A minimum circuit breaker to use for this system is a 20A, D-curve (note, a 20A C-curve breaker will not discriminate with the rectifier fuse). Therefore, when used with the 2.5mm cable supplied, a 20A, D-curve breaker should be used.

2 NOTE: A larger breaker may be used even though in theory it may appear that the 2.5mm wire is not fully protected. In fact it is protected on two accounts. Firstly it is protected by the rectifier input fuse (which is only a short distance away). Secondly, the rectifiers are power‐limited on their input. Therefore, they can never be overloaded. As a result, the wire can never be over‐loaded by the rectifier – it can only see fault current. As a result, depending on local authorities, only fault current protection may be catered for by the upstream protective device.

The second rate is required specifically for the time-remaining algorithm. A 4 hour rate is usually a good one to use. This information is available from the battery manufacturer’s data sheet. Newmar • PO Box 1306, Newport Beach, CA 92663 • Phone: 714-751-0488 • E-mail: techservice@newmarpower.com... - Page 20 Newmar recommends that you set this value at the highest rate possible to ensure the battery is recharged as fast as possible (this could be as high as 30%, depending on the manufacturer). However, especially in large systems, this may be more limited by the number of rectifiers available, rather than this particular setting.

Some of the Newmar Power System models are provided with Type 2 Surge Protection Devices (SPDs) (as defined by IEC 61643-11). These devices are rated for repeated strikes of 20kA (8/20μs waveform as shown above), and single shot protection of 40kA. - Page 23 Newmar Rectifiers are compliant with EN6100-4-5, Level 4 without any Note: external/upstream surge suppression. To maintain a coordinated approach to surge suppression, Type 2 SPD should be installed upstream if not fitted in the system. To ensure correct operation of the SPDs, at least 10m of AC feeder cable is fitted between the Type 1 and Type 2 protection.

Page 27: Appendix 7 - Field Replacement Of Load Circuit Breakers
Instructions for field installation of load circuit breaker. To be performed by qualified electrical personnel only. 1. Remove the A.C. input and turn both battery breakers off. (If the unit is still powered on a live bus will be exposed creating a possible shock hazard). 2. Remove the top of the unit (there will be 1 screw in each corner and two screws located in the front center of the unit). 3. Remove the bottom circuit breaker toggle guard. 4. The output terminal block wires are labeled according to their position, locate the wire corresponding to the breaker position you are installing and connect it to the bottom contact of the circuit breaker. 5. Attach any hot wire from the bus to the top contact of the circuit breaker. 6. Insert a screw into the hole exposed by removing the bottom toggle guard and screw the breaker in place. 7. Re‐install the toggle guard and top of the unit and reapply power. Note: It is normal to measure output voltage on a Centurion II load circuit breaker when its toggle handle is in the OFF position. The Centurion II circuit breaker alarm circuit produces a very low current, high impedance signal that can be detected using a high impedance digital multi‐meter (DMM). This is normal and does not present a hazard to the user. Newmar • PO Box 1306, Newport Beach, CA 92663 • Phone: 714-751-0488 • E-mail: techservice@newmarpower.com... -
