Fusing
For DC installations, Sierra Wireless recommends fusing the power input using a 2.0 A
fast-acting fuse. Install the fuse on the positive line, as shown in
Figure 3-3 on page 31.
Grounding the ES Series Gateway Chassis
For DC installations (with a fixed “system” ground reference), Sierra Wireless
recommends always grounding the ES450 chassis or the mounting bracket to the system
ground reference. To ensure a good grounding reference, use a short wire with a gauge of
18 AWG or larger connected to one of the mounting holes with the screws and lock
washers provided in the supplied mounting kit.
