Inspect the Battery

Inspect the battery before removing it. Look for:

• Swelling or deformation.

• Indentations or lifting of battery terminals.

• Moisture or liquid on the battery surface.

• Chemical corrosion or deposits on the battery terminals.

! CAUTION

EQUIPMENT DAMAGE

Do not use a device with a damaged enclosure or Lithium battery. Using a

damaged device may further damage the device, cause it to fail, or in hazardous

locations cause other unintended consequences.

If a battery has leaked, do not touch the corrosive electrolyte.

If the battery is damaged or is leaking, follow your site’s hazardous materials handling procedures.

Replace the Battery

We recommend that you replace NG Series Industrial Wireless Gateway batteries in an indoors equipment

room or a similar environment. Do not replace batteries in a hazardous area. Use only approved battery

types described in the relevant NG Series Industrial Wireless Gateway datasheet.

To dispose of used or partially expended batteries, follow your on-site or locally accepted hazardous

materials handling procedures.

Close the Device

To close the device:

1. Ensure that the NG Series Industrial Wireless Gateway lid seal is clean before closing it.

2. Align and fasten the captive screws into the hinges using a cross tightening technique (do not

tighten both screws on one side while leaving both screws on the other side loose).

DO NOT over-tighten the captive screws as this may compromise the lid seal. Fasten captive screws to a

torque of 5Nm.
