Page 8: Installation
Warranty and Safety Conditions 3.3 Installation • This product is intended to be installed only in restricted access areas as defined by UL60950 and in accordance with the National Electric Code, ANSI/NFPA 70, or equivalent agencies. • The Inverter System may contain output over current protection in the form of circuit breakers. In addition to these circuit breakers, the user must observe the recommended UL listed upstream and downstream circuit breaker requirements as defined in this manual. -
Page 9: Surge And Transients
Warranty and Safety Conditions 3.3.2 Surge and transients The mains (AC) supply of the modular inverter system shall be fitted with Lightning surge suppression and Transient voltage surge suppression suitable for the application at hand. Manufacturer’s recommendations of installation shall be adhered to. -
Page 10: Purpose And Applicability
This document applies to the following models of the Comm/net Systems, Inc external wraparound wall-mounted manual bypass switch (MBS): • 016-1895-10 r02: MBS; Rack Cabinet; 250A; 120/208VAC; 3PH; Rotary Switch Type; Make-Before-Break; Handshake Interlock; Up to ( 4 ) 3-pole breaker positions. -
Page 11: Theory Of Operation
• Handshaking interlock feature compatible with CE+T inverters when bundled at time of purchase. • Rotary ON/OFF inverter AC feed switch to safely remove AC power from the inverter ( 016-1895-10 model ). Also allows testing of inverter while load is on Bypass. -
Page 12: Unpacking And Inspection
Unpacking and Inspection 6. Unpacking and Inspection The Comm/net Systems MBS was carefully packaged at the factory to withstand the normal rigors of shipping. However, you should carefully inspect the box and contents to confirm that no damage has occurred in transit. Most shipping carriers require notification of shipping damage within twenty-four hours of delivery, and it is the responsibility of the recipient to inspect the shipment immediately upon receipt. -

Page 18: Adding Loads
Installation 7.7 Adding Loads Warning: Ensure Breakers are in the off position before proceeding. Step 1. Remove the deadfront panel by uninstalling the (9) #12-24 screws (see Figure 13) . Step 2. Terminate GROUND connection to GROUND bar (see Figure 14) . Figure 13. -
Page 19: Operation
8.1 Features Overview The MBS includes two rotary switches located on the front of the panel: • INVERTER AC FEED - this switch ( circuit breakers on 016-1895-10 model ) controls AC power to the inverter mains input. • SOURCE - this switch determines whether loads are fed from the inverter ( NORMAL ) output or from the mains ( BYPASS ). -
Page 20: Alarm Contacts
Operation 8.1.3 Alarm Contacts The MBS features alarm contacts that can be used to remotely monitor MBS status. The corresponding alarm relay will be active under any of the following conditions: • Mains AC Fail • SOURCE Switch Not in NORMAL Position •... -
Page 21: Emergency Interlock Release
Operation 8.4 Emergency Interlock Release Warning Be sure the two sources are synchronized prior to using this feature. Failure to do so may cause premature switch contact wear, switch damage, and/or loss of power to load equipment. In situations where the inverter cannot provide the ready signal ( inverter not yet installed, or inverter failure ), a means is provided to release the interlock at the MBS. -
