An external UPS maintenance bypass switch provides additional maintenance and service facilities to a uninterruptible power supply installation. Also referred to as a bypass switch or wraparound panel, the device allows the UPS to be isolated safely for maintenance work or removal without interruptible to the load. UPS maintenance bypasses from Server Room Environments include standard products for wall or rack mounting and bespoke bypass solutions made to order with options for parallel UPS installations and Castell interlocks.
A UPS maintenance bypass switch must be matched correctly to the uninterruptible power supply it is to be installed with. The principle considerations include:
If a project requires a custom bypass panel or switch this can be designed and once approved manufacture within 10-15 working days. Custom options include interlocking (Castell), volt-free signal contacts for remote monitoring, built-in panel meters and LCD panels, a local power sockets for service engineer use, and parallel UPS operation. Bypasses may also be supplied with additional protection including lighting and surge protection. Custom panels can also be painted to virtually any specific data centre colour schemes.
