA C22.1.

n There must be a disconnect device in front of WR54 devices to protect maintenance workers.

Use a 20 A circuit-breaker as the disconnect device.

n Before doing any maintenance, the maintenance worker must use caution and close the

general power supply.

Hardware setup Connect power

Battery power management

The WR54 power input range is 9-36 VDC. In addition, the WR54 includes a battery saver function. The
WR54 Power Management Unit (PMU) continuously monitors the power input (Vin) and applies the
predefined 10.5 V "turn-off” and 11.5 V "turn-on" supply voltage levels. Once low supply voltage is
detected during operation, the PMU applies the following timeout values before powering off the
WR54:

n If 9 V < Vin < 10.5 V "turn-off" voltage, the unit powers off after 360 seconds.
n If 6 V < Vin < 9 V, the unit powers off after 30 seconds.
n If Vin < 6 V, the unit powers off after 3 seconds.

Once the WR54 is powered off, it will power on again only if Vin > 11.5 V "turn-on” voltage.

Safety notices

n Read all instructions before installing and powering the router. You should keep these

instructions in a safe place for future reference.

n If the power supply shows signs of damage or malfunction, stop using it immediately, turn off

the power and disconnect the power supply before contacting your supplier for a repair or
replacement.

n Changes or modifications not expressly approved by the party responsible for compliance could

void the user’s authority to operate the equipment. Use only the accessories, attachments,

Special safety notes for wireless routers

Digi International products are designed to the highest standards of safety and international
standards compliance for the markets in which they are sold. However, cellular-based
products contain radio devices which require specific consideration. Take the time to read
and understand the following guidance. Digi International assumes no liability for an end
user’s failure to comply with these precautions.

Wireless routers incorporate a wireless radio module. Users should ensure that
the antenna(s) is (are) positioned at least 1 meter away from themselves and
other persons in normal operation.
When in a hospital or other health care facility, observe the restrictions on the
use of mobile phones. Do not use the router in areas where guidelines posted in
sensitive areas instruct users to switch off mobile phones. Medical equipment
may be sensitive to RF energy.
The operation of cardiac pacemakers, other implanted medical equipment and
hearing aids can be affected by interference from cellular terminals such as the
wireless routers when places close to the device. If in doubt about potential
danger, contact the physician or the manufacturer of the device to verify that
the equipment is properly shielded. Pacemaker patients are advised to keep
the wireless router away from the pacemaker while it is on.

Wireless routers must NOT be operated on aircraft. The operation of wireless
appliances in an aircraft is forbidden to prevent interference with
communications systems. Failure to observe these instructions may lead to the
suspension or denial of cellular services to the offender, legal action, or both.

As with any electrical equipment, do not operate the router in the presence of
flammable gases, fumes or potentially explosive atmospheres. Do not use radio
devices anywhere that blasting operations occur.

Digi WR54 regulatory and safety statements Product disposal instructions

Wireless routers receive and transmit radio frequency energy when power is on.
Interference can occur when using the router close to TV sets, radios,
computers or inadequately shielded equipment. Follow any special regulations
and always power off your router wherever forbidden or when it may cause
interference or danger.

SOS IMPORTANT! Wireless routers operate using radio signals and cellular
networks cannot be guaranteed to connect in all possible conditions. Therefore,
never rely solely upon any wireless device for life critical communications.
