External manual bypass

Without an external bypass switch, such as Riello UPS's Multi Pass, to allow for preventive maintenance opportunities, the only safe alternative is to power down the entire critical load, not just the UPS system. The external maintenance bypass will use a manual switching method to transfer the load between UPS output and the mains power supply. This can comprise of a single transfer switch (three . External Manual Bypass Switch: The manually operated make-before-break bypass switch is located in a separate enclosure from the UPS. Commonly, the separate enclosure is wall mounted or in a matching sidecar cabinet to the UPS. Similar to the internal bypass switch, the UPS load can be seamlessly transferred between the UPS and bypass power source. The External manual bypass switch totally . 1. Select a mounting location for the bypass switch within sight of the UPS. 2. Use the provided wallmount brackets to firmly secure the BPM to the wall (Figure 12). NOTE The bypass switch should be mounted securely to a sturdy surface. You may need.

External Manual Bypass Switch: The manually operated make-before-break bypass switch is located in a separate enclosure from the UPS. Commonly, the separate enclosure is wall mounted or in a matching sidecar cabinet to the UPS. Similar to the internal bypass switch, the UPS load can be seamlessly transferred between the UPS and bypass power source. The External manual bypass switch totally isolates. 1. Depress and hold the Red Button, then rotate the MBS switch to the “Bypass” position and apply input power supply. This will allow the critical load to be tested with raw AC power. 2. Place the bypass switch into the “Test” position. The UPS can now be started in accordance with the UPS User’s Manual. 3. An external manual bypass switch enables an uninterruptible power supply system to be locally isolated for maintenance or replaced without any disruption to the load. If the external manual bypass switch (EMBS) is supplied with or before the UPS system, it enables the electricians to complete all of the ac cabling and turn the load on. Then, when it comes to installing the UPS system, we can connect the UPS to the EMBS, and once the UPS system is turned on, we can seamlessly switch the load.

A range of fully customisable external maintenance bypass switches (EMBS), manufactured to the highest quality and designed to allow the isolation of UPS. 1 sept An external maintenance bypass switch is used to isolate the Uninterruptible Power Supply during routine maintenance such as unit. With an external maintenance bypass switch as part of your back up power solution, you can quickly and easily divert the mains supply around the UPS.
