MOUNTING
All 1050 and 1550 units weigh approximately
20lbs (9.1 kg) and can be safely mounted on
either a horizontal or vertical surface. Mount
the unit in a dry and well ventilated location at
least 1 inch (2.54 cm) surrounding clearance.
The W-series models are designed to meet
IP66 rating, and is resistant to water spray
from any direction. These units can be
mounted in wet locations but are not suitable
for submersion. The Y-series models are
designed and certied to meet IP67 rating.
These units are resistant to water immersion of a depth up to 1 meter for 30 minutes and suit-
able for mounting in locations such as a vehicle fording a river.
CAUTION: NEVER CONNECT OR DISCONNECT ANYTHING TO THE UNIT’S INPUT OR
OUTPUT WHILE IT IS ON!
To prevent the risk of high voltage electric shock, never connect or disconnect anything to/from the
unit’s input or output connections while the power switch is ON.
GROUNDING
The unit case is connected to AC Ground and AC Neutral in order to meet regulatory
requirements and reduce the possibility of it generating any radio frequency interference.
The unit case must be bonded appropriately to the grounding system of the vehicle or marine
vessel. On a vehicle, bond the case to the vehicle’s frame. On a marine vessel, bond the case
to the vessel’s hull. A grounding stud is provided on the front panel for this purpose.
To ensure proper grounding, check the connection with an ohmmeter. The case is isolated from
the DC input, so the DC power can be connected to a different ground from the AC output.
DISCONNECTING
If you need to disconnect the unit for service or storage:
1. Move the power switch to OFF and disconnect the power source and load
2. With power disconnected, move the power switch to ON.
3. Leave the switch in this position for one minute to discharge the storage capacitors.
4. Return the power switch to the OFF position.
5. The power supply or battery charger is ready for service or storage.
