2 Removable (outside) filling connections must be used. 3 The container space must be vented to the outside. CAUTION: Installing the VML750 at the end of the vehicle above the exhaust pipe may cause the VML750 to overheat. CAUTION: Check the required mounting locations. It might be necessary to penetrate the firewall to reach the battery.
Powering Up the Modem. The VML750 can be installed on a flat surface or a side wall of a vehicle. Before beginning the installation, make sure that the space available at the installation site is adequate for the modem and its accessories. Each installation configuration may require a different area for mounting the modem without obstruction.
• Before installing the antenna cables, add an identical label on both ends of each cable to ensure correct connection between the antenna and its related connector on the VML750 back panel. • Plan wire and cable routing to provide maximum protection from overheating, battery acid, moving parts, and sharp edges.
NOTICE: before installing the antenna cables, add an identical label on both ends of each cable to ensure correct connection between the antenna and its related connector on the VML750 back panel. The VML750 antenna is used to enhance the reception capability in poor reception areas and support Multiple Input Multiple Output (MIMO) modes for LTE.
