APPENDICES
Opening & Closing the iPack
Installing or changing a GSM SIM card or iPack battery requires opening the iPack. It is important that
this is done carefully to avoid damaging internal wiring or the iPack’s weatherproof seal.
Opening the iPack
Be sure to touch the metal shell of the DB25 connector on the iPack before opening the enclosure in
order to safely discharge any static electricity.
The iPack enclosure consists of two halves secured together by four recessed screws, two from each side
of the enclosure. A gasket in between the two halves and 8 o-rings provide an environmental seal for
the iPack and protect the internal electronics from the elements.
Remove the four recessed screws, and the iPack will separate into two halves connected by a short
cable. One half contains the iPack electronics and the other half contains the rectangular battery, which
is secured by Velcro. Try not to lose any of the o-rings, and be careful not to rip or tear the gasket if it
should come loose.
Closing the iPack
1.
Insert the (4) 2-½ inch mounting screws up through the half of the enclosure that contains
the iPack electronics.
2.
Slide the (4) o-rings over the screws.
3.
Set the gasket into the groove of the shell.
4.
Slide the cover (the half with the battery) over screws, being careful not to pinch the battery
cable.
5.
Make sure the gasket is not pinched and then install the screws. It is a good idea to make
sure the screws fall back into the existing threads in the iPack enclosure. An easy way to do
this is to gently turn the screw counterclockwise one turn – it will fall into the existing
threads in the iPack enclosure.
