Do not remove the debris shield until installation is complete. However,remove the shield before operating the UPS. Once the debris shield is removed, do notplace objects on the ventilation grill.NOTE Remove the UPS cabinet top or bottom conduit landing plate to drill or punchconduit holes (see Drawing 164201603-6 on page A-32).NOTE If the load requires a neutral, a bypass source neutral must be provided. If theload does not require a neutral and there is no neutral conductor connected at thebypass input, a neutral to ground bonding jumper must be installed. DO NOT installboth a source neutral and a bonding jumper. See Table E through Table J or Table Sthrough Table V for neutral bonding jumper wire sizes. Bonding jumper must becopper wire.C A U T I O NHIGH IMPEDANCE GROUND SOURCES - If the supply source is a high impedance ground (IT)type, the input neutral conductor must be connected from the source of supply. If there is nooutput neutral connected to the UPS, the neutral-forming transformer kit (PN 103005400) maybe used instead of pulling a neutral from the source. If the load requires a neutral, then aninput neutral conductor must be pulled into the UPS. In no circumstances shall a neutral toground bonding jumper be installed in the UPS.
