Page 3: Admonishments
1. ADMONISHMENTS The admonishments are the symbols and wording used in this manual to alert readers to specific dangers and instructions. The meanings of the various admonishments are explained as follows: Warning = risk to life or personal injury and equipment damage Caution = risk of equipment damage. -

AC SURGE SUPPRESSION - If these systems are used in outdoor cabinet applications, the fitment of a Type 2 AC Surge Suppression Device is mandatory (see Appendix 2). If a Type 2 SPD is NOT fitted, the warranty is void. RECEIVING INSTRUCTIONS Newmar provides all equipment to the delivering carrier securely packed and in perfect condition. -
Page 5: System Overview
SYSTEM OVERVIEW The Sentinel Rectifier System can hold three rectifier modules and have a maximum power output of 1.8kW, producing a maximum current output of 33.3A at 54 VDC. Peak current is 37.5A @ 48 VDC. The system is intended to be a complete power system in a box, so no connections need to be made internally. AC connection is via rear exiting lead with all the DC (Load and Battery) connections are made at the front of the unit. -

Green Wire White Wire Earth (Green) Neutral (White) Live (Black Black Wire Fig 2, AC Cable Detail Connections should allow for a maximum single phase AC supply of 16.5A (@ 110VAC) (see next section). The AC earth is internally bonded to the system chassis. DC Common (+48VDC) is connected to the AC earth through the placement of the PCB connecting the backplane to the distribution. -

Alarm and communication cables terminate directly into the connectors of the Supervisory Module, SM36, which terminals are assessable by pulling the monitor forward to expose connections (see Fig 6 & 7). Cables can be routed through the front of the system via the cable exit indicated. When routing the cables, ensure they are kept away from the AC and DC Fig 6. -

LVD OPERATION The primary Low Voltage Disconnect contactor is in the battery side of the DC distribution. A secondary Load Low Voltage Disconnect can be optionally included in a section of the load side of the DC distribution. -

immediately. ESSENTIAL SYSTEM SET-UP PARAMETERS The following steps are system settings that must be checked at the time of commissioning for each system installed. You can print this section and fill it out for each site commissioned. Note: these steps are battery chemistry dependent. Follow the appropriate section. 11.1. - Page 18 Site / Settings: If you choose not to enable Temperature Compensation, then set the Rectifier Float Voltage to that required by the battery manufacturer for the average long-term temperature you anticipate your system to operate at. Set Battery Capacity Consult the battery manufacturer’s data for correct battery capacity settings.
- Page 19 Site Settings: / Set Battery Current Limit Consult battery manufacturer’s data for maximum battery recharge current settings. The Battery Current Limit is set as a percentage of the 10-hour rate entered above. It is recommended this value is set at the highest rate allowable to ensure the battery is recharged as fast as possible.

Low Voltage Disconnect Settings The LVD disconnect set points are usually a customer generated setting. As the discharge time increases, the higher the end voltage should be set. For a discharge of <1hr, this may be as low as 1.75Vpc (42.0V for a “48V” battery), or for an 8-hour discharge, it may be 1.85Vpc (44.4V for a “48V”... - Page 21 Depending on the test load available, it may be necessary to adjust the High Load Current alarm threshold down to suit. For example, with 40A test load, adjust the Load Current High Setpoint threshold (Web UI page Alarm Configuration>System Alarms) to 35A.

A Battery MCB Fail alarm is generated from the voltage measured across the battery MCB. Therefore, to check a Battery MCB Fail alarm, simply open one of the battery MCB’s. If batteries are connected to the system at this time, the alarm may take a few moments to activate. - Page 23 Modular Smart Lithium Battery Selection If the system is connected via Modbus RTU to a battery BMS check the correct specific battery is selected from the Product drop down list and / mapped to the correct address.
