• Temperature rating: Min. 105 °C/ 221°F
• Max. length: 12 m/ 39 ft at 12 VDC, 200 m/ 656 ft at 24 VDC
• UV resistant cable
Requirements for LAN (PoE) input
Observe the following requirements for connecting power to the LAN input:
• Must comply with the requirements for PoE+ IEEE 802.3at type 2 class 4.
• Cable requirements:
• Temperature rating: Min. 95 °C/ 203°F
• PoE+ mode A and/or B (both are supported, see Connector pin-out on page A-2)
To connect to the DC input
Use a flat blade screw driver (max. 3.5 mm/ 0.14" wide) to unscrew and fasten the
screw terminals. Do as follows:
1. Lead the cable through the cable gasket at
the DC input.
2. If the DC cable is shielded, insert the end of
the shield into the screw terminal 3-GND in
the DC terminal block and tighten the screw
to torque 0.5 N m/ 4.5 lbf in.
3. Insert the negative wire into the terminal
marked 2-DCIN- in the DC terminal block
and tighten the screw to torque 0.5 N m/ 4.5
lbf in.
4. Insert the positive wire into the terminal
marked 1-DCIN+ in the DC terminal block and tighten the screw to torque 0.5 N m/
4.5 lbf in.
5. Tighten the cable gland.

CAUTION!
Make sure there is no power on the cables while you connect
them to the EXPLORER 540.
CAUTION!
3-GND is only for
connection of
shield!
Do not connect the
positive or
negative wire to
3-GND!
If you are using the EXPLORER 540 Cellular Modem, the antenna
cable(s) go through the same cable gland as the DC input. In that
case, use cable glands of Ø3.2 mm (RG316) and add silicone glue
inside the cable gland gasket to make sure that the cable gland is
waterproof before tightening the cable gland. It is vital for the life of
the product that the cable gland is waterproof!
